+
+Early this year, we made a decision to use the winit crate for window creation, as opposed to rolling our own.
+That work has now landed in main ([xilem#176] was the main PR, with a number of followups).
+A major motivation was to enable more platforms, with Android being a major goal.
+That work is in progress; a major subtask is enumerating the system fonts.
+As expected, this move has uncovered rough edges in winit and some regressions in behavior.
+We plan to address those, with the improvements hopefully benefiting the entire Rust UI ecosystem.
+
+The [Vello crate] has been published as version 0.1, with significant documentation improvements and a friendly example.
+We consider this an alpha-quality release, as there are known issues.
+Even so, we want to get a release out to facilitate integrations and shake out problems.
+
+Another major area of work on Vello is investigation of startup time, which can take multiple seconds when the platform's GPU drivers are slow at compiling the compute shaders.
+A number of techniques mitigate that.
+One is to compile shaders in parallel, using multiple cores, and that has landed ([vello#455]).
+An even bigger improvement will be caching compiled shaders.
+Daniel McNab has made an encouraging prototype ([vello#459]), and the ultimate goal is to land that in wgpu so projects across the ecosystem can benefit from it ([wgpu#5292]).
+
+The work to compute strokes on the GPU using Euler spirals continues, but has not yet landed.
+The current state is a draft PR that implements the logic in Rust code, which now needs to be translated to WGSL for GPU evaluation ([vello#496], draft PR).
+
+There has been progress at higher levels of Xilem.
+Among other things, Nico Burns landed a scroll view implementation ([xilem#155]), and Philipp Mildenberger has been steadily refining xilem_core and xilem_web, including fine grained tree structure tracking and minimal/efficient DOM-tree-updates ([xilem#160]).
