Claude Code v2.1.238 20 Aug 2026

Reconnect no longer replays your last message as a new turn

You'll notice

Useful4 Signal2

Sessions

Reconnecting no longer replays your last message and produces a duplicate turn.

What

When a session reconnects and the server replays earlier messages, those echoed user messages are now dropped with a debug log instead of being fed back into the prompt, which used to produce a duplicate turn.

Details

Messages are identified as replays by a flag on the incoming message and logged with their uuid.

Evidence

[bridge:repl] Ignoring replay echo: uuid=

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
