March 2026 performance summary for gitbutler: Delivered a broad set of SDK, type-gen, and graph work enabling deeper integration and more deterministic outputs. Key features delivered include expansion of the But SDK Core and API surface with new core functions (assignHunk, changesInWorktree, commitDetailsWithLineStats, branchDiff), plus treeChangeDiffs and improved type collection; APIs now provide full replacedCommit mappings. Implemented Commit history tracking with an untracked-picks workflow, introducing commit_mappings and a new Step::new_untracked_commit to improve frontend mappings. Strengthened type generation and runtime typings: async N-API wrappers (spawn_blocking) for frontend responsiveness, macro-enabled type casts and napi annotations, stable but-ts output, and improved handling of tuple types and diff typings. Refined branch creation algorithm to better reflect the graph and inter-reference relationships. Enabled deterministic schema generation by preserving order in schemars. Notable fixes include restoring correct usage of SDK types (UIMoveCommitResult) and suppressing unused import warnings. Added sampling rate support for high-frequency PostHog telemetry to balance data volume. Structural and architectural improvements: relocate RelativeTo into the but_rebase crate, rebase engine owning workspace/metadata, graph overlay enhancements for dropped references and multi-reference handling, and initial test scaffolding with clearer guidelines.
