Auto-memory is now enabled by default in Claude Code, replacing the previous gradual rollout. Users can toggle it via /memory or configure it with the new autoMemoryEnabled setting.
The /copy command now shows an interactive picker when code blocks are present, allowing selection of individual code blocks or the full response.
Structured outputs now document property ordering behavior: required properties always appear before optional properties in output objects.
Multiple critical bug fixes in 2.1.59: MCP OAuth token refresh race condition, config file corruption, and missing error messages when the working directory is deleted.
Claude automatically saves useful context to auto-memory — manage with /memory
Added /copy command interactive picker: when code blocks are present, allows selection of individual code blocks or the full response
Existing feature improvements
Improved "always allow" prefix suggestions for compound bash commands (e.g. cd /tmp && git fetch && git push) to compute smarter per-subcommand prefixes instead of treating the whole command as one
Improved ordering of short task lists
Improved memory usage in multi-agent sessions by releasing completed subagent task state
Major bug fixes
Fixed MCP OAuth token refresh race condition when running multiple Claude Code instances simultaneously
Fixed shell commands not showing a clear error message when the working directory has been deleted
Fixed config file corruption that could wipe authentication when multiple Claude Code instances ran simultaneously
Updated /copy command description: now shows an interactive picker when code blocks are present, allowing selection of individual code blocks or the full response. [line ~100]
Auto-memory is now enabled by default (previously was rolling out gradually). [line ~31]
The /memory selector now includes an auto-memory toggle to turn the feature on or off. [line ~71]
New autoMemoryEnabled setting added to both user-level (~/.claude/settings.json) and project-level (.claude/settings.json) to control auto-memory. [lines ~73-90]
Documented that CLAUDE_CODE_DISABLE_AUTO_MEMORY environment variable takes precedence over both the toggle and settings.json, making it useful for CI/managed environments. [line ~95]
MCP server list reorganized with many entries reordered. New servers added: LSEG (financial data and analytics), MSCI (index data and analytics), and Common Room (contacts and accounts intelligence).
New "Property ordering" section added: documents that required properties always appear before optional properties in structured output objects, regardless of their order in the schema definition. Includes example schema and resulting output ordering. [lines ~401-445]
