CodeWhale v0.9.5 adds automatic model selection based on prompt complexity, choosing between faster and more capable tiers. Session history now supports branching, forking, and resuming conversations with /tree, /branch, /fork, and /resume commands. Scout and Reviewer agents can now inspect code, Git, and GitHub in a read-only sandbox while keeping private notes separate from the transcript. A unified Fleet roster displays active background work pinned above the composer.
