ImprovementsSection of the release
When starting with --sdk-url and --resume, the CLI can now kick off an early hydrate-reads prefetch (startEarlyHydrateReads) concurrently with the rest of startup, to warm session/history state ahead of the SDK connection coming up. The result is threaded through as earlyHydrateReads in the prepared-session config.
The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.

Confirmed sinceAnthropic's documentation has since written up --resume, on Claude Code changelog.* Improved `--continue` / `--resume`: the conversation appears immediately instead of waiting for SessionStart hooks, and the first message no longer re-reads the whole transcriptchangelogsee the edit
