You'll notice
When automatic history compaction runs out of room, it now keeps recent messages instead of summarizing everything
What
Claude Code periodically compacts (summarizes) old conversation history to save space. When its usual round-based compaction options are exhausted, instead of summarizing the entire conversation history as a last resort, it now splits off a trailing block of the most recent messages to keep as-is, and only summarizes what came before that.
Why
This keeps your most recent messages intact even in the last-resort compaction case, so recent context isn't lost to summarization along with everything else.
