New features
This RC is a patch-prep cut: no net-new product features beyond the fixes and reliability work below.
Fixes
- Too-wide alt-frame snapshot replay (#13014) — Skips oversized alt-screen frames so terminal snapshot replay does not corrupt the grid.
- Stale terminal selection on pane recovery (#13677) — Clears leftover selection when a terminal pane is recovered so copy/focus state stays correct.
- Windows PATH restore before shell changes (STA-3889) (#13792) — Restores Windows PATH ownership before shell profile changes rewrite the environment.
- Committed cloud artifact recovery (STA-3884) (#13796) — Recovers committed cloud artifact mutations after interrupted create/cleanup paths.
- First window before shell PATH hydration (STA-3886) (#13799) — Shows the first Windows window before shell PATH hydration so startup is not blocked on PATH work.
- Terminal link click ownership (STA-3888) (#13797) — Prevents link-action clicks from falling through to the child PTY/process.
- Claude Code quarter-circle spinners (#13925) — Treats Claude Code quarter-circle spinner glyphs as working so agent titles stay “busy” correctly.
- Preview Kitty IME / keyboard flags (STA-3887) (#13940) — Carries kitty keyboard flags and pairs IME releases through Design Preview terminals.
- Paired remote HTML browser ownership & focus (#13876) — Fixes paired remote HTML browser preview ownership, group placement, and focus so previews land in the right place without stealing focus incorrectly.
- WSL transcript fs gate (STA-3885) (#14090) — Gates WSL transcript filesystem ops with timeouts and capacity limits, and guards transcript-agent dispatch against silent OMP fallthrough (prevents stalled UNC/9P I/O from exhausting native-chat permits).
Reliability & performance
- WebGL atlas resets (#13657) — Removes output-driven WebGL atlas resets that caused unnecessary terminal GPU thrash.
- Federated orchestration reads (#13814) — Routes federated reads over shared control to cut orchestration fan-out cost.
