# Change Log

## mobx-bonsai 2.3.0

- Data reconciliation optimizations (e.g. `applySnapshot`):
  - If a snapshot of a sub-object is passed to reconcile with such sub-object then reconciliation will be skipped for that sub-tree.
- If an object is not updated after a reconciliation then the snapshot will be kept stable.

## mobx-bonsai 2.2.2

- Fixed undo manager not working with certain decorator modes.

## mobx-bonsai 2.2.1 / mobx-bonsai-yjs 2.1.1

- Fixed Mobx 4/5 compatibility.

## mobx-bonsai 2.2.0

- `observer` is no longer used for nodes not under `onDeepChange` detection.
- Added `setGlobalConfig({ checkCircularReferences: boolean })` option to enable/disable circular reference detection when attaching nodes. When enabled (opt-in), throws an error if a node would become an ancestor of itself. Disabled by default for performance reasons.
- Optimized a bit snapshot invalidation.

## mobx-bonsai 2.1.1

- Fixed `onDeepInterceptedChange` so it supports returning the change to accept it or returning `null` to cancel it, like mobx `intercept` does.

## mobx-bonsai 2.1.0

- Reduced a bit memory usage per node.
- Added `onDeepInterceptedChange` to handle changes -before- they happen.
- Added `UndoManager`. (Note: If you are using the `Y.js` binding you should still use its own undo manager wherever possible).

## mobx-bonsai-yjs 2.1.0

- `yjsOrigin` parameter in `bindYjsToNode` now accepts either a `symbol` or a `() => symbol` function. When a function is provided, it will be called dynamically to retrieve the current origin symbol for each transaction, allowing for runtime origin symbol selection.

## mobx-bonsai 2.0.0

- Y.js bindings have been moved into a separate `mobx-bonsai-yjs` package. This solves issues when using the Y.js bindings on a ESM module environment.
- Errors thrown by Y.js bindings will be now of type `MobxBonsaiYjsError` instead of `MobxBonsaiError`.

## mobx-bonsai 1.1.2

- Fix so that reassigning a same value won't invalidate an snapshot.

## mobx-bonsai 1.1.1

- Make Yjs dependency truly optional.

## mobx-bonsai 1.1.0

- Added an `extends` method to node types so that they can extend other node types.
- `applyPlainObjectToYMap` / `applyPlainArrayToYArray` are no longer wrapped in mobx actions in case they want to track the original values.

## mobx-bonsai 1.0.0

- Initial public release.
