1. Claude Code (Anthropic)

Latest version: v2.1.150 (May 23, 2026)

New Features & Capabilities

  • v2.1.150 — Internal infrastructure improvements (no user-facing changes)
  • v2.1.149 — A major feature and security update with many improvements:
- /usage now shows a per-category breakdown of limits usage — skills, subagents, plugins, and per-MCP-server cost - /diff detail view can now be scrolled with keyboard (arrows, j/k, PgUp/PgDn, Space, Home/End) - Markdown output now renders GFM task list checkboxes (- [ ] todo / - [x] done) instead of plain bullets - Enterprise: new allowAllClaudeAiMcps managed setting to load claude.ai cloud MCP connectors alongside managed-mcp.json

Security Fixes (v2.1.149)

  • PowerShell permission bypass patched: Built-in cd functions (cd.., cd\\, cd~, X:) changed working directory undetected, letting later commands read outside the workspace
  • Sandbox write allowlist fixed in git worktrees — now covers only the shared .git directory (with hooks/ and config denied) instead of the entire main repo root
  • PowerShell prefix/wildcard allow rules (e.g. dotnet.exe build *) now correctly pre-approve native executables and scripts
  • Permission-analysis gap fixed where the parser trusted stale variable-tracking values for / paths across environments

Bug Fixes & Improvements (v2.1.149)

  • Fixed Bash tool exhausting macOS system file/vnode table and crashing the host on large directory trees
  • Fixed managed-settings approval dialog leaving terminal frozen after accepting at startup
  • Fixed cd and remote session creation failing with "Could not capture uncommitted changes" when the working tree has no real changes
  • Fixed cd failing silently when the script path contains spaces
  • Fixed thinking spinner staying amber across tool calls and onto fresh thinking bursts
  • Fixed collapsed Bash output reporting wrong hidden-line count for outputs with many short lines
  • Fixed slash-command argument-hint clipping trailing typed characters when hint overflows input box
  • Fixed argument-hint and progressive suggestions not appearing after Tab-completing a skill whose frontmatter description differs from its directory basename
  • Fixed stale "Failed to install Anthropic marketplace" banner showing when marketplace is already installed
  • Fixed PR badge in footer not updating immediately after gh pr create and other PR-state-changing commands
