Released May 21, 2026. Everything the community has pinned to this exact release.
Eight days migrating a legacy widget suite to WidgetKit with Claude Code and XcodeBuild MCP: timeline budgets, a haunted pbxproj, and $84 of tokens.
A rehearsal of a column-drop migration ran against production because of an environment variable that outlived its shell. Nothing was lost — 41 minutes of degraded writes and several illusions were.
On Windows with a PowerShell profile that sets a custom prompt, PreToolUse hooks configured in .claude/settings.json silently never execute. No error, no log line — tool calls just proceed unguarded. Fixed in 2.4.0.
