Changes since last release

Upstream

• Version bump: v1.2278.0 → v1.2581.0
• New feature: coworkKappa — 19th feature flag added. Static entry sPn() always unavailable; async override aPn() depends on yukonSilver + GrowthBook flag 123929380. Gates a consolidate-memory skill ("Reflective pass over memory files — merge duplicates, fix stale facts, prune the index") and auto-memory directory for typeless sessions. Enabled on Linux — forced flag 123929380 to true (3 call sites) and added merger override. Purely local file I/O, no VM needed.
• Async merger jue now uses 3-way Promise.all([tPn(), Xsr(), aPn()]) (was 2-way) adding coworkKappa alongside louderPenguin and operon
• Function renames: eA()→iA() (static registry), yue→jue (async merger), CEe()→XEe() (gate function), Zr()→Yr() (flag reader)
• Platform variables renamed: vs→_s (win32), IOe→c3e (darwin||win32)
• 1 new GrowthBook boolean flag: 123929380 (coworkKappa / consolidate-memory skill)
• 1 removed GrowthBook flag: 4040257062 (memory path routing — was new in v1.1348.0)
• Same 6 MCP servers (Chrome, mcp-registry, office-addin, radar, visualize, computer-use)

Patches

• Fixed: fix_tray_dbus.py — tray variable pattern was too strict: used \w+ which can't match $ in JS identifiers (tray variable is now $m), and required }); immediately before let XX=null; but the event listener registration now sits in between. Changed to [\w$]+ and removed the \}\); prefix from the pattern.
• Enhanced: enable_local_agent_mode.py — added coworkKappa as 9th feature override in merger + bypassed GrowthBook flag 123929380 (3 call sites). Enables /consolidate-memory skill and auto-memory directory for sessions on Linux.
• All other 34 patches applied without modification — [\w$]+ regex patterns handled the renames automatically

ARM64 / Raspberry Pi 5

• ARM64 integrated terminal — node-pty is now cross-compiled for arm64 via Docker + QEMU in CI, replacing the old "strip x86_64 pty.node" workaround. All ARM64 packages (deb, rpm, AppImage) now include a working integrated terminal.
• New: scripts/rebuild-pty-for-arch.sh — reusable script for cross-compiling node-pty to any target architecture. Verifies the produced binary matches the target arch.
• Nix aarch64-linux — packaging/nix/package.nix now lists aarch64-linux in meta.platforms
• Raspberry Pi 5 — added to supported devices in README alongside DGX Spark and Jetson
• enable_local_agent_mode.py — added coworkKappa:{status:"supported"} to feature merger overrides and force-enabled GrowthBook flag 123929380 (consolidate-memory skill, auto-memory for typeless sessions)

Documentation

• CLAUDE_FEATURE_FLAGS.md — added coworkKappa (19th feature), updated all function names, added flag 123929380, removed flag 4040257062, version history entry
• CLAUDE_BUILT_IN_MCP.md — version number updated
• CHANGELOG.md — this entry
