+![Spaceship](wgpu-spaceship.jpg)
+
+The community managed to squeeze the v0.7 releases out
+at the end of the month. See the detailed notes on [gfx blog post].
+
+The highlight of the show is about shaders. Most of wgpu-rs shaders are
+now written in [WGSL],
+and gfx-rs community is inviting Rust game/graphics developers to evaluate if
+[naga] could fulfill their shader translation needs in the future.
