 Due to complex dependants, we have two MSRV policies:
 
-- `naga`, `wgpu-core`, `wgpu-hal`, and `wgpu-types`'s MSRV is **1.76**, but may be lower than the rest of the workspace in the future.
-- The rest of the workspace has an MSRV of **1.83** as well right now, but may be higher than above listed crates.
+- `naga`, `wgpu-core`, `wgpu-hal`, and `wgpu-types`'s MSRV is **1.76**.
+- The rest of the workspace has an MSRV of **1.85**.
 
 It is enforced on CI (in "/.github/workflows/ci.yml") with the `CORE_MSRV` and `REPO_MSRV` variables.
 This version can only be upgraded in breaking releases, though we release a breaking version every three months.
