2026-07-02 engine changes

  • 1 PR merged Jul 1–2 — quiet day with a single crash fix landing in 0.19.1.
  • #24807 — Prevent panic in check_dir_light_mesh_visibility (dylansechet, merged by alice-i-cecile, A-Rendering, D-Straightforward, P-Crash, 0.19.1). Fixes #24804. A subtle Local<Parallel<...>> buffer resizing bug in directional-light shadow visibility checking caused out-of-bounds indexing when mesh counts dropped and cascade counts rose in the same frame. Fix: resize all per-thread buffers before the parallel loop.

Gap update — 150 PRs merged across 16 days. Major milestones: 0.19.1 at 90.6% (imminent patch release), 0.20 at 57.6%. Key themes: wgpu 30, Solari v7, MeshUniform GPU allocation, bindless 2D, Feathers UI example migration (~30+ PRs), fallback fonts, rendering optimizations.

Architectural Milestones

  • #23662 — Move MeshUniform allocation from CPU to GPU (pcwalton, merged Jul 7). Major rendering architecture change. Mesh uniform data is now allocated directly on the GPU via AtomicSparseBufferVec, reducing CPU overhead.

Bulk UI/Feathers Migration

~30+ PRs from kfc35, taearls, and others migrating Bevy examples from legacy ui::widget::Button to Feathers UI widgets and bsn! syntax. This is Phases 1-6 of a systematic example overhaul, indicating Feathers is becoming the default widget framework.
