2.1.30 — Claude code - Product release notes & changelog tool

Added pages parameter to the Read tool for PDFs, allowing specific page ranges to be read (e.g., pages: "1-5"). Large PDFs (>10 pages) now return a lightweight reference when @ mentioned instead of being inlined into context.
Added pre-configured OAuth client credentials for MCP servers that don’t support Dynamic Client Registration (e.g., Slack). Use --client-id and --client-secret with claude mcp add.
Added /debug for Claude to help troubleshoot the current session
Added support for additional git log and git show flags in read-only mode (e.g., --topo-order, --cherry-pick, --format, --raw)
Added token count, tool uses, and duration metrics to Task tool results
Added reduced motion mode to the config
Fixed phantom “(no content)” text blocks appearing in API conversation history, reducing token waste and potential model confusion
Fixed prompt cache not correctly invalidating when tool descriptions or input schemas changed, only when tool names changed
Fixed 400 errors that could occur after running /login when the conversation contained thinking blocks
Fixed a hang when resuming sessions with corrupted transcript files containing parentUuid cycles
Fixed rate limit message showing incorrect “/upgrade” suggestion for Max 20x users when extra-usage is unavailable
Fixed permission dialogs stealing focus while actively typing
Fixed subagents not being able to access SDK-provided MCP tools because they were not synced to the shared application state
Fixed a regression where Windows users with a .bashrc file could not run bash commands
Improved memory usage for --resume (68% reduction for users with many sessions) by replacing the session index with lightweight stat-based loading and progressive enrichment
Improved TaskStop tool to display the stopped command/task description in the result line instead of a generic “Task stopped” message
Changed /model to execute immediately instead of being queued
[VSCode] Added multiline input support to the “Other” text input in question dialogs (use Shift+Enter for new lines)
[VSCode] Fixed duplicate sessions appearing in the session list when starting a new conversation
