Changes since last release

From CHANGELOG.md, 2026-10-30:

Upstream v4.4212.0

• Custom models re-fitted. The Code session's env builder is now a free function the buildSessionEnv method forwards to, with the base config one parameter further right; add_feature_custom_models sub-patch B finds the function through the method and splices cliEnv() there.
• "Load large sessions in full" keeps upstream's new history window. The session manager's limits now also carry historyWindowBytes, historyRequestBytes, historyScanChunkBytes and historyReadDeadlineMs. They belong to a paged history reader that nothing calls yet, so the feature still matters. The heavy-work worker's helper returned only our four sizes, which would have left those keys undefined in the worker once that reader is used; it now overrides the four sizes and keeps the rest, and add_feature_transcript_limits_worker matches the longer literal.
• Extra -> Deployment lists the new managed keys projectsEnabled, mcpAppWidgetsEnabled and sessionStatusLine (201 keys).
• --diagnose and --reset-screen-sharing stay bounded on Ubuntu 26.04. Its default timeout (uutils) sends a KILL to the direct child only, so a hung Computer Use bridge that left a child running made the launcher wait for that child. Bridge calls now time out with TERM followed by KILL a second later, which ends the whole process group with both GNU and uutils timeout.
• Audited: feature flags (672 -> 695; the one new Linux-facing gate, 1116624256, stops a bare Alt tap from opening the app menu on GNOME, matching upstream's release note), platform gates (no new macOS/Windows-only feature that Linux lacks), built-in MCP servers (no roster change), the ion-dist setup window (both ion patches apply unchanged) and the custom-models anchors. Electron stays 44.9.3, Claude Code 2.1.309.
