AddedENABLE_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.
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
~changed 2
The model can now discover and invoke built-in slash commands like `/init`, `/review`, and `/security-review` via the Skill tool
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
Improvederror 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
