`editor.registerBatchCompleteHandler` has been replaced with `editor.registerOperationCompleteHandler`
#### Move arrow helpers from editor to tldraw ([#3721](https://github.com/tldraw/tldraw/pull/3721))
#### Breaking changes
-`editor.getArrowInfo(shape)` has been replaced with `getArrowInfo(editor, shape)`
-`editor.getArrowsBoundTo(shape)` has been removed. Instead, use `editor.getBindingsToShape(shape, 'arrow')` and follow the `fromId` of each binding to the corresponding arrow shape
- These types have moved from `@tldraw/editor` to `tldraw`:
- The `start` and `end` properties on `TLArrowShape` no longer have `type: point | binding`. Instead, they're always a point, which may be out of date if a binding exists. To check for & retrieve arrow bindings, use `getArrowBindings(editor, shape)` instead.
-`getArrowTerminalsInArrowSpace` must be passed a `TLArrowBindings` as a third argument: `getArrowTerminalsInArrowSpace(editor, shape, getArrowBindings(editor, shape))`
- The following types have been renamed:
-`ShapeProps` -> `RecordProps`
-`ShapePropsType` -> `RecordPropsType`
-`TLShapePropsMigrations` -> `TLPropsMigrations`
-`SchemaShapeInfo` -> `SchemaPropsInfo`

#### New migrations again ([#3220](https://github.com/tldraw/tldraw/pull/3220))
#### BREAKING CHANGES
- The `Migrations` type is now called `LegacyMigrations`.
- The serialized schema format (e.g. returned by `StoreSchema.serialize()` and `Store.getSnapshot()`) has changed. You don't need to do anything about it unless you were reading data directly from the schema for some reason. In which case it'd be best to avoid that in the future! We have no plans to change the schema format again (this time was traumatic enough) but you never know.
-`compareRecordVersions` and the `RecordVersion` type have both disappeared. There is no replacement. These were public by mistake anyway, so hopefully nobody had been using it.
-`compareSchemas` is gone. Comparing the schemas directly is no longer really possible since we introduced some fuzziness. The best thing to do now to check compatibility is to call `schema.getMigraitonsSince(prevSchema)` and it will return an error if the schemas are not compatible, an empty array if there are no migrations to apply since the prev schema, and a nonempty array otherwise.
Generally speaking, the best way to check schema compatibility now is to call `store.schema.getMigrationsSince(persistedSchema)`. This will throw an error if there is no upgrade path from the `persistedSchema` to the current version.
-`defineMigrations` has been deprecated and will be removed in a future release. For upgrade instructions see https://tldraw.dev/docs/persistence#Updating-legacy-shape-migrations-defineMigrations
-`migrate` has been removed. Nobody should have been using this but if you were you'll need to find an alternative. For migrating tldraw data, you should stick to using `schema.migrateStoreSnapshot` and, if you are building a nuanced sync engine that supports some amount of backwards compatibility, also feel free to use `schema.migratePersistedRecord`.
- the `Migration` type has changed. If you need the old one for some reason it has been renamed to `LegacyMigration`. It will be removed in a future release.
- the `Migrations` type has been renamed to `LegacyMigrations` and will be removed in a future release.
- the `SerializedSchema` type has been augmented. If you need the old version specifically you can use `SerializedSchemaV1`
