Bit Files

New Features

• pnpm v12 — Bit's package manager internals are migrated to pnpm v12, now running through the @pnpm/napi Rust engine, which also renders install output, answers bit why and owns the lockfile (#10508, [#10653])
• Opt-in support for pnpm's global virtual store (#10582)
• bit install --restore rebuilds the lockfile from the components' dependency graphs (#10325)
• A repeat install that is already up to date is skipped by the engine (#10720)
• bit ci sync — bi-directional sync between Bit lanes and git branches/PRs (#10541)
• Sync cross-scope lanes by mirroring the workspace-scope slice (#10644)
• PR run summary, with convergence decided from a status probe (#10581)
• Support GitHub Enterprise Server via GITHUB_API_URL and GITHUB_SERVER_URL (#10817)
• bit ci sync --init writes the sync rules for agents into AGENTS.md (#10835)
• Redesigned changes & compare experience — single-component compare, lane compare and the workspace/lane overviews share one bulk-fetched implementation, the Monaco code diff is replaced with a lean Shiki-based viewer, and the semantic API diff is a first-class view (#10378, [#10708], [#10716], [#10825])
• Workspace-root component — a component can live at the workspace root (rootDir: "."), with a new trackAllFiles flag (#10698)
• bit gc removes unneeded objects from the local scope (#10714)
• bit ripple simulate and bit lane updates commands (#10712)
• Hidden peer dependencies (#10066)
• Introduce the empty-env core aspect (#10535)

Improvements

• Warn when a new component id already exists on the remote (#10503)
• Add --delete to bit resume-export to clear stuck exports (#10683)
• bit delete --hard requires an interactive human confirmation (#10648)
• Deprecate bit validate --all in favor of --unmodified (#10560)
• bit diff --parent defaults to the current version and skips non-meaningful ancestors (#10526)
• Save the planned build tasks of a version tagged or snapped without a build (#10822)
• Show dependencies whose version is pinned by config (#10792)
• Explain why a text file shows as a binary conflict during merge (#10754)
• Profile timing for install phases (#10685)
• Report components that were not compiled for lack of a compiler (#10592)
• Rename bit ripple errors --log to --full-log, and show the real error in its summary (#10827, [#10509])
• Stabilize the node and edge order of bit graph --json (#10811)
• Expand the generated agent instructions (#10693)
• Extract md/mdx import detection into a detective component (#10519)
• Replace the community Slack links with Discord (#10699)

Performance

• Bundle both UI roots in one compilation and shrink the UI pre-bundle from 58MB to 16MB (#10628, [#10629], [#10637])
• Enable Node's built-in compile cache on startup, and stop loading hard-link-directory on every invocation (#10669, [#10599])
• Drop the lsof port pre-flight from server-routed commands (#10673)
• Reduce memory usage during snap on large workspaces (#10862)
• Bound the objects cache by bytes instead of count, and read flattened dependencies lazily from a separate object (#10723, [#10758])
• Speed up export of components with many objects (#10745)
• Faster version lookups: index version lookups in history walks and export, index version parents by hash, look up a single tag without copying all versions, speed up the ref-to-tag lookup, and use a set in VersionHistory.merge (#10869, [#10865], [#10739], [#10753], [#10868])
• Filter objects by type from their header when listing the repository (#10730)
• Copy small Source contents out of the shared inflate buffer (#10785)
• Skip needless deep copies when hashing and converting versions (#10741)
• Look up .bitmap components by name instead of scanning all of them (#10742)
• Reuse evicted components that are still in use (#10736)
• Batch, dedupe and bound dependency imports when building graphs from the filesystem (#10635)
• Let pnpm reuse the lockfile across installs, install without a readPackage hook, and filter the lockfile in memory when calculating the dependency graph (#10748, [#10787], [#10854])
• Avoid loading removed components and their envs on bit remove (#10836)

Bug Fixes

• Fix an issue where referenced non-head dependency snaps were not shipped when merging a lane to main and exporting (#10523)

• Retry transient remote-fetch failures (#10603)
• Fix an issue where newly exported components were missing the scope in .bitmap (#10538)

• Fix an issue where --tasks was ignored by the tag pipeline and full task-ids were not accepted (#10809)
