Summary

Rebuild version history around a single selected version and a consistent read-only preview lifecycle. Opening the sidebar selects the current version; users can name, filter, compare, restore, and delete versions, and applications can replace snapshot menu items while reusing the built-in actions.

Rationale

Version history needs predictable selection, loading, and closing behavior across storage backends. Menu customization should preserve restore, preview, and async follow-up behavior without requiring applications to duplicate sidebar internals.

Changes

  • Add composable read-only restrictions and prevent link editing while the editor is locked.
  • Unify versioning list, view, and loading state; handle overlapping requests, restores, closing, and scrolling to the first change. Update the in-memory, Yjs 13/14, and YHub adapters.
  • Rebuild the sidebar with inline naming, named-version filtering, comparison controls, keyboard navigation, loading/error feedback, and updated translations and UI adapters.
  • Expose composable snapshot menus, a default-items fragment, and action hooks colocated with their components. Support explicit menu hiding, presentation overrides, merged classes, and disabled items across Mantine, Ariakit, and Shadcn.
  • Refresh attribution colors, deleted-block presentation, example histories, and the suggestion gallery's responsive and dark-mode styling. Fix nested bullet markers and guides using CSS inheritance, and remove issue notes for accepted single-user nesting behavior.
  • Expand versioning, adapter, read-only, and sidebar regression coverage.

Impact

This includes breaking changes to the versioning state/adapter contracts and sidebar customization API. Consumers using the previous store fields, capability flags, or sidebar configuration must migrate; the updated examples demonstrate the new contracts. Attribution colors and deleted-block rendering also change.

Testing

  • Focused core suites: 240 tests passed across 11 files, covering versioning, adapters, YHub, read-only restrictions, attribution colors, and diff scrolling.
  • React sidebar and read-only link toolbar suites: 71 tests passed across 2 files.
  • Commit hooks passed vp check --fix.
  • Manually checked the two- and three-level nested bullet examples in Suggestions and Versioning modes in the running gallery, including markers, 24px indentation, and guide lines.
  • Manually verified that the six supported single-user nesting examples no longer show issue badges or panels.

Screenshots/Video

The updated versioning demos and suggestion gallery provide interactive before/after views for review. Manual visual checks used the running gallery.

Checklist

  • Code follows the project's coding standards.
  • Unit tests covering the new feature have been added.
  • All existing tests pass.
  • The documentation has been updated to reflect the new feature.

Additional Notes

The full browser suite was not rerun. Earlier deleted-block baseline updates are included, but the latest nesting, table-deletion, and dark-mode changes were checked manually; affected browser screenshots and exporter/static visual baselines have not been regenerated for those changes.

Summary by CodeRabbit

Versioning platform

Layer / File(s) Summary
Core versioning contracts and orchestration
packages/core/src/extensions/Versioning/*, packages/core/src/extensions/ReadOnly/*, packages/core/src/y/versioning/*
Versioning now uses structured list and view state, asynchronous preview coordination, synchronized read-only state, YHub activity timestamps, rollback metadata, and first-change scrolling.
Versioning sidebar and menus
packages/react/src/components/Versioning/*, packages/react/src/versioning.ts, packages/ariakit/src/versioning/*, packages/mantine/src/versioning/*, packages/shadcn/src/versioning/*
The sidebar now supports filtering, comparison, inline naming, keyboard navigation, loading and error states, reusable menu actions, accessibility properties, and a public @blocknote/react/versioning entry point.
Examples and collaboration integration
examples/07-collaboration/*, examples/08-extensions/02-versioning/*, playground/src/examples.gen.tsx
Examples now seed version history, use revised Yjs and YHub APIs, persist or replay sample data, and document read-only preview behavior.
Attribution, styling, localization, and validation
packages/core/src/y/extensions/*, packages/core/src/user/*, packages/core/src/i18n/locales/*, packages/react/src/editor/styles.css, tests/*, pnpm-workspace.yaml
Attribute changes, user colors, editor styling, locale strings, dependency versions, fixtures, and unit/end-to-end coverage were updated for the new contracts.

57-57: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Restore is now silently unavailable for the v13 adapter.

The adapter no longer provides applyRestore. VersioningExtension gates restore on endpoints.restore && applyRestore, so restore resolves to undefined even when the backend defines restore. Consumers of the v13 adapter that previously called restore (and caught the "not implemented" error) now find the method missing.

Document this removal in the changelog or migration notes for the versioning contracts.

Based on learnings that breaking public API changes must be clearly documented with a migration path for consumers.

Inline comments:
In `@examples/07-collaboration/12-multi-doc-versioning/src/App.tsx`:
- Around line 88-92: Update seedSampleDocument and the surrounding index.create
flow so seeding remains retryable until every PATCH succeeds, rather than
treating the locally created index entry as completion. When retrying after
partial success or after index.remove, reconcile or reset the partially seeded
remote document before applying the remaining seed operations, while setting
SEEDED_KEY only after full success.

In `@examples/07-collaboration/12-multi-doc-versioning/src/DocumentEditor.tsx`:
- Line 169: Update the onSync handler in DocumentEditor so it sets synced only
when isSynced is true, preserving the latched successful-synchronization state
when the provider later emits sync(false) during a disconnect.

In `@packages/core/src/editor/Block.css`:
- Line 1213: Regenerate the exporter visual baselines affected by the Block.css
changes, then compare the generated results against the editor ground truth and
update only the corresponding baseline artifacts.

In `@packages/react/src/components/Versioning/usePreviewRow.ts`:
- Around line 57-59: Update the non-current branch of compareToId in
usePreviewRow so a missing row (findIndex returning -1) produces no baseline
instead of selecting snapshots[0]; retain the existing next-snapshot selection
when the row is present.

In `@packages/react/src/components/Versioning/VersioningSidebar.tsx`:
- Line 19: Document the breaking Versioning API changes: in
packages/react/src/components/Versioning/VersioningSidebar.tsx:19 explain
migrating from filter="named" to defaultNamedOnly={true}, and in
packages/react/src/editor/ComponentsContext.tsx:271-274 document that custom
ComponentsContext maps must provide Versioning.Loader. Release the package using
the major option in vp run deploy, since the publish workflow uses the release
tag version.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Retry failed sample seeding.

index.create writes the local index before seedSampleDocument finishes. If a later PATCH fails, the catch block keeps the entry, and index.docs.length > 0 prevents another seed attempt. SEEDED_KEY is set only after success.

The user can delete the entry with index.remove and revisit. This restores the seeding path because the key remains unset. However, index.remove only clears local data. Earlier successful PATCH requests can leave a partially seeded remote document.

Persist retry state until all PATCH requests succeed. If you remove the index entry, also handle the partially seeded remote document.

Allow navigation after sample seeding fails.

If sample seeding fails, seedStatus remains "failed". Document navigation sets docId through the hash route, but no route or state update resets seedStatus. The failed-state branch renders before activeDoc, so it continues to hide DocumentEditor. Retry also cannot restart seeding because the effect returns when docId is set.

Ignore or reset the failed seed state when docId is set.

some sanity-check questions on how editable relates to readonly:

  • the event (notify) doesn't trigger when ReadOnly changes right? should it?
  • Can't / should we use our new ReadOnly system instead of calling _tiptapEditor.setEditable directly in isEditable = false?

Is toggling classnames on bn-block-content safe or could it conflict with Prosemirror (and it's MutationObserver)?

I haven't reviewed this file in depth (line-by-line), but couple of questions come up:

  • This file is both a YHub API Client and an implementation of our VersioningEndpoints interface, right? Can we extract a YHub API REST client that's as "pure" as possible? (no blocknote logic around it, just fetch REST calls and parameter conversions)
  • The version names are now stored in a Y.Array which I don't think should / will be the expected way to do this. Can you coordinate this with Kevin? Versioning API YHub Product#90
  • Is there any other "magic" we're doing in this file that we should validate with Kevin or you think should have an easier solution (on YHub's side)?

There isn't a versioning API in yhub yet, I'm not sure what Kevin is thinking on doing here, but until then, it needs to be stored somewhere, so on the Y.Array it will be

Not really any magic here, nothing that I'd upstream to Kevin.

Keep feature-owned read-only restrictions separate from the application editable setting. Notify transaction subscribers without document-change events and prevent link editing while locked.
Use consistent author colors and derived light tints for marks and tooltips. Compact deleted-block cards and update the corresponding visual baselines.
Model loaded history and preview state explicitly, centralize preview loading and supersession, and derive mutation capabilities from available methods. Update in-memory, Yjs, and YHub adapters with restore handling and focused tests.
Use a single selected version with inline naming, named-version filtering, comparison controls, and composable menus. Centralize action supersession and closing, and update UI skins, translations, and regression tests.
Seed useful version histories, adapt demos to the new sidebar and versioning API, and update documentation, dependencies, and generated example metadata. Preserve the existing worktree setup configuration.

Return to Current when the backend removes the snapshot.

For a deletion backend, remove() can remove the row from list.snapshots. In that case, hidden is false, even when view still uses the deleted snapshot or comparison baseline. The sidebar then keeps a view that has no corresponding row.

Test whether the snapshot remains visible after removal. Return to Current when it does not.

🟡 Minor · Prevent an older list response from overwriting a rename.

packages/core/src/extensions/Versioning/Versioning.ts:313
🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Prevent an older list response from overwriting a rename.

rename patches the store without superseding listing. If an earlier list response arrives after this patch, refreshList replaces the list with the old name. The sidebar then shows stale data until another refresh.

Use the generation-aware refresh after the backend rename, or serialize this patch after the active listing completes.

Proposed fix
             const snapshot = requireSnapshot(id);
             await endpoints.rename!(snapshot, name);
-            store.setState((state) => {
-              if (!state.list.loaded) {
-                return state;
-              }
-              const patch = (s: VersionSnapshot) =>
-                s.id === snapshot.id ? { ...s, name } : s;
-              return {
-                ...state,
-                list: {
-                  loaded: true,
-                  current: patch(state.list.current),
-                  snapshots: state.list.snapshots.map(patch),
-                },
-              };
-            });
+            await refreshList();

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Reject an unknown comparison snapshot.

Both preview entry points use getSnapshot for compareTo. If the identifier is stale or invalid, the lookup returns undefined and the requested comparison silently becomes a normal preview. This can show misleading version results.

Use requireSnapshot when compareTo is supplied.

Proposed fix
-      const compareToSnapshot = getSnapshot(previewOptions?.compareTo);
+      const compareToSnapshot =
+        previewOptions?.compareTo === undefined
+          ? undefined
+          : requireSnapshot(previewOptions.compareTo);

Apply the same change in previewCurrentVersion.

I'm not really following here. can there be multiple activity items with the same id?

// Stored labels can have newer timestamps, but only activity defines current.
const newestActivityTo = Math.max(...rows.keys());

for (const [id, entry] of versions.readEntries()) {

Isn't there an easier way to do a rollback? This whole collectFragmentIds seems, uhm, cumbersome to say the least?

Problem is that with the way that version snapshots are stored in the document, we can't just rollback to a timestamp since we will rollback the versions too.

This is one more argument for having Kevin expose a versioning API.

we still call store.setState manually a bunch of times in this file. Shouldn't we wire all calls through this method?

nitpick, but this is pretty intense (generation, listing, signal etc). Isn't there an easy util for this?

nice-to-have; this seems like status is a derived value of two stores. we can't set it up like that (derived / functional) instead of calling a method (syncStatus) to keep a property in-sync?

would this be a bug? (if the renderedView !== "live", but we call exitPreview?). Or could it happen when loading still loading for example (like above)? Zoomed out, mostly wondering if we can simplify the state management (quite some wiring between view states / loading / errors, etc)
