The changelog adds a warning before login expiry so background sessions don't die mid-run, a grey pause badge in the footer to confirm you're in manual permission mode, additional working directories now surfaced through MCP roots/list with change notifications, and a fix for SessionStart hooks not streaming in headless sessions, which had been idle-reaping remote workers mid-hook. These follow v2.1.202's switch to manual as the default permission mode. If you run long background jobs, re-authenticate first and confirm the pause badge before you walk away.

It now dedupes local CLAUDE.md files against checked-in ones, proposes trimming content it can derive from the codebase, ranks unused skills, MCP servers, and plugins by context cost, and flags slow hooks. Background subagents run by default and, when launched from claude agen...
If you use plan mode as a read-only sandbox before you approve anything, stop and upgrade first. v2.1.212 patched a real safety hole: in plan mode, file-modifying Bash commands could execute without the permission gate you'd expect. Anything below 2.1.212 could mutate files mi...
This one rearranged my week. An essay published August 4 walks through Databricks' independent benchmark of coding harnesses against its own multi-million-line codebase. Pi, a harness with four built-in tools and a system prompt under 1,000 tokens, paired with Opus 4.8 at xhig...
The Linux x64 payload is compressed with zstd for both install and auto-update, the binary drops another 2MB by storing bundled skill and prompt text more compactly, code loads on demand rather than staying resident, and the runtime garbage-collects sooner as the heap grows in...
One Claude Code release fixed two independent permission-check bypasses on the same day. That's the story. Version 2.1.221, shipped August 4, patches a Bash tool bypass where zsh could execute hidden commands embedded inside [[ ]] regex conditionals. The approval prompt never...
Hook matchers are now exact-match instead of substring, so a matcher like code-reviewer silently stopped firing. Switch to regex like mcp__brave-search__.* to match a hyphenated MCP server's tools (Changelog). And the streaming idle watchdog now defaults on: no stream events f...
