Claude Code Fixes Fork-Session Lineage Loss After Compaction and Preserves Permission Answers Across Background Subagents
Two 2.1.234 fixes land directly on the subagent-forking default that shipped in 2.1.232: fork-session lineage was being lost after compaction, and permission answers were not being preserved across background subagent tool prompts. Both were silent correctness bugs in long-running fan-out sessions — a forked subagent would lose its parentage mid-run, and you would get re-prompted for permissions you had already granted. If you turned forking on when it became the default, upgrading is worth it.
