This feed tracks post-release changes to the Claude Code changelog. When Anthropic adds, modifies, or removes changelog entries after a version is released, those changes are detected and recorded here for transparency.
Fixed a permission you approved while a self-hosted runner was restarting being dropped when the session resumed, so the approved action now runs
Detected at 1:40 AM
Fixed a SIGTERM arriving while a self-hosted runner was starting up leaving a stale active row until the lease expired; it now deregisters cleanly
Detected at 1:40 AM
Added structured failure categories to self-hosted runner spawn and session failures, so hook errors, runner crashes and config errors can be told apart
Detected at 1:40 AM
Self-hosted runner: added a `post-session` lifecycle hook that runs after the session ends and before the workspace is deleted, so you can snapshot uncommitted work or export logs; also made the child-process SIGTERM→SIGKILL window configurable (default unchanged at 5s)
Detected at 1:40 AM
Added HTTP status and error text to `claude mcp list` and `/mcp` when a server fails to connect, and a warning for MCP config values with hidden leading or trailing whitespace
Detected at 5:30 PM
Changed the Fable 5 usage-credits consent prompt to start with the decline option focused
Detected at 5:05 PM
Added deprecation notification for npm installations - run `claude install` or see https://code.claude.com/docs/en/setup for more options

Subagents now run in the background by default, so Claude keeps working while they run and is notified when they finish (previously a gradual rollout)
Detected at 11:00 PM
Agent teams: removed the `TeamCreate` and `TeamDelete` tools. With `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1` set, every session now has one implicit team — spawn teammates directly with the Agent tool's `name` parameter, no setup step needed. The `team_name` parameter on the Agent tool is still accepted but ignored.
Detected at 10:05 PM

Detected at 3:20 AM

Detected at 6:30 AM
Claude can now reference the on-disk path of clipboard-pasted images for file operations

Detected at 1:16 AM
Improved `claude plugin validate` to explain that marketplace.json source paths are relative to the repo root when rejecting `../` paths
Detected at 1:16 AM
Reduced false-positive bash permission prompts — tree-sitter parsing now handles `find -exec`, variable assignments, command substitutions, and many other patterns that previously triggered unnecessary prompts. Also fixed tree-sitter not loading in npm-installed versions
Detected at 1:11 AM
Fixed config file corruption that could wipe authentication when multiple Claude Code instances ran simultaneously
Detected at 4:06 AM
