 # Changelog — session-flow plugin
 
+## 0.10.2 — 2026-07-19
+
+Fixed:
+
+- retro: the Phase 1.1 multi-session snippet now derives `HANDOFF_DIR` from the
+  resolved `memory_dir` (reads the `.claude/topic-docs.yaml` concern file, falls
+  back to `.work`) instead of hard-coding the bare default `.work/handoffs`. A
+  copy-as-is run of the snippet previously bypassed the memory_dir seam, missing
+  the handoff chain in any repo that relocates its memory tier.
+
