A proxy that stripped one header was doubling Claude Code's API bill

Version 2.1.239 fixes streaming on Bedrock behind proxies that remove the response Content-Type header. Claude Code silently fell back to re-running every turn without streaming, and each turn was billed twice. The same release makes cost estimates show the 1.1× premium that data-residency workspaces pay.

Claude Code vs Cursor: same $20, different shape

Both start at $20 a month, both speak MCP, both run skills and hooks, both reach CI. The difference is not the feature list. It is whether the agent lives inside an editor you adopt or inside the terminal you already have.

Claude Code 2.1.238 stops memory growth in long sessions

The August 20 release fixes what got in the way during long stretches of work rather than adding features. Tool results returned by subagents are now freed as soon as they leave the recent-view window, so memory in long interactive sessions stops growing without a ceiling. The release also fixes custom output styles sliding back to the default tone mid-session, along with a run of stalls in Remote Control. A new keybindingFlavor setting restores Bash behavior, where Ctrl+W deletes back to the previous space, and claude mcp list no longer starts disabled servers just to check their status.

Claude Code sessions can now message each other

Two open sessions can talk: Claude finds the others with ListAgents and sends a message through SendMessage, either because you asked or on its own when a change in one session affects the work in another. Only text Claude writes crosses over — never conversation history, never files. Since version 2.1.232 you can also address a session directly by typing @ followed by its name. The feature runs on macOS and Linux and needs version 2.1.224 or later, and /list-agents shows what is available. It pays off most when you keep the frontend and backend of the same project in separate sessions.

Auto mode becomes the default permission mode

Since August 14, auto mode is the default permission mode for new sessions on the Pro, Max, and Team plans. Instead of interrupting at every action, a classifier in the background lets safe actions through and stops risky ones. If you set a default mode yourself, it stays in force until you accept a one-time offer to switch, and a mode an organization mandates does not change automatically. One detail matters for your quota: the classifier calls auto mode makes no longer count against usage limits.

Claude Code 2.1.235 to 2.1.237: Concise style, ANTHROPIC_DEFAULT_MODEL, and spell checking

Three releases in three days change several things about daily work. Version 2.1.237 introduces a built-in Concise output style, in which Claude leads with the result and skips the preamble and the recap, and fixes prompt caching for sessions that go through a proxy gateway or a custom base URL. Version 2.1.236 adds the ANTHROPIC_DEFAULT_MODEL environment variable, which sets the model new sessions start on, and a notify_when_idle option that asks another session to report when it frees up. Version 2.1.235 introduces optional spell checking through aspell, hunspell, or ispell, and reduces memory and processor use for sessions running in the cloud.
