Lataa Claude Code 2.1.108

- Added ENABLE_PROMPT_CACHING_1H env var to opt into 1-hour prompt cache TTL on API key, Bedrock, Vertex, and Foundry (ENABLE_PROMPT_CACHING_1H_BEDROCK is deprecated but still honored), and FORCE_PROMPT_CACHING_5M to force 5-minute TTL
- Added recap feature to provide context when returning to a session, configurable in /config and manually invocable with /recap; force with CLAUDE_CODE_ENABLE_AWAY_SUMMARY if telemetry disabled.
- The model can now discover and invoke built-in slash commands like /init, /review, and /security-review via the Skill tool
- /undo is now an alias for /rewind
- Improved /model to warn before switching models mid-conversation, since the next response re-reads the full history uncached
- Improved /resume picker to default to sessions from the current directory; press Ctrl+A to show all projects
- Improved error messages: server rate limits are now distinguished from plan usage limits; 5xx/529 errors show a link to status.claude.com; unknown slash commands suggest the closest match
- Reduced memory footprint for file reads, edits, and syntax highlighting by loading language grammars on demand
- Added "verbose" indicator when viewing the detailed transcript (Ctrl+O)
- Added a warning at startup when prompt caching is disabled via DISABLE_PROMPT_CACHING* environment variables
- Fixed paste not working in the /login code prompt (regression in 2.1.105)
- Fixed subscribers who set DISABLE_TELEMETRY falling back to 5-minute prompt cache TTL instead of 1 hour
- Fixed Agent tool prompting for permission in auto mode when the safety classifier's transcript exceeded its context window
- Fixed Bash tool producing no output when CLAUDE_ENV_FILE (e.g. ~/.zprofile) ends with a # comment line
- Fixed claude --resume <session-id> losing the session's custom name and color set via /rename
- Fixed session titles showing placeholder example text when the first message is a short greeting
- Fixed terminal escape codes appearing as garbage text in the prompt input after --teleport
- Fixed /feedback retry: pressing Enter to resubmit after a failure now works without first editing the description
- Fixed --teleport and --resume <id> precondition errors (e.g. dirty git tree, session not found) exiting silently instead of showing the error message
- Fixed Remote Control session titles set in the web UI being overwritten by auto-generated titles after the third message
- Fixed --resume truncating sessions when the transcript contained a self-referencing message
- Fixed transcript write failures (e.g., disk full) being silently dropped instead of being logged
- Fixed diacritical marks (accents, umlauts, cedillas) being dropped from responses when the language setting is configured
- Fixed policy-managed plugins never auto-updating when running from a different project than where they were first installed
