This version adds undo functionality to the keyboard engine, which makes it possible to undo text insertions, deletions, and autocompletions in chunks. This is currently opt-in. Enable the undoManager experiment to try it out.

This version also adds many more pickers and settings for various keyboard models, including a brand new KeyboardActionPicker. This will let us harmonize the settings tools, and avoid having to write separate code for each model.

This version also flattens the remaining namespaces, to complete the extensive namespace transition earlier than initially planned, to give us all time to migrate before KeyboardKit 11.

This also version starts reducing namespace nesting, as described in issue 1045. Expect less nesting and more surface-level types, with renaming guides to help you migrate.

This version updates some license information.

This version adds support for on-device next word prediction, using Apple's Foundation Models. This is available on iPhone 15 Pro and later, iOS 26.1 and later. Note that this is a very(!) new technology that is slower and less accurate than other autocomplete features. You can help improving it by providing feedback.

This version also tweaks the license validation to be much faster than before, which also results in less flickering when setting up the keyboard extension. It also improves layout rendering by enabling layout caching by default. The old experiment has been converted to a proper dynamic KeyboardSettings setting. We hope you'll like these new changes.

This version also adds a new KeyboardSettings setting to visualize the dynamic text tap areas, to make it possible for developers to verify this dynamic behavior.
