**BREAKING:**
If you have own, custom lexical features, there will be a bunch of breaking API changes for you. The saved JSON data is not affected.
- `floatingSelectToolbar` has been changed to `toolbarInline`
- `slashMenu.dynamicOptions `and `slashMenu.options` have been changed to `slashMenu.groups` and `slashMenu.dynamicGroups`
- `toolbarFixed.sections` is now `toolbarFixed.groups`
- Slash menu group `options` and toolbar group `entries` have both been renamed to `items`
- Toolbar group item `onClick` has been renamed to `onSelect` to match slash menu properties
- slashMenu item `onSelect` is no longer auto-wrapped inside an `editor.update`. If you perform editor updates in them, you have to wrap it inside an `editor.update` callback yourself. Within our own features this extra control has removed a good amount of unnecessary, nested `editor.update` calls, which is good
- Slash menu items are no longer initialized using the `new` keyword, as they are now types and no longer classes. You can convert them to an object and add the `key` property as an object property instead of an argument to the previous SlashMenuItem constructor
- CSS classnames for slash menu and toolbars, as well as their items, have changed
- `CheckListFeature` is now exported as and has been renamed to `ChecklistFeature`
