(0.144.0) — [release notes](https://github.com/ianstormtaylor/slate/releases/tag/slate%400.144.0) - Deleting beside two non-selectable blocks, or a read-only block whose content is all non-selectable, now removes them instead of merging their text. (0.144.0) — [release notes](https://github.com/ianstormtaylor/slate/releases/tag/slate%400.144.0) ### New APIs and options - Applies an outside document through Slate operations, keeping unchanged nodes and preserving selection, refs and history. (0.144.0) — [release notes](https://github.com/ianstormtaylor/slate/releases/tag/slate%400.144.0) ### Behavior and default changes - With history enabled, each setChildren call is recorded as one undo step, separate from typing before and after it. (0.144.0) — [release notes](https://github.com/ianstormtaylor/slate/releases/tag/slate%400.144.0) ### Fixes and other changes - No longer returns points inside consecutive non-selectable elements or inside a non-selectable first child of a void or read-only element. (0.144.0) — [release notes](https://github.com/ianstormtaylor/slate/releases/tag/slate%400.144.0) - No longer returns points inside consecutive non-selectable elements or inside a non-selectable first child of a void or read-only element. (0.144.0) — [release notes](https://github.com/ianstormtaylor/slate/releases/tag/slate%400.144.0) ## slate 0.143 ### New APIs and options - Adds editor.getSplitProperties(node, path) to choose properties copied to the new right-hand node by Transforms.splitNodes; createEditor supplies it, while structural editor implementations and mocks must add the method. (0.143.0) — [release notes](https://github.com/ianstormtaylor/slate/releases/tag/slate%400.143.0) ## slate 0.142 ### New APIs and options - createEditor accepts an optional type parameter; createEditor() returns a plain BaseEditor, so plugin chains are type-checked against the plugins actually applied. (0.142.0) — [release notes](https://github.com/ianstormtaylor/slate/releases/tag/slate%400.142.0) ### Fixes and other changes - Opt-in edge affinity leaves collapsed selections outside text nodes to the transform, avoiding a “Cannot get the leaf node” error. (0.142.1) — [release notes](https://github.com/ianstormtaylor/slate/releases/tag/slate%400.142.1) ## slate 0.141 ### Breaking changes - Dropping a dragged block void onto the middle of a paragraph now splits the paragraph in the same way as pasting a block-level node. (0.141.0) — [release notes](https://github.com/ianstormtaylor/slate/releases/tag/slate%400.141.0) - Pasting block-level nodes mid-block now splits the block so the nodes land between its halves, and moves the cursor to the start of the second half. (0.141.0) — [release notes](https://github.com/ianstormtaylor/slate/releases/tag/slate%400.141.0) ### New APIs and options - Adds a query for consistent insertion at inline and mark boundaries; BaseEditor requires it, while createEditor supplies it automatically. (0.141.0) — [release notes](https://github.com/ianstormtaylor/slate/releases/tag/slate%400.141.0) - Adds an opt-in editor hook that configures insertion affinity at inline boundaries; it defaults to null, preserving existing behavior. (0.141.0) — [release notes](https://github.com/ianstormtaylor/slate/releases/tag/slate%400.141.0) - Adds a filter option called for each fragment node with the destination block entry; returning false skips that node.

(0.138.0) — [release notes](https://github.com/ianstormtaylor/slate/releases/tag/slate%400.138.0) - Supports select; explicit true moves the caret to the result, while moving retains its existing selection-following behavior by default. (0.138.0) — [release notes](https://github.com/ianstormtaylor/slate/releases/tag/slate%400.138.0) - Supports select; explicit true moves the caret to the result, while moving retains its existing selection-following behavior by default. (0.138.0) — [release notes](https://github.com/ianstormtaylor/slate/releases/tag/slate%400.138.0) - Supports select; explicit true moves the caret to the result even with an explicit at, and splitting selects by default when at is omitted.
