Claude Code v2.1.311 Update Fixes Several Freezes and Errors

At a glance

Version 2.1.311 of Claude Code (a terminal tool that developers use with AI) is out. This release focuses on fixing bugs rather than adding new features. Problems that caused freezes when handling long files, and changes that did not take effect right away when a task was stopped, have been resolved.

Key points

1. 1

   Freezing that happened when reading and editing long documents or files has been reduced.

2. 2

   When a conversation goes over the 1M token limit (the amount of text an AI can read at once), it now shortens the conversation so it can continue.

3. 3

   Errors in connecting to MCP servers (the channels AI uses to connect to external tools) and in displaying commands have been fixed.

4. 4

   Problems where messages were shown incorrectly in remote control and cloud sessions have also been resolved.

Why it matters

For developers who use Claude Code every day, there should be fewer interruptions from stopped tasks and tangled conversation history.
