 ## Unreleased
-### Bug Fixes
-#### 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)
 
+## 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).
