- It is now possible to recall the most recent settings used when creating a font asset in the Font Asset Creator.
- Newly created font assets now contain the settings used when they were last created. This will make the process of updating / regenerating font assets much easier.

- Updated package license.
- Non-Breaking Space character (0xA0) will now be excluded from word spacing adjustments when using Justified or Flush text alignment.

- Updated Font Asset Creator Plugin to allow for cancellation of the font asset generation process.
- Added callback to support the Scriptable Render Pipeline (SRP) with the normal TextMeshPro component.
- Improved handling of some non-breaking space characters which should not be ignored at the end of a line.
