Setting CLAUDE_CODE_RESTRICT_PERSONAL_CONFIG now stops your own skills, agents and hooks from widening permissions. In that mode, errors in your user settings file block every prompt and tool call until you fix them. You can set transcriptCacheTtl to 5m to ask for 5-minute prompt caching instead of the default 1 hour. claude mcp serve has a new --session-tunnel mode that connects through a relay. Idle conversations are now compacted shortly before their prompt cache runs out. Plugins can now send notifications through your terminal.

Several features are in this build but not switched on yet. Print mode can show each turn's text result as soon as that turn ends. MCP servers that failed with a retryable error can be retried at the start of the next turn. Images can be re-encoded as smaller WebP files when that saves space. Work on cloud sessions continues, with remote tool requests now pausing while the host computer sleeps. The fleet view can group and pin cloud sessions.

Tool search no longer freezes Claude Code when you have very many tools. A queued message that gets dropped is now handed back to you instead of being discarded. Prompts typed during a left-arrow hand-off to background agents are no longer lost. If a model rejects the 1M-token context option, Claude Code now leaves it out instead of failing every request. Plugin sync from claude.ai no longer removes plugin files that another running session is using. The end-of-turn message no longer includes token budget figures.

Written by our agent from the shipped bundle, not by Anthropic.

Five to try today

Picked from 34 you can use now
  1. claude mcp serve gains an HTTP mode and --session-tunnel, limited to cloud-remote sessions

    In cloud-remote sessions only, claude mcp serve can run over HTTP, dial a session tunnel, read tokens from a descriptor and return tool output objects

    Extensions
  2. New CLAUDE_CODE_AUTOUPDATER_DISABLED_BY_HOST lets a host stop plugin auto-updates

    A host program can set CLAUDE_CODE_AUTOUPDATER_DISABLED_BY_HOST so plugin auto-updates stay off under the host's version pin

    Extensions
  3. Plugin UI gains ui.notify and Button text from children; search passes searchOtherAppsData

    Plugin UI adds a ui.notify operation and Button text from children, and the Grep search now passes a searchOtherAppsData flag

    Extensions
  4. A new setting limits what your own skills, agents and hooks can do

    Setting CLAUDE_CODE_RESTRICT_PERSONAL_CONFIG stops your own skills, agents and hooks from widening permissions, and makes key hooks required

    Settings & config
  5. New CLAUDE_CODE_RESTRICT_PERSONAL_CONFIG mode restricts your own Claude Code files

    Setting CLAUDE_CODE_RESTRICT_PERSONAL_CONFIG starts a session that restricts your own Claude Code files, alongside the other restricted modes

Anthropic’s official release notes

Published verbatim by Anthropic for v2.1.295. Text is unmodified from the upstream changelog. Everything else on this page came out of the bundle instead, which is why the two lists don't match.

Of these 143 bullets, 35 name something an entry on this page also names, 32 name something no entry here does, and 76 name nothing specific enough to line up either way. The pairings are made on names both sides wrote down, a flag or a setting or a slash command, so read one as probably the same thing rather than as a fact, and read the middle number as candidates rather than as a miss count.

A model matched these bullets to the GitHub issues they fix, so a link can be wrong.

System prompt

1 added and 1 removed, of 218 lines, about 22 words, in the prompt 14 of 27 arms receive. 4 other prompts also changed. The appended system-reminder blocks moved: 1 line added, 1 line removed.

Claude Code, interactive mode

13 prompt changes in this release could not be quoted from the build, so no entry on this page describes them.

Documentation

What the docs did around this release

568 documentation changes were recorded within 24 hours either side of this release, nearest first. The closest 12 are below. They're here because they happened near this release in time. That's not a claim that this release caused the edit, or that the page documents anything in it.
