 ### MSRV policy
 
 Due to complex dependants, we have two MSRV policies:
- - `d3d12`, `naga`, `wgpu-core`, `wgpu-hal`, and `wgpu-types`'s MSRV is **1.65**.
+ - `d3d12`, `naga`, `wgpu-core`, `wgpu-hal`, and `wgpu-types`'s MSRV is **1.70**.
  - The rest of the workspace has an MSRV of **1.71**.
 
 It is enforced on CI (in "/.github/workflows/ci.yml") with the `CORE_MSRV` and `REPO_MSRV` variables.
