DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.225

Streaming read index no longer skips messages

Messages sent after a conversation reset or a cancelled request are no longer silently dropped.

What

Two index bugs in the input-stream loop are fixed, so messages after a reset or a cancelled request are not silently dropped.

Details
  • The read index is reset whenever a conversation_reset event appears in the pending batch, instead of only when a filtered condition held.
  • When a cancelled request's placeholder text message is spliced out, the read index is decremented if it sat past the removal point.
Evidence

conversation_reset

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