Two Claude Code releases in a day โ and one that finally lets /rewind cross a /clear.
A quiet day on the newsroom: no new product or research post landed June 24. Where yesterday actually moved for builders was the changelog โ Claude Code shipped 2.1.190 and 2.1.191 on the same day, and the later one adds a recovery feature people have wanted for a while, plus a ~37% cut to streaming CPU.
LEDETwo releases, one genuinely useful feature
Claude Codev2.1.191
Claude Code shipped both 2.1.190 and 2.1.191 on June 24, per the official changelog. 2.1.190 is a housekeeping point release โ its entry reads only "Bug fixes and reliability improvements" โ but 2.1.191 is the substantive one, and it leads with a rewind change that closes a long-standing gap.
Until now, running /clear was a one-way door: it reset the conversation and your
/rewind history went with it. 2.1.191 "Added /rewind support for resuming a
conversation from before /clear was run," so an accidental clear no longer strands the
work you were mid-way through. For anyone who runs long, multi-hour sessions and treats /clear as
a soft reset, this is the difference between a recoverable misclick and a lost thread.
The same release is unusually performance-heavy. It "Reduced CPU usage during streaming responses by
~37% by coalescing text updates to 100ms" and trimmed long-session memory growth from the terminal
output cache โ both of which matter most on the exact long-running, high-token sessions where Claude Code has
historically felt heaviest. What to watch: whether the 100ms coalescing interval is noticeable on very fast
terminals, and whether rewind-across-clear becomes the default mental model for session recovery the way
/rewind itself did.
BRIEFSThe rest of yesterday, ranked
2.1.191 makes stopping a background agent mean it. The release "Fixed background agents resurrecting after being stopped โ stopping an agent from the tasks panel is now permanent," ending a class of bug where a killed agent could come back. It also softens a daily friction point: the sandbox network permission dialog now means "hosts you allow with 'Yes' are remembered for the rest of the session instead of re-prompting on every connection," so an allowlisted host stays allowed without a prompt storm.
The same release hardens MCP against flaky networks in three places. Capability discovery โ
tools/list,
prompts/list, resources/list โ "now retries transient network errors with short
backoff." MCP OAuth "discovery and token requests now retry once after transient network errors, and headless
environments skip the browser popup and go straight to the paste-the-URL prompt." And error messaging
improves: "HTTP 404 errors now show the URL and point to your MCP config." Fewer flaky
failures, clearer diagnostics when a server is misconfigured.
Smaller 2.1.191 fixes worth knowing: scroll position no longer jumps to the bottom while you read earlier
output mid-stream; /voice now explains the restriction when an org policy disables it instead of
showing a generic "not available"; hooks with comma-separated matchers (e.g. "Bash,PowerShell")
that were "silently never firing" now fire; and a /permissions Recently-denied approval "now
persists on close instead of being silently discarded."
(full notes)
Whether the next 2.1.x cuts a feature release on top of the two June 24 point drops, and whether June 23's Claude Tag โ still the freshest thing on the newsroom โ picks up its promised expansion beyond Slack. The Claude Platform release-notes page was unreadable to the automated sweep (JS-rendered, no rendered fallback available), so any API-side change dated June 24 is unconfirmed here rather than ruled out.
/rewind-before-/clear addition, the ~37% streaming-CPU reduction via 100ms coalescing, reduced long-session memory growth, the permanent background-agent stop, the sandbox network-permission "remember allowed hosts" change, the MCP capability-discovery / OAuth / HTTP-404 reliability improvements, and the scroll, /voice, comma-matcher-hook, and /permissions fixes. The newsroom, engineering, and status pages were swept and carried no item dated June 24; the day's largest Anthropic-adjacent headline (the Alibaba filing) has no primary Anthropic source and is The Wire's beat, so it is excluded. Figures and version numbers are quoted, not recalled.
