Release v6.0.0 · SSShooter/mind-elixir-core

6.0.0 - 2026-11-02

See skills/migrate-to-v6/SKILL.md for the full migration guide.

Pass rtl: true to Options to switch node topics, the editor, labels and context menu to right-to-left text direction (Arabic, Hebrew, Persian, Urdu); branch layout axis is unaffected.
Add ar (Arabic) locale to the i18n export.
Pass a markdown renderer to Options (and new Outliner(…)) to render topics as Markdown / KaTeX in both the map and the outliner.
Arrow-key navigation crosses into neighbouring branches at boundaries: ArrowDown from the last child and ArrowUp from the first child of a branch step into the nearest sibling branch, landing at its first/last child or the branch node itself when collapsed.
mei.diffRefresh(data) applies only the difference between the current document and data, keeping unchanged nodes' elements, listeners and focus state; falls back to refresh when the change cannot be expressed incrementally.
Collapse / expand is now undoable: Ctrl+Z restores the previous fold state, and folds from the outliner and the map share one undo timeline.
expandNode and expandNodeAll accept { silent: true } to skip the history entry, so an auto-expand before adding a child costs no extra undo step.
The outliner ships as its own entry point: import { Outliner } from 'mind-elixir/outliner' and import 'mind-elixir/outliner/style.css'; the main entry still re-exports it unchanged.

Input box now preserves line breaks (white-space: pre-wrap) so Shift+Enter newlines survive editing in WebKit.
init() no longer throws a TypeError when the instance is destroyed during document.fonts.ready (React StrictMode fast mount/unmount).
destroy() now properly releases internal references (focus backup tree, undo stack, pan/arrow helpers, dragged-node list) to prevent memory leaks.
Ensure focus backup tree and undo baseline are properly reset/re-anchored when using refresh(data) or undoing inside focus mode.
Folding a childless node or re-applying the existing fold state no longer touches the DOM or the history stack.
reshapeNode no longer passes an origin that already equals the new state to the operation event.
Removing a node whose parent pointer and sibling array had drifted apart no longer deletes the last sibling (splice(-1, 1)).
removeListener now drops every registration of a handler, not just the first.
createSummary with an unusable selection (nothing selected, the root, or nodes from different main topics) is now a no-op instead of throwing.

Undoing a no-op operation renders nothing; the incremental path only redraws when it patched something.
focusNode and cancelFocus clear the undo/redo stack, making the focus boundary a history boundary in both directions.
refresh(data) now leaves focus mode and fires a refresh event once the data is in place.
Plaintext export now escapes \ and line breaks (\\ / \n) so topics with Shift+Enter newlines round-trip correctly.

Undo/redo patches the map with diffRefresh instead of rebuilding it; at 5 461 nodes undoing a one-node change drops from ~73 ms to ~14 ms.
The structural diff reconciles children order per parent rather than per rendered container, fixing SIDE-layout convergence.
Outliner rendering is a keyed reconciliation: unchanged nodes keep their DOM element, listeners and focus state; re-rendering at 5 461 nodes drops from 94 ms to ~1 ms.
Outliner event listeners are delegated to the container (8 per-node listeners → 0), and opening the … menu no longer re-runs markdown/KaTeX over every topic.
The outliner is now a pure view of a MindElixir instance: standalone mode, refresh(), updateItem(), OutlineItem/OutlineData/OutlinerMei types, and the internal tree DSL (cloneTree, locate, walk, six mutating operations) are all removed.
Link rendering batches all geometry reads before any DOM writes, cutting forced reflows from one per node to one total; linkDiv at 5 461 nodes drops from 124 ms to 9.6 ms.
Moving several nodes no longer re-walks the whole tree once per node.
