### Bug fixes

The [`setBlockType` command](https://prosemirror.net/docs/ref/#commands.setBlockType) command is now considered applicable when _any_ of the selected textblocks can be changed (it used to only look at the first one).

Fix crash when calling [`splitBlock`](https://prosemirror.net/docs/ref/#commands.splitBlock) when the selection isn't in a block node (by disabling the command in that case).

Fixes an issue where [`joinForward`](https://prosemirror.net/docs/ref/#commands.joinForward) might create a selection pointing into the old document.
