Summary

The provided content details a series of updates and bug fixes across several versions of a Claude Code client, specifically versions 2.1.105 through 2.1.114. Key enhancements include the introduction of Claude Opus 4.7 with `xhigh` effort levels and auto mode for Max subscribers, alongside an interactive `/effort` slider. New features like `/ultrareview` for parallelized multi-agent code review and `/less-permission-prompts` for generating Bash/MCP allowlists were added. Security improvements focused on hardening `Bash(rm:*)` and `Bash(find:*)` rules on macOS and enhancing deny rule matching. Numerous fixes address issues such as crashes in permission dialogs, CLI behavior with native Claude Code binaries, `sandbox.network.deniedDomains` settings, fullscreen mode scrolling, `Ctrl+A`/`Ctrl+E` behavior, clickable long URLs, `/loop` and `/ultrareview` improvements, subagent stalling, and various UI and backend stability issues across Windows, macOS, and Remote Control clients.
