+The Title feature now correctly handles editor configurations where some or all roots use a custom `modelElement`. Roots that do not accept the `title` element are silently skipped at runtime, and the feature logs a single warning when no root supports the title structure.

+It is no longer possible for top-level items that shared the same indentation in the original document to end up visually misaligned in the editor when the list is interrupted by another list or by an empty paragraph. It should now also be possible to paste a nested list item directly after its parent without it being flattened to the top indentation level.

+Added a new shape for `config.root.element` (and `config.roots.<rootName>.element` in the multi-root editor) that lets integrators describe the editable root element without supplying an existing DOM node. The configuration now accepts a tag-name string (for example `'h1'`) or a `ViewRootElementDefinition` object that specifies a tag name, CSS classes, inline styles, and arbitrary attributes. The `name` property is optional and defaults to `'div'`, so integrators can keep the default element and only add classes or attributes. Inputs are normalized to a canonical form: class names provided as whitespace-separated strings are split into individual tokens, and `attributes.class` is lifted into the `classes` array. The `<textarea>` and `<input>` tag names are rejected because they cannot host a rich-text editable.

+The `MultiRootEditor#createEditable()` method now accepts an existing `HTMLElement` (or a `ViewRootElementDefinition`) so that dynamically added roots can be attached to a caller-owned DOM element instead of always rendering a fresh one. Element shape supplied at root configuration time is persisted on the model root and replicated through real-time collaboration.

+Inline images are no longer allowed in roots (or other limit elements) that do not accept block content, such as `$inlineRoot` and any plugin-registered custom inline-only root. The rule is structural rather than name-based, so it also applies to custom limit element types contributed by integrators. This is a temporary guard until image type conversion (block to inline and back) can react to the surrounding context.
