Claude Code now warns you before an old chat eats into your 5-hour limit
Claude Code now warns Pro and Max subscribers before they resume an old conversation that would use a noticeable share of their 5-hour usage limit. The warning arrived in version 2.1.304, according to Anthropic's Claude Code changelog.

The prompt gives two choices: resume anyway, or start a new conversation. In a fresh conversation, Claude can look up the old one if you mention it.
Anthropic does not say what counts as a noticeable share. There is no published threshold.
Version 2.1.304 also adds a guided setup for auto mode and safer deletes
The same release adds /auto-mode-setup, which reads your project and recent sessions to teach auto mode about your environment. It also works on Bedrock, Vertex and Foundry.
Deleting a mounted drive or a top-level folder such as /Volumes, /media or WSL's /mnt/c with rm -r now triggers a safety prompt. Until now, only paths like /Applications got one.

Developers behind a gateway should update to version 2.1.305 or later to fix requests
Version 2.1.304 broke every request on Vertex, Bedrock and other providers when an endpoint or gateway rejected tool search. Version 2.1.305 fixes it by retrying without tool search. Developers who hit the bug should update to 2.1.305 or later.
It is the second usage fix in a few days. The previous round stopped prompt suggestions from spending credits.
Version 2.1.305 changes how the sandbox and MCP allowlists behave for admins
A new opt-in setting, sandbox.allowNestedUserNamespaces, lets sandboxed commands on Linux create user namespaces. Anthropic says this is for tools such as Chromium and rootless podman, and warns that it lets those commands get around the sandbox's file protections. It is off unless you turn it on.
Admins should also check their MCP allowlists. allowedMcpServers no longer filters stdio servers in managed-mcp.json that use a ${VAR} only in their environment settings. A server your allowlist left out will now load after the upgrade. Anthropic says to add it to deniedMcpServers to keep it off.
Version 2.1.306, the latest release, fixes claude -p in cloud sessions reporting "Not logged in".
