Windsurf's desktop changelog (now hosted on docs.devin.ai — Windsurf has become Devin Desktop) shows v3.9.19 (Sep 8) removing the legacy Cascade agent entirely: "Devin Local is the only agent available in Devin Desktop", with a 'Continue in Devin Local' migration path and a reorganized Local/Worktree/Cloud location picker. v3.10.23 (Sep 10) follows with SSH remote agent hosts and ACP permanently enabled, stripping the last legacy Cascade entry points (Vibe & Replace, Deploy, workflow commands).
Windsurf removes Cascade; Devin Local becomes its only agent

Imported from the existing research archive. Migration preserves the recorded judgment and is not a fresh verification.
What this means for you
A top-5 coding tool has now fully swapped its agent runtime post-acquisition — the fastest full-runtime replacement in this market so far. Teams still on Windsurf/Cascade workflows need to migrate or re-evaluate; for everyone else it is a live case study of how quickly agent-tool consolidation executes once an acquisition closes.
