### Breaking changes

`NodeType.isRepeated` is now called `isAnonymous`, which more accurately describes what it means.

`NodeGroup` has been renamed to `NodeSet` to avoid confusion with `NodeProp.group`.

The `applyChanges` method on trees is no longer supported (`TreeFragment` is now used to track reusable content).

Trees no longer have `cut` and `append` methods.

### New features

It is now possible to pass a node ID to `SyntaxNode.getChild`/`getChildren` and `NodeType.is`. Allow specifying a tree length in Tree.build

`Tree.build` now allows you to specify the length of the resulting tree.

`Tree.fullCursor()` can now be used to get a cursor that includes anonymous nodes, rather than skipping them.

Introduces `NodeType.define` to define node types.

The new `TreeFragment` type is used to manage reusable subtrees for incremental parsing.

`Tree.build` now accepts a `start` option indicating the start offset of the tree.

The `Input` type, which used to be `InputStream` in the lezer package, is now exported from this package.

This package now exports a `PartialParse` interface, which describes the interface used, for example, as return type from `Parser.startParse`.
