The gist: Claude Code v2.1.149 introduces categorized usage reports, enhanced keyboard navigation, and ten security patches, particularly for PowerShell bypasses and sandbox access control.
The new version of Claude Code brings detailed breakdowns of resource utilization, improved keyboard navigation, and numerous security patches for PowerShell and the sandbox environment.
Claude Code v2.1.149 extends the developer platform with significant feature improvements and security adjustments. The new `/usage` function enables engineers to get a categorized breakdown of their resource utilization by skills, subagents, plugins, and MCP servers. At the same time, the `/diff` detail view has been enhanced with keyboard navigation using arrow keys, j/k navigation, and Page-Up/Down functions.
On the Markdown side, GitHub-Flavored-Markdown task lists are now correctly rendered with checkboxes (`- [ ] open` and `- [x] completed`) instead of bullet points. For enterprise environments, a new parameter `allowAllClaudeAiMcps` has been added, which can load Claude.ai Cloud MCP connections alongside managed MCP configurations.
The security adjustments address several critical gaps: a PowerShell bypass protection affects built-in `cd` functions that previously changed the working environment undetected. A sandbox error in Git worktrees was corrected that previously accessed the entire repository root directory. Additionally, PowerShell prefix and wildcard rule checks were repaired, as well as permission analysis for directory change commands optimized. A macOS-specific crash caused by exhausted file descriptors on the `find` command was also fixed.
