Claude Code v2.1.193

  • OAuth profile: now requires both account and organization fields before applying a fetched profile; previously any non-null result was accepted, potentially leaving org context empty. (search for "l?.account && l.organization")
  • Bash parse error recovery: when the tree-sitter parser returns an ERROR node wrapping a program node at the root level, the inner program node is now unwrapped before redirect analysis, preventing false-positive dangerous-redirect detections. (search for "n.type === \"ERROR\" && n.children[0]?.type === \"program\"")
  • PowerShell quoting: shell-quoting checks on Windows now use the full Windows quoting rules (backslash at end of string requiring special treatment), not just dollar-sign detection. (search for "SCo(c)" in Windows quoting path)
  • Background bash shell memory pressure reaping: Claude Code now registers a memoryPressure event listener on background shell processes when not running as a subagent, allowing the OS to signal when memory is tight. Idle, unnoticed shells are then reaped. (search for "task_local_shell_pressure_reap")
  • MCP needs-auth count is now surfaced in the app state (mcpNeedsAuthCount), enabling the UI to reflect pending MCP authentication requirements. (search for "mcpNeedsAuthCount")
  • Model picker now correctly filters and replaces deprecated model aliases with their first-party equivalents when the model is confirmed available. (search for "Ia(r.aliasModel)" in model picker)
  • --mcp-debug flag removed; functionality is covered by --debug. (search for removed "--mcp-debug" in string diff)
  • Background agent spawn: when resuming a previous session with --resume, the transcript path is now correctly passed through to the background agent launch parameters. (search for "resumeTranscriptPath")
  • HTML content extraction: the web fetch tool now also extracts <meta name="description"> content and <h1> headings for better URL titles when the <title> tag is missing or generic. (search for "<meta[^>]+name=" in HTML parser)
  • Error telemetry: errors from background spawn failures and console method failures now include a telemetryMessage field (via gh()) so they're correctly categorized in error tracking rather than grouped under generic labels. (search for "background spawn failed" or "console.${s} failed")
