Tools & dev

  • claude-code v2.1.185 (June 20) improves stream-stall UX messaging; v2.1.183 (June 19) blocks destructive git ops (reset --hard, checkout --, clean -fd, stash drop, amend on other sessions’ commits) and infra-destroy commands unless you explicitly ask — good defensive default. GitHub releases
