# Change Log

## v0.5 (06-04-2020)
  - Crates:
    - `wgpu-types`: common types between native and web targets
    - `wgpu-core`: internal API for the native and remote wrappers
  - Features:
    - based on gfx-hal-0.5
    - moved from Rendy to the new `gfx-memory` and `gfx-descriptor` crates
    - passes are now recorded on the client side. The user is also responsible to keep all resources referenced in the pass up until it ends recording.
    - revised GPU lifetime tracking of all resources
    - revised usage tracking logic
    - all IDs are now non-zero
    - Mailbox present mode
  - Validation:
    - active pipeline
  - Fixes:
    - lots of small API changes to closely match upstream WebGPU
    - true read-only storage bindings
    - unmapping dropped buffers
    - better error messages on misused swapchain frames

## v0.4.3 (20-01-2020)
  - improved swap chain error handling

## v0.4.2 (15-12-2019)

## v0.3.3 (22-08-2019)
  - fixed instance creation on Windows

## v0.3.1 (21-08-2019)
  - fixed pipeline barriers that aren't transitions

## v0.3 (21-08-2019)

    - type-system-assisted deadlock prevention (for locking internal structures)
    - texture sub-resource tracking
    - `raw-window-handle` integration instead of `winit`
    - multisampling with an example

    - stencil masks and reference values
    - native "compute" example
    - everything implements `Debug`
  - Validation
    - vertex/index/instance ranges at draw calls
    - bing groups vs their expected layouts
    - bind group buffer ranges
    - required stencil reference, blend color

  - Crates:
    - `wgpu-remote`: remoting layer for the cross-process boundary
    - `gfx-examples`: selected gfx pre-ll examples ported over
  - Features:
    - native example for compute
    - "gfx-cube" and "gfx-shadow" examples
    - copies between buffers and textures
