This release's theme is one that is likely to repeat for a few releases: convergence with the WebGPU specification! WGPU's design and base functionality are actually determined by two specifications: one for WebGPU, and one for the WebGPU Shading Language.
This may not sound exciting, but let us convince you otherwise! All major web browsers have committed to offering WebGPU in their environment. Even JS runtimes like [Node][nodejs-webgpu-interest] and [Deno][deno_webgpu-crate-manifest] have communities that are very interested in providing WebGPU! WebGPU is slowly [eating the world][eat-the-world-meaning], as it were. 😀 It's really important, then, that WebGPU implementations behave in ways that one would expect across all platforms. For example, if Firefox's WebGPU implementation were to break when running scripts and shaders that worked just fine in Chrome, that would mean sad users for both application authors _and_ browser authors.
WGPU also benefits from standard, portable behavior in the same way as web browsers. Because of this behavior, it's generally fairly easy to port over usage of WebGPU in JavaScript to WGPU. It is also what lets WGPU go full circle: WGPU can be an implementation of WebGPU on native targets, but _also_ it can use _other implementations of WebGPU_ as a backend in JavaScript when compiled to WASM. Therefore, the same dynamic applies: if WGPU's own behavior were significantly different, then WGPU and end users would be _sad, sad humans_ as soon as they discover places where their nice apps are breaking, right?
The answer is: yes, we _do_ have sad, sad humans that really want their WGPU code to work _everywhere_. As Firefox and others use WGPU to implement WebGPU, the above example of Firefox diverging from standard is, unfortunately, today's reality. It _mostly_ behaves the same as a standards-compliant WebGPU, but it still doesn't in many important ways. Of particular note is Naga, its implementation of the WebGPU Shader Language. Shaders are pretty much a black-and-white point of failure in GPU programming; if they don't compile, then you can't use the rest of the API! And yet, it's extremely easy to run into a case like that from <https://github.com/gfx-rs/wgpu/issues/4400>:
return 42; // fails in Naga, but standard WGSL happily converts to `f32`
}
```
We intend to continue making visible strides in converging with specifications for WebGPU and WGSL, as this release has. This is, unfortunately, one of the major reasons that WGPU has no plans to work hard at keeping a SemVer-stable interface for the foreseeable future; we have an entire platform of GPU programming functionality we have to catch up with, and SemVer stability is unfortunately in tension with that. So, for now, you're going to keep seeing major releases and breaking changes. Where possible, we'll try to make that painless, but compromises to do so don't always make sense with our limited resources.
This is also the last planned major version release of 2024; the next milestone is set for January 1st, 2025, according to our regular 12-week cadence (offset from the originally planned date of 2024-10-09 for _this_ release 😅). We'll see you next year!
### Contributor spotlight: @sagudev
This release, we'd like to spotlight the work of @sagudev, who has made significant contributions to the WGPU ecosystem this release. Among other things, they contributed a particularly notable feature where runtime-known indices are finally allowed for use with `const` array values. For example, this WGSL shader previously wasn't allowed:
```wgsl
const arr: array<u32,4> = array(1, 2, 3, 4);
fn what_number_should_i_use(idx: u32) -> u32 {
return arr[idx];
}
```
…but now it works! This is significant because this sort of shader rejection was one of the most impactful issues we are aware of for converging with the WGSL specification. There are more still to go—some of which we expect to even more drastically change how folks author shaders—but we suspect that many more will come in the next few releases, including with @sagudev's help.
We're excited for more of @sagudev's contributions via the Servo community. Oh, did we forget to mention that these contributions were motivated by their work on Servo? That's right, a _third_ well-known JavaScript runtime is now using WGPU to implement its WebGPU implementation. We're excited to support Servo to becoming another fully fledged browsing environment this way.
Dynamic dispatch between different backends has been moved from the user facing `wgpu` crate, to a new dynamic dispatch mechanism inside the backend abstraction layer `wgpu-hal`.
Whenever targeting more than a single backend (default on Windows & Linux) this leads to faster compile times and smaller binaries! This also solves a long standing issue with `cargo doc` failing to run for `wgpu-core`.
Benchmarking indicated that compute pass recording is slower as a consequence, whereas on render passes speed improvements have been observed. However, this effort simplifies many of the internals of the wgpu family of crates which we're hoping to build performance improvements upon in the future.
By @wumpf in [#6069](https://github.com/gfx-rs/wgpu/pull/6069), [#6099](https://github.com/gfx-rs/wgpu/pull/6099), [#6100](https://github.com/gfx-rs/wgpu/pull/6100).
Current users of `.global_id()` are encouraged to make use of the `PartialEq`, `Eq`, `Hash`, `PartialOrd` and `Ord` traits that have now been implemented for `wgpu` resources.
https://gpuweb.github.io/gpuweb/#programmable-passes-bind-groups specifies that bindGroup is nullable. This change is the start of implementing this part of the spec. Callers that specify a `Some()` value should have unchanged behavior. Handling of `None` values still needs to be implemented by backends.
For convenience, the `set_bind_group` on compute/render passes & encoders takes `impl Into<Option<&BindGroup>>`, so most code should still work the same.
One of the changes in the WebGPU spec. (from [about this time last year][optional-entrypoint-in-spec] 😅) was to allow optional entry points in `GPUProgrammableStage`. In `wgpu`, this corresponds to a subset of fields in `FragmentState`, `VertexState`, and `ComputeState` as the `entry_point` member:
```wgsl
let render_pipeline = device.createRenderPipeline(wgpu::RenderPipelineDescriptor {
module,
entry_point: Some("cs_main"), // This is now `Option`al.
// …
});
let compute_pipeline = device.createComputePipeline(wgpu::ComputePipelineDescriptor {
module,
entry_point: None, // This is now `Option`al.
// …
});
```
When set to `None`, it's assumed that the shader only has a single entry point associated with the pipeline stage (i.e., `@compute`, `@fragment`, or `@vertex`). If there is not one and only one candidate entry point, then a validation error is returned. To continue the example, we might have written the above API usage with the following shader module:
```wgsl
// We can't use `entry_point: None` for compute pipelines with this module,
// because there are two `@compute` entry points.
@compute
fn cs_main() { /* … */ }
@compute
fn other_cs_main() { /* … */ }
// The following entry points _can_ be inferred from `entry_point: None` in a
// render pipeline, because they're the only `@vertex` and `@fragment` entry
#### WGPU's DX12 backend is now based on the `windows` crate ecosystem, instead of the `d3d12` crate
WGPU has retired the `d3d12` crate (based on `winapi`), and now uses the `windows` crate for interfacing with Windows. For many, this may not be a change that affects day-to-day work. However, for users who need to vet their dependencies, or who may vendor in dependencies, this may be a nontrivial migration.

For the first time ever, WGPU is being released with a major version (i.e., 22.* instead of 0.22.*)! Maintainership has decided to fully adhere to [Semantic Versioning](https://semver.org/)'s recommendations for versioning production software. According to [SemVer 2.0.0's Q&A about when to use 1.0.0 versions (and beyond)](https://semver.org/spec/v2.0.0.html#how-do-i-know-when-to-release-100):
> If your software is being used in production, it should probably already be 1.0.0. If you have a stable API on which users have come to depend, you should be 1.0.0. If you’re worrying a lot about backward compatibility, you should probably already be 1.0.0.
It is a well-known fact that WGPU has been used for applications and platforms already in production for years, at this point. We are often concerned with tracking breaking changes, and affecting these consumers' ability to ship. By releasing our first major version, we publicly acknowledge that this is the case. We encourage other projects in the Rust ecosystem to follow suit.
Note that while we start to use the major version number, WGPU is _not_ "going stable", as many Rust projects do. We anticipate many breaking changes before we fully comply with the WebGPU spec., which we expect to take a small number of years.
### Overview
A major ([pun intended](#our-first-major-version-release)) theme of this release is incremental improvement. Among the typically large set of bug fixes, new features, and other adjustments to WGPU by the many contributors listed below, @wumpf and @teoxoy have merged a series of many simplifications to WGPU's internals and, in one case, to the render and compute pass recording APIs. Many of these change WGPU to use atomically reference-counted resource tracking (i.e., `Arc<…>`), rather than using IDs to manage the lifetimes of platform-specific graphics resources in a registry of separate reference counts. This has led us to diagnose and fix many long-standing bugs, and net some neat performance improvements on the order of 40% or more of some workloads.
While the above is exciting, we acknowledge already finding and fixing some (easy-to-fix) regressions from the above work. If you migrate to WGPU 22 and encounter such bugs, please engage us in the issue tracker right away!
`wgpu::RenderPass`&`wgpu::ComputePass` recording methods (e.g. `wgpu::RenderPass:set_render_pipeline`) no longer impose a lifetime constraint to objects passed to a pass (like pipelines/buffers/bindgroups/query-sets etc.).
This means the following pattern works now as expected:
Furthermore, you can now opt out of `wgpu::RenderPass`/`wgpu::ComputePass`'s lifetime dependency on its parent `wgpu::CommandEncoder` using `wgpu::RenderPass::forget_lifetime`/`wgpu::ComputePass::forget_lifetime`:
⚠️ As long as a `wgpu::RenderPass`/`wgpu::ComputePass` is pending for a given `wgpu::CommandEncoder`, creation of a compute or render pass is an error and invalidates the `wgpu::CommandEncoder`.
`forget_lifetime` can be very useful for library authors, but opens up an easy way for incorrect use, so use with care.
This method doesn't add any additional overhead and has no side effects on pass recording.
By @wumpf in [#5569](https://github.com/gfx-rs/wgpu/pull/5569), [#5575](https://github.com/gfx-rs/wgpu/pull/5575), [#5620](https://github.com/gfx-rs/wgpu/pull/5620), [#5768](https://github.com/gfx-rs/wgpu/pull/5768) (together with @kpreid), [#5671](https://github.com/gfx-rs/wgpu/pull/5671), [#5794](https://github.com/gfx-rs/wgpu/pull/5794), [#5884](https://github.com/gfx-rs/wgpu/pull/5884).
- Added memory allocation hints to `DeviceDescriptor` by @nical in [#5875](https://github.com/gfx-rs/wgpu/pull/5875)
-`MemoryHints::Performance`, the default, favors performance over memory usage and will likely cause large amounts of VRAM to be allocated up-front. This hint is typically good for games.
-`MemoryHints::MemoryUsage` favors memory usage over performance. This hint is typically useful for smaller applications or UI libraries.
-`MemoryHints::Manual` allows the user to specify parameters for the underlying GPU memory allocator. These parameters are subject to change.
- These hints may be ignored by some backends. Currently only the Vulkan and D3D12 backends take them into account.
- Added type upgrades to SPIR-V atomic support. Added related infrastructure. Tracking issue is [here](https://github.com/gfx-rs/wgpu/issues/4489). By @schell in [#5775](https://github.com/gfx-rs/wgpu/pull/5775).
- Began work adding support for atomics to the SPIR-V frontend. Tracking issue is [here](https://github.com/gfx-rs/wgpu/issues/4489). By @schell in [#5702](https://github.com/gfx-rs/wgpu/pull/5702).
- In hlsl-out, allow passing information about the fragment entry point to omit vertex outputs that are not in the fragment inputs. By @Imberflur in [#5531](https://github.com/gfx-rs/wgpu/pull/5531)
- HLSL & MSL output can now be added conditionally on the target via the `msl-out-if-target-apple` and `hlsl-out-if-target-windows` features. This is used in wgpu-hal to no longer compile with MSL output when `metal` is enabled & MacOS isn't targeted and no longer compile with HLSL output when `dx12` is enabled & Windows isn't targeted. By @wumpf in [#5919](https://github.com/gfx-rs/wgpu/pull/5919)
#### Vulkan
- Added a `PipelineCache` resource to allow using Vulkan pipeline caches. By @DJMcNab in [#5319](https://github.com/gfx-rs/wgpu/pull/5319)
- Unconsumed vertex outputs are now always allowed. Removed `StageError::InputNotConsumed`, `Features::SHADER_UNUSED_VERTEX_OUTPUT`, and associated validation. By @Imberflur in [#5531](https://github.com/gfx-rs/wgpu/pull/5531)
-`wgpu::Error` is now `Sync`, making it possible to be wrapped in `anyhow::Error` or `eyre::Report`. By @nolanderc in [#5820](https://github.com/gfx-rs/wgpu/pull/5820)
- Added benchmark suite. By @cwfitzgerald in [#5694](https://github.com/gfx-rs/wgpu/pull/5694), compute passes by @wumpf in [#5767](https://github.com/gfx-rs/wgpu/pull/5767)
-`wgpu::ComputePass` now internally takes ownership of `QuerySet` for both `wgpu::ComputePassTimestampWrites` as well as timestamp writes and statistics query, fixing crashes when destroying `QuerySet` before ending the pass. By @wumpf in [#5671](https://github.com/gfx-rs/wgpu/pull/5671)
- Fix `ClearColorF`, `ClearColorU` and `ClearColorI` commands being issued before `SetDrawColorBuffers` [#5666](https://github.com/gfx-rs/wgpu/pull/5666)
- Replace `glClear` with `glClearBufferF` because `glDrawBuffers` requires that the ith buffer must be `COLOR_ATTACHMENTi` or `NONE` [#5666](https://github.com/gfx-rs/wgpu/pull/5666)
- Return the unmodified version in driver_info. By @Valaphee in [#5753](https://github.com/gfx-rs/wgpu/pull/5753)
#### Naga
- In spv-out don't decorate a `BindingArray`'s type with `Block` if the type is a struct with a runtime array by @Vecvec in [#5776](https://github.com/gfx-rs/wgpu/pull/5776)
- Add `packed` as a keyword for GLSL by @kjarosh in [#5855](https://github.com/gfx-rs/wgpu/pull/5855)
## v0.20.2 (2024-06-12)
This release force-bumps transitive dependencies of `wgpu` on `wgpu-core` and `wgpu-hal` to 0.21.1, to resolve some undefined behavior observable in the DX12 backend after upgrading to Rust 1.79 or later.
### Bug Fixes
#### General
* Fix a `CommandBuffer` leak. By @cwfitzgerald and @nical in [#5141](https://github.com/gfx-rs/wgpu/pull/5141)
* Do not feed `&""` to `D3DCompile`, by @workingjubilee in [#5812](https://github.com/gfx-rs/wgpu/issues/5812).
## v0.20.1 (2024-06-12)
This release included v0.21.0 of `wgpu-core` and `wgpu-hal`, due to breaking changes needed to solve vulkan validation issues.
### Bug Fixes
This release fixes the validation errors whenever a surface is used with the vulkan backend. By @cwfitzgerald in [#5681](https://github.com/gfx-rs/wgpu/pull/5681).
#### General
- Clean up weak references to texture views and bind groups to prevent memory leaks. By @xiaopengli89 in [#5595](https://github.com/gfx-rs/wgpu/pull/5595).
- Fix segfault on exit is queue & device are dropped before surface. By @sagudev in [#5640](https://github.com/gfx-rs/wgpu/pull/5640).
- Fix enablement of subgroup ops extension on Vulkan devices that don't support Vulkan 1.3. By @cwfitzgerald in [#5624](https://github.com/gfx-rs/wgpu/pull/5624).
- Work around shader consumers that have bugs handling `switch` statements with a single body for all cases. These are now written as `do {} while(false);` loops in hlsl-out and glsl-out. By @Imberflur in [#5654](https://github.com/gfx-rs/wgpu/pull/5654)
- In hlsl-out, defer `continue` statements in switches by setting a flag and breaking from the switch. This allows such constructs to work with FXC which does not support `continue` within a switch. By @Imberflur in [#5654](https://github.com/gfx-rs/wgpu/pull/5654)
By @teoxoy&@jimblandy in [#5500](https://github.com/gfx-rs/wgpu/pull/5500)
#### Changed feature requirements for timestamps
Due to a specification change `write_timestamp` is no longer supported on WebGPU.
`wgpu::CommandEncoder::write_timestamp` requires now the new `wgpu::Features::TIMESTAMP_QUERY_INSIDE_ENCODERS` feature which is available on all native backends but not on WebGPU.
By @wumpf in [#5188](https://github.com/gfx-rs/wgpu/pull/5188)
#### Wgsl const evaluation for many more built-ins
Many numeric built-ins have had a constant evaluation implementation added for them, which allows them to be used in a `const` context:
Availability is governed by the following feature flags:
*`wgpu::Features::SUBGROUP` for all operations except `subgroupBarrier` in fragment & compute, supported on Vulkan, DX12 and Metal.
*`wgpu::Features::SUBGROUP_VERTEX`, for all operations except `subgroupBarrier` general operations in vertex shaders, supported on Vulkan
*`wgpu::Features::SUBGROUP_BARRIER`, for support of the `subgroupBarrier` operation, supported on Vulkan & Metal
Note that there currently [some differences](https://github.com/gfx-rs/wgpu/issues/5555) between wgpu's native-only implementation and the [open WebGPU proposal](https://github.com/gpuweb/gpuweb/blob/main/proposals/subgroups.md).
By @exrook and @lichtso in [#5301](https://github.com/gfx-rs/wgpu/pull/5301)
##### Signed and unsigned 64 bit integer support in shaders.
`wgpu::Features::SHADER_INT64` enables 64 bit integer signed and unsigned integer variables in wgsl (`i64` and `u64` respectively).
Supported on Vulkan, DX12 (requires DXC) and Metal (with MSL 2.3+ support).
-`wgpu-types`'s `trace` and `replay` features have been replaced by the `serde` feature. By @KirmesBude in [#5149](https://github.com/gfx-rs/wgpu/pull/5149)
-`wgpu-core`'s `serial-pass` feature has been removed. Use `serde` instead. By @KirmesBude in [#5149](https://github.com/gfx-rs/wgpu/pull/5149)
- Added `InstanceFlags::GPU_BASED_VALIDATION`, which enables GPU-based validation for shaders. This is currently only supported on the DX12 and Vulkan backends; other platforms ignore this flag, for now. By @ErichDonGubler in [#5146](https://github.com/gfx-rs/wgpu/pull/5146), [#5046](https://github.com/gfx-rs/wgpu/pull/5046).
- This has been added to the set of flags set by `InstanceFlags::advanced_debugging`. Since the overhead is potentially very large, the flag is not enabled by default in debug builds when using `InstanceFlags::from_build_config`.
- As with other instance flags, this flag can be changed in calls to `InstanceFlags::with_env` with the new `WGPU_GPU_BASED_VALIDATION` environment variable.
-`wgpu::Instance` can now report which `wgpu::Backends` are available based on the build configuration. By @wumpf [#5167](https://github.com/gfx-rs/wgpu/pull/5167)
- Breaking change: [`wgpu_core::pipeline::ProgrammableStageDescriptor`](https://docs.rs/wgpu-core/latest/wgpu_core/pipeline/struct.ProgrammableStageDescriptor.html#structfield.entry_point) is now optional. By @ErichDonGubler in [#5305](https://github.com/gfx-rs/wgpu/pull/5305).
- Breaking change: [`wgpu_core::pipeline::ShaderError`](https://docs.rs/wgpu-core/latest/wgpu_core/pipeline/struct.ShaderError.html) has been moved to `naga`. By @stefnotch in [#5410](https://github.com/gfx-rs/wgpu/pull/5410)
- Allow user to select which MSL version to use via `--metal-version` with Naga CLI. By @pcleavelin in [#5392](https://github.com/gfx-rs/wgpu/pull/5392)

- OpenGL will now be preferred over OpenGL ES on EGL, making it consistent with WGL. By @valaphee in [#5482](https://github.com/gfx-rs/wgpu/pull/5482)
- Fill out `driver` and `driver_info`, with the OpenGL flavor and version, similar to Vulkan. By @valaphee in [#5482](https://github.com/gfx-rs/wgpu/pull/5482)
- Add mention of primitive restart in the description of `PrimitiveState::strip_index_format`. By @cpsdqs in [#5350](https://github.com/gfx-rs/wgpu/pull/5350)
- Document and tweak precise behaviour of `SourceLocation`. By @stefnotch in [#5386](https://github.com/gfx-rs/wgpu/pull/5386) and [#5410](https://github.com/gfx-rs/wgpu/pull/5410)

- Fix the validation of vertex and index ranges. By @nical in [#5144](https://github.com/gfx-rs/wgpu/pull/5144) and [#5156](https://github.com/gfx-rs/wgpu/pull/5156)
- Remove exposed C symbols (`extern "C"` + [no_mangle]) from RenderPass & ComputePass recording. By @wumpf in [#5409](https://github.com/gfx-rs/wgpu/pull/5409).
- Fix surfaces being only compatible with first backend enabled on an instance, causing failures when manually specifying an adapter. By @Wumpf in [#5535](https://github.com/gfx-rs/wgpu/pull/5535).
- In spv-in, remove unnecessary "gl_PerVertex" name check so unused builtins will always be skipped. Prevents validation errors caused by capability requirements of these builtins [#4915](https://github.com/gfx-rs/wgpu/issues/4915). By @Imberflur in [#5227](https://github.com/gfx-rs/wgpu/pull/5227).
- In spv-out, check for acceleration and ray-query types when enabling ray-query extension to prevent validation error. By @Vecvec in [#5463](https://github.com/gfx-rs/wgpu/pull/5463)
- Add a limit for curly brace nesting in WGSL parsing, plus a note about stack size requirements. By @ErichDonGubler in [#5447](https://github.com/gfx-rs/wgpu/pull/5447).
- In hlsl-out, fix accesses on zero value expressions by generating helper functions for `Expression::ZeroValue`. By @Imberflur in [#5587](https://github.com/gfx-rs/wgpu/pull/5587).
- Fix behavior of `extractBits` and `insertBits` when `offset + count` overflows the bit width. By @cwfitzgerald in [#5305](https://github.com/gfx-rs/wgpu/pull/5305)
- Fix behavior of integer `clamp` when `min` argument > `max` argument. By @cwfitzgerald in [#5300](https://github.com/gfx-rs/wgpu/pull/5300).
- Fix `TypeInner::scalar_width` to be consistent with the rest of the codebase and return values in bytes not bits. By @atlv24 in [#5532](https://github.com/gfx-rs/wgpu/pull/5532).
- Fix `first_instance` getting ignored in draw indexed when `ARB_shader_draw_parameters` feature is present and `base_vertex` is 0. By @valaphee in [#5482](https://github.com/gfx-rs/wgpu/pull/5482)
- Set object labels when the DEBUG flag is set, even if the VALIDATION flag is disabled. By @DJMcNab in [#5345](https://github.com/gfx-rs/wgpu/pull/5345).
- Add safety check to `wgpu_hal::vulkan::CommandEncoder` to make sure `discard_encoding` is not called in the closed state. By @villuna in [#5557](https://github.com/gfx-rs/wgpu/pull/5557)

This release only releases `wgpu-hal` 0.19.5, which contains an important fix
for DX12.
### Bug Fixes
#### DX12
- Do not feed `&""` to `D3DCompile`, by @workingjubilee in [#5812](https://github.com/gfx-rs/wgpu/issues/5812), backported by @Elabajaba in [#5833](https://github.com/gfx-rs/wgpu/pull/5833).
- Don't depend on bind group and bind group layout entry order in backends. This caused incorrect severely incorrect command execution and, in some cases, crashes. By @ErichDonGubler in [#5421](https://github.com/gfx-rs/wgpu/pull/5421).
- Properly clean up all write_buffer/texture temporary resources. By @robtfm in [#5413](https://github.com/gfx-rs/wgpu/pull/5413).
- Fix deadlock in certain situations when mapping buffers using `wgpu-profiler`. By @cwfitzgerald in [#5517](https://github.com/gfx-rs/wgpu/pull/5517)
#### WebGPU
- Correctly pass through timestamp queries to WebGPU. By @cwfitzgerald in [#5527](https://github.com/gfx-rs/wgpu/pull/5527).
**`--cfg=web_sys_unstable_apis` is no longer needed in your `RUSTFLAGS` to compile for WebGPU!!!**
While WebGPU's javascript api is stable in the browsers, the `web_sys` bindings for WebGPU are still improving. As such they are hidden behind the special cfg `--cfg=web_sys_unstable_apis` and are not available by default. Everyone who wanted to use our WebGPU backend needed to enable this cfg in their `RUSTFLAGS`. This was very inconvenient and made it hard to use WebGPU, especially when WebGPU is enabled by default. Additionally, the unstable APIs don't adhere to semver, so there were repeated breakages.
To combat this problem we have decided to vendor the `web_sys` bindings for WebGPU within the crate. Notably we are not forking the bindings, merely vendoring, so any improvements we make to the bindings will be contributed directly to upstream `web_sys`.
By @cwfitzgerald in [#5325](https://github.com/gfx-rs/wgpu/pull/5325).

## v0.19.1 (2024-01-22)
This release includes `wgpu` and `wgpu-hal`. The rest of the crates are unchanged since 0.19.0.
### Bug Fixes

#### OpenGL
- In Surface::configure and Surface::present on Windows, fix the current GL context not being unset when releasing the lock that guards access to making the context current. This was causing other threads to panic when trying to make the context current. By @Imberflur in [#5087](https://github.com/gfx-rs/wgpu/pull/5087).
#### WebGPU
- Improve error message when compiling WebGPU backend on wasm without the `web_sys_unstable_apis` set. By @rukai in [#5104](https://github.com/gfx-rs/wgpu/pull/5104)
### Documentation
- Document Wayland specific behavior related to `SurfaceTexture::present`. By @i509VCB in [#5093](https://github.com/gfx-rs/wgpu/pull/5093).
The `naga-ir` feature has been added to allow you to add naga module shaders without guessing about what other features needed to be enabled to get access to it.
By @cwfitzgerald in [#5063](https://github.com/gfx-rs/wgpu/pull/5063).
This feature allowed you to call `global_id` on any wgpu opaque handle to get a unique hashable identity for the given resource. This is now available without the feature flag.
By @cwfitzgerald in [#4841](https://github.com/gfx-rs/wgpu/pull/4841).
wgpu now exposes backend feature for the Direct3D 12 (`dx12`) and Metal (`metal`) backend. These are enabled by default, but don't do anything when not targeting the corresponding OS.
By @daxpedda in [#4815](https://github.com/gfx-rs/wgpu/pull/4815).
This backend had no functionality, and with the recent support for GL on Desktop, which allows wgpu to run on older devices, there was no need to keep this backend.
By @valaphee in [#4828](https://github.com/gfx-rs/wgpu/pull/4828).
This adds a way to allow a Vulkan driver which is non-compliant per `VK_KHR_driver_properties` to be enumerated. This is intended for testing new Vulkan drivers which are not Vulkan compliant yet.
By @i509VCB in [#4754](https://github.com/gfx-rs/wgpu/pull/4754).
Previously, `DeviceExt::create_texture_with_data` only allowed data to be provided in layer major order. There is now a `order` parameter which allows you to specify if the data is in layer major or mip major order.
All possible safe variants (owned windows and web canvases) are grouped using `wgpu::SurfaceTarget`.
Conversion to `wgpu::SurfaceTarget` is automatic for any type implementing `raw-window-handle`'s `HasWindowHandle`&`HasDisplayHandle` traits, i.e. most window types.
For web canvas types this has to be done explicitly:
```rust
let surface: wgpu::Surface<'static> = instance.create_surface(wgpu::SurfaceTarget::Canvas(my_canvas))?;
- Added `DownlevelFlags::VERTEX_AND_INSTANCE_INDEX_RESPECTS_RESPECTIVE_FIRST_VALUE_IN_INDIRECT_DRAW` to know if `@builtin(vertex_index)` and `@builtin(instance_index)` will respect the `first_vertex` / `first_instance` in indirect calls. If this is not present, both will always start counting from 0. Currently enabled on all backends except DX12. By @cwfitzgerald in [#4722](https://github.com/gfx-rs/wgpu/pull/4722).
- Added support for the `FLOAT32_FILTERABLE` feature (web and native, corresponds to WebGPU's `float32-filterable`). By @almarklein in [#4759](https://github.com/gfx-rs/wgpu/pull/4759).
- GPU buffer memory is released during "lose the device". By @bradwerth in [#4851](https://github.com/gfx-rs/wgpu/pull/4851).
- wgpu and wgpu-core cargo feature flags are now documented on docs.rs. By @wumpf in [#4886](https://github.com/gfx-rs/wgpu/pull/4886).
- DeviceLostClosure is guaranteed to be invoked exactly once. By @bradwerth in [#4862](https://github.com/gfx-rs/wgpu/pull/4862).
- Log vulkan validation layer messages during instance creation and destruction: By @exrook in [#4586](https://github.com/gfx-rs/wgpu/pull/4586).
-`TextureFormat::block_size` is deprecated, use `TextureFormat::block_copy_size` instead: By @wumpf in [#4647](https://github.com/gfx-rs/wgpu/pull/4647).
- Rename of `DispatchIndirect`, `DrawIndexedIndirect`, and `DrawIndirect` types in the `wgpu::util` module to `DispatchIndirectArgs`, `DrawIndexedIndirectArgs`, and `DrawIndirectArgs`. By @cwfitzgerald in [#4723](https://github.com/gfx-rs/wgpu/pull/4723).
- Make the size parameter of `encoder.clear_buffer` an `Option<u64>` instead of `Option<NonZero<u64>>`. By @nical in [#4737](https://github.com/gfx-rs/wgpu/pull/4737).
- Reduce the `info` log level noise. By @nical in [#4769](https://github.com/gfx-rs/wgpu/pull/4769), [#4711](https://github.com/gfx-rs/wgpu/pull/4711) and [#4772](https://github.com/gfx-rs/wgpu/pull/4772)
- Rename `features`&`limits` fields of `DeviceDescriptor` to `required_features`&`required_limits`. By @teoxoy in [#4803](https://github.com/gfx-rs/wgpu/pull/4803).
-`SurfaceConfiguration` now exposes `desired_maximum_frame_latency` which was previously hard-coded to 2. By setting it to 1 you can reduce latency under the risk of making GPU & CPU work sequential. Currently, on DX12 this affects the `MaximumFrameLatency`, on all other backends except OpenGL the size of the swapchain (on OpenGL this has no effect). By @emilk&@wumpf in [#4899](https://github.com/gfx-rs/wgpu/pull/4899)
-`@builtin(instance_index)` now properly reflects the range provided in the draw call instead of always counting from 0. By @cwfitzgerald in [#4722](https://github.com/gfx-rs/wgpu/pull/4722).
- Desktop GL now supports `POLYGON_MODE_LINE` and `POLYGON_MODE_POINT`. By @valaphee in [#4836](https://github.com/gfx-rs/wgpu/pull/4836).
- Naga's WGSL front end now allows operators to produce values with abstract types, rather than concretizing their operands. By @jimblandy in [#4850](https://github.com/gfx-rs/wgpu/pull/4850) and [#4870](https://github.com/gfx-rs/wgpu/pull/4870).
- Naga's WGSL front and back ends now have experimental support for 64-bit floating-point literals: `1.0lf` denotes an `f64` value. There has been experimental support for an `f64` type for a while, but until now there was no syntax for writing literals with that type. As before, Naga module validation rejects `f64` values unless `naga::valid::Capabilities::FLOAT64` is requested. By @jimblandy in [#4747](https://github.com/gfx-rs/wgpu/pull/4747).
- Naga constant evaluation can now process binary operators whose operands are both vectors. By @jimblandy in [#4861](https://github.com/gfx-rs/wgpu/pull/4861).
- Add `--bulk-validate` option to Naga CLI. By @jimblandy in [#4871](https://github.com/gfx-rs/wgpu/pull/4871).
- Naga's `cargo xtask validate` now runs validation jobs in parallel, using the [jobserver](https://crates.io/crates/jobserver) protocol to limit concurrency, and offers a `validate all` subcommand, which runs all available validation types. By @jimblandy in [#4902](https://github.com/gfx-rs/wgpu/pull/4902).
- Remove `span` and `validate` features. Always fully validate shader modules, and always track source positions for use in error messages. By @teoxoy in [#4706](https://github.com/gfx-rs/wgpu/pull/4706).
- Introduce a new `Scalar` struct type for use in Naga's IR, and update all frontend, middle, and backend code appropriately. By @jimblandy in [#4673](https://github.com/gfx-rs/wgpu/pull/4673).
- Add more metal keywords. By @fornwall in [#4707](https://github.com/gfx-rs/wgpu/pull/4707).
- Add a new `naga::Literal` variant, `I64`, for signed 64-bit literals. [#4711](https://github.com/gfx-rs/wgpu/pull/4711).
-`BufferMappedRange` trait is now `WasmNotSendSync`, i.e. it is `Send`/`Sync` if not on wasm or `fragile-send-sync-non-atomic-wasm` is enabled. By @wumpf in [#4818](https://github.com/gfx-rs/wgpu/pull/4818).
- Align `wgpu_types::CompositeAlphaMode` serde serialization to spec. By @littledivy in [#4940](https://github.com/gfx-rs/wgpu/pull/4940).
- Fix error message of `ConfigureSurfaceError::TooLarge`. By @Dinnerbone in [#4960](https://github.com/gfx-rs/wgpu/pull/4960).
- Fix dropping of `DeviceLostCallbackC` params. By @bradwerth in [#5032](https://github.com/gfx-rs/wgpu/pull/5032).
- Fixed a number of panics. By @nical in [#4999](https://github.com/gfx-rs/wgpu/pull/4999), [#5014](https://github.com/gfx-rs/wgpu/pull/5014), [#5024](https://github.com/gfx-rs/wgpu/pull/5024), [#5025](https://github.com/gfx-rs/wgpu/pull/5025), [#5026](https://github.com/gfx-rs/wgpu/pull/5026), [#5027](https://github.com/gfx-rs/wgpu/pull/5027), [#5028](https://github.com/gfx-rs/wgpu/pull/5028) and [#5042](https://github.com/gfx-rs/wgpu/pull/5042).
- No longer validate surfaces against their allowed extent range on configure. This caused warnings that were almost impossible to avoid. As before, the resulting behavior depends on the compositor. By @wumpf in [#4796](https://github.com/gfx-rs/wgpu/pull/4796).
- Fixed D3D12_SUBRESOURCE_FOOTPRINT calculation for block compressed textures which caused a crash with `Queue::write_texture` on DX12. By @DTZxPorter in [#4990](https://github.com/gfx-rs/wgpu/pull/4990).
- Allow calling `BufferSlice::get_mapped_range` multiple times on the same buffer slice (instead of throwing a Javascript exception). By @DouglasDwyer in [#4726](https://github.com/gfx-rs/wgpu/pull/4726).
- Make module compaction preserve the module's named types, even if they are unused. By @jimblandy in [#4734](https://github.com/gfx-rs/wgpu/pull/4734).
- When reading GLSL, fix the argument types of the double-precision floating-point overloads of the `dot`, `reflect`, `distance`, and `ldexp` builtin functions. Correct the WGSL generated for constructing 64-bit floating-point matrices. Add tests for all the above. By @jimblandy in [#4684](https://github.com/gfx-rs/wgpu/pull/4684).
- Allow Naga's IR types to represent matrices with elements elements of any scalar kind. This makes it possible for Naga IR types to represent WGSL abstract matrices. By @jimblandy in [#4735](https://github.com/gfx-rs/wgpu/pull/4735).
- Preserve the source spans for constants and expressions correctly across module compaction. By @jimblandy in [#4696](https://github.com/gfx-rs/wgpu/pull/4696).
- remove winit dependency from hello-compute example. By @psvri in [#4699](https://github.com/gfx-rs/wgpu/pull/4699)
- hello-compute example fix failure with `wgpu error: Validation Error` if arguments are missing. By @vilcans in [#4939](https://github.com/gfx-rs/wgpu/pull/4939).
- Made the examples page not crash on Chrome on Android, and responsive to screen sizes. By @Dinnerbone in [#4958](https://github.com/gfx-rs/wgpu/pull/4958).
## v0.18.2 (2023-12-06)
This release includes `naga` version 0.14.2. The crates `wgpu-core`, `wgpu-hal` are still at `0.18.1` and the crates `wgpu` and `wgpu-types` are still at `0.18.0`.
### Bug Fixes
#### Naga
- When evaluating const-expressions and generating SPIR-V, properly handle `Compose` expressions whose operands are `Splat` expressions. Such expressions are created and marked as constant by the constant evaluator. By @jimblandy in [#4695](https://github.com/gfx-rs/wgpu/pull/4695).
- Always use HLSL 2018 when using DXC to compile HLSL shaders. By @daxpedda in [#4629](https://github.com/gfx-rs/wgpu/pull/4629)
#### Metal
- In Metal Shading Language output, fix issue where local variables were sometimes using variable names from previous functions. By @DJMcNab in [#4594](https://github.com/gfx-rs/wgpu/pull/4594)
We now support OpenGL on Windows! This brings support for a vast majority of the hardware that used to be covered by our DX11 backend. As of this writing we support OpenGL 3.3+, though there are efforts to reduce that further.
This allows us to cover the last 12 years of Intel GPUs (starting with Ivy Bridge; aka 3xxx), and the last 16 years of AMD (starting with Terascale; aka HD 2000) / NVidia GPUs (starting with Tesla; aka GeForce 8xxx).
### Timestamp Queries Supported on Metal and OpenGL
Timestamp queries are now supported on both Metal and Desktop OpenGL. On Apple chips on Metal, they only support timestamp queries in command buffers or in the renderpass descriptor,
Addition of the `TimestampWrites` type to compute and render pass descriptors to allow profiling on tilers which do not support timestamps inside passes.
`flags` allow you to toggle the underlying api validation layers, debug information about shaders and objects in capture programs, and the ability to discard labels
`gles_minor_version` is a rather niche feature that allows you to force the GLES backend to use a specific minor version, this is useful to get ANGLE to enable more than GLES 3.0.

let instance = wgpu::Instance::new(InstanceDescriptor {
Our testing harness was completely revamped and now automatically runs against all gpus in the system, shows the expected status of every test, and is tolerant to flakes.
Additionally, we have filled out our CI to now run the latest versions of WARP and Mesa. This means we can test even more features on CI than before.

## v0.17.1 (2023-09-27)
### Added/New Features
- Add `get_mapped_range_as_array_buffer` for faster buffer read-backs in wasm builds. By @ryankaplan in [#4042] (https://github.com/gfx-rs/wgpu/pull/4042).
### Bug Fixes
#### DX12
- Fix panic on resize when using DX12. By @cwfitzgerald in [#4106](https://github.com/gfx-rs/wgpu/pull/4106)
#### Vulkan
- Suppress validation error caused by OBS layer. This was also fixed upstream. By @cwfitzgerald in [#4002](https://github.com/gfx-rs/wgpu/pull/4002)
- Work around bug in nvidia's vkCmdFillBuffer implementation. By @cwfitzgerald in [#4132](https://github.com/gfx-rs/wgpu/pull/4132).
This is the first release that featured `wgpu-info` as a binary crate for getting information about what devices wgpu sees in your system. It can dump the information in both human readable format and json.
Up until this point, wgpu has made the assumption that threads do not exist on wasm. With the rise of libraries like [`wasm_thread`](https://crates.io/crates/wasm_thread) making it easier and easier to do wasm multithreading this assumption is no longer sound. As all wgpu objects contain references into the JS heap, they cannot leave the thread they started on.
As we understand that this change might be very inconvenient for users who don't care about wasm threading, there is a crate feature which re-enables the old behavior: `fragile-send-sync-non-atomic-wasm`. So long as you don't compile your code with `-Ctarget-feature=+atomics`, `Send` and `Sync` will be implemented again on wgpu types on wasm. As the name implies, especially for libraries, this is very fragile, as you don't know if a user will want to compile with atomics (and therefore threads) or not.
By @daxpedda in [#3691](https://github.com/gfx-rs/wgpu/pull/3691)
#### Power Preference is now optional
The `power_preference` field of `RequestAdapterOptions` is now optional. If it is `PowerPreference::None`, we will choose the first available adapter, preferring GPU adapters over CPU adapters.
By @Aaron1011 in [#3903](https://github.com/gfx-rs/wgpu/pull/3903)
Removed the backend_bits parameter from `initialize_adapter_from_env` and `initialize_adapter_from_env_or_default`. If you want to limit the backends used by this function, only enable the wanted backends in the instance.
- Added support for importing external buffers using `buffer_from_raw` (Dx12, Metal, Vulkan) and `create_buffer_from_hal`. By @AdrianEddy in [#3355](https://github.com/gfx-rs/wgpu/pull/3355)
- Work around [Vulkan-ValidationLayers#5671](https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/5671) by ignoring reports of violations of [VUID-vkCmdEndDebugUtilsLabelEXT-commandBuffer-01912](https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#VUID-vkCmdEndDebugUtilsLabelEXT-commandBuffer-01912).

- Fix enabling `wgpu::Features::PARTIALLY_BOUND_BINDING_ARRAY` not being actually enabled in vulkan backend. By @39ali in[#3772](https://github.com/gfx-rs/wgpu/pull/3772).
- Make the `Id` type that is exposed when using the `expose-ids` feature implement `Send` and `Sync` again. This was unintentionally changed by the v0.16.0 release and is now fixed.
- Increase the `max_storage_buffers_per_shader_stage` and `max_storage_textures_per_shader_stage` limits based on what the hardware supports. by @Elabajaba in [#3798]https://github.com/gfx-rs/wgpu/pull/3798
The `TextureFormat::describe` function was removed in favor of separate functions: `block_dimensions`, `is_compressed`, `is_srgb`, `required_features`, `guaranteed_format_features`, `sample_type` and `block_size`.
Buffers used as the `destination` argument of `CommandEncoder::resolve_query_set` now have to contain the `QUERY_RESOLVE` usage instead of the `COPY_DST` usage.
```diff
let destination = device.create_buffer(&wgpu::BufferDescriptor {
- Change type of `mip_level_count` and `array_layer_count` (members of `TextureViewDescriptor` and `ImageSubresourceRange`) from `Option<NonZeroU32>` to `Option<u32>`. By @teoxoy in [#3445](https://github.com/gfx-rs/wgpu/pull/3445)

- Fix handling of `None` values for `depth_ops` and `stencil_ops` in `RenderPassDescriptor::depth_stencil_attachment`. By @niklaskorz in [#3660](https://github.com/gfx-rs/wgpu/pull/3660)
- Fix `copy_external_image_to_texture`, `copy_texture_to_texture` and `copy_buffer_to_texture` not taking the specified index into account if the target texture is a cube map, 2D texture array or cube map array. By @daxpedda [#3641](https://github.com/gfx-rs/wgpu/pull/3641)

## v0.15.3 (2023-03-22)
### Bug Fixes
#### Metal
- Fix incorrect mipmap being sampled when using `MinLod <= 0.0` and `MaxLod >= 32.0` or when the fragment shader samples different Lods in the same quad. By @cwfitzgerald in [#3610](https://github.com/gfx-rs/wgpu/pull/3610).
#### GLES
- Fix `Vertex buffer is not big enough for the draw call.` for ANGLE/Web when rendering with instance attributes on a single instance. By @wumpf in [#3596](https://github.com/gfx-rs/wgpu/pull/3596)
- Enable `WEBGL_debug_renderer_info` before querying unmasked vendor/renderer to avoid crashing on emscripten in [#3519](https://github.com/gfx-rs/wgpu/pull/3519)
`Instance::create_surface()` now returns `Result<Surface, CreateSurfaceError>` instead of `Surface`. This allows an error to be returned if the given window is a HTML canvas and obtaining a WebGPU or WebGL 2 context fails. (No other platforms currently report any errors through this path.) By @kpreid in [#3052](https://github.com/gfx-rs/wgpu/pull/3052/)
A new api, `Queue::copy_external_image_to_texture`, allows you to create wgpu textures from various web image primitives. Specifically from `HtmlVideoElement`, `HtmlCanvasElement`, `OffscreenCanvas`, and `ImageBitmap`. This provides multiple low-copy ways of interacting with the browser. WebGL is also supported, though WebGL has some additional restrictions, represented by the `UNRESTRICTED_EXTERNAL_IMAGE_COPIES` downlevel flag. By @cwfitzgerald in [#3288](https://github.com/gfx-rs/wgpu/pull/3288)
`Instance::new()` and `hub::Global::new()` now take an `InstanceDescriptor` struct which contains both the existing `Backends` selection as well as a new `Dx12Compiler` field for selecting which Dx12 shader compiler to use.
The new `view_formats` field in the `TextureDescriptor` is used to specify a list of formats the texture can be re-interpreted to in a texture view. Currently only changing srgb-ness is allowed (ex. `Rgba8Unorm`<=> `Rgba8UnormSrgb`).
Via the `TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES` feature, MSAA x2 and x8 are now supported on textures. To query for x2 or x8 support, enable the feature and look at the texture format flags for the texture format of your choice.
By @39ali in [3140](https://github.com/gfx-rs/wgpu/pull/3140)
#### DXC Shader Compiler Support for DX12
You can now choose to use the DXC compiler for DX12 instead of FXC. The DXC compiler is faster, less buggy, and allows for new features compared to the old, unmaintained FXC compiler.
You can choose which compiler to use at `Instance` creation using the `dx12_shader_compiler` field in the `InstanceDescriptor` struct. Note that DXC requires both `dxcompiler.dll` and `dxil.dll`, which can be downloaded from https://github.com/microsoft/DirectXShaderCompiler/releases. Both .dlls need to be shipped with your application when targeting DX12 and using the `DXC` compiler. If the .dlls can't be loaded, then it will fall back to the FXC compiler. By @39ali and @Elabajaba in [#3356](https://github.com/gfx-rs/wgpu/pull/3356)
The DX12 backend can now suballocate buffers and textures from larger chunks of memory, which can give a significant increase in performance (in testing a 100x improvement has been seen in a simple scene with 200 `write_buffer` calls per frame, and a 1.4x improvement in [Bistro using Bevy](https://github.com/vleue/bevy_bistro_playground)).
Previously `wgpu-hal`'s DX12 backend created a new heap on the GPU every time you called `write_buffer` (by calling `CreateCommittedResource`), whereas now it uses [`gpu_allocator`](https://crates.io/crates/gpu-allocator) to manage GPU memory (and calls `CreatePlacedResource` with a suballocated heap). By @Elabajaba in [#3163](https://github.com/gfx-rs/wgpu/pull/3163)
#### Backend selection by features in wgpu-core
Whereas `wgpu-core` used to automatically select backends to enable
based on the target OS and architecture, it now has separate features
to enable each backend:
- "metal", for the Metal API on macOS and iOS
- "vulkan", for the Vulkan API (Linux, some Android, and occasionally Windows)
- "dx12", for Microsoft's Direct3D 12 API
- "gles", OpenGL ES, available on many systems
- "dx11", for Microsoft's Direct3D 11 API
None are enabled by default, but the `wgpu` crate automatically
selects these features based on the target operating system and
architecture, using the same rules that `wgpu-core` used to, so users
of `wgpu` should be unaffected by this change. However, other crates
using `wgpu-core` directly will need to copy `wgpu`'s logic or write
their own. See the `[target]` section of `wgpu/Cargo.toml` for
details.
Similarly, `wgpu-core` now has `emscripten` and `renderdoc` features
that `wgpu` enables on appropriate platforms.
In previous releases, the `wgpu-core` crate decided which backends to
support. However, this left `wgpu-core`'s users with no way to
override those choices. (Firefox doesn't want the GLES back end, for
example.) There doesn't seem to be any way to have a crate select
backends based on target OS and architecture that users of that crate
can still override. Default features can't be selected based on the
target, for example. That implies that we should do the selection as
late in the dependency DAG as feasible. Having `wgpu` (and
`wgpu-core`'s other dependents) choose backends seems like the best
option.
By @jimblandy in [#3254](https://github.com/gfx-rs/wgpu/pull/3254).
- New downlevel feature `UNRESTRICTED_INDEX_BUFFER` to indicate support for using `INDEX` together with other non-copy/map usages (unsupported on WebGL). By @Wumpf in [#3157](https://github.com/gfx-rs/wgpu/pull/3157)
