Claude Code shipped two release trains worth grabbing: shell-aware mode, `/rewind` past `/clear`, and fixed hook matchers.

Story

Week 26 (June 22 to 26, v2.1.185 to 192) added claude mcp login for shell-based MCP auth, /rewind support to resume from before a /clear, shell mode that reacts to command output, and background subagents that now surface permission prompts instead of silently auto-denying (Releasebot). The June 27 release added fullscreen mouse controls and, importantly, fixed hook matchers with hyphenated identifiers like code-reviewer and mcp__brave-search that were accidentally substring-matching. They now exact-match (Releasebot). If your hooks were firing on the wrong tools and you couldn't figure out why, that's the bug. Background agents also stopped telling the model to "end your response," so the parent keeps working while a subagent runs.
