Unclear It is not clear which of your messages the new check skips.
What
Compaction is how Claude Code summarizes older parts of a long conversation to free up room. It picks a point to split the conversation and decides which of your messages to keep in full.
That choice now has an extra check. Some of your messages are skipped as split points, unless the message was handed off.
Why
This changes which parts of a conversation survive compaction.
