February 2025 performance highlights for gitbutler: Delivered a major overhaul of the branch/BR workflow, improving per-branch publish controls and UI, removing the legacy BR publish button, and streamlining branch-related conditions to reduce user confusion and mistakes. Strengthened the push-to-review workflow with explicit topBranch handling and ensured that pushing updates consistently refreshes published stacks. Expanded Forge and PR review integrations to enable richer review experiences: a dedicated review card, PR link handling, Forge link display, Forge property support, user-friendly identifiers, and BR/PR synchronization. Additionally, improved reliability, observability, and developer experience: fixed off-by-one line numbering and kept line counters accurate post-push; ensured OG title metadata is produced correctly by awaiting server responses; introduced a Vitest testing setup for web app reliability; integrated PostHog metrics to monitor features and usage. Implemented two feature flags to guide users away from incomplete features and introduced chat-triggered patch reload with relaxed chat token requirements to enable smoother interactions.
