The main improvements are fixes around key handling, especially a regression in the snappiness of ESC.
A feature was added to support filling/clearing just a portion of the screen as well.

Full Changelog: v3.4.0...v3.4.1

This release has quite a number of bug fixes, but it also introduces some substantial new capabilities.
Mostly the new support for advanced key reporting, along with backing support in the mouse demo, and
enhanced configurability and overrides both for the application and for the user (environment variables).

This also replaces the old WASM terminal with a new version based on the libghostty implementation. This
should be much faster, and nicer to work with, with a larger set of full features such as advanced key reporting,
better support for resizing, etc.

Full Changelog: v3.1.1...v3.1.2

This fixes two bugs, both involving wide characters (including emoji) and terminal bugs.

Full Changelog: v2.13.7...v2.13.8

This principally fixes two bugs:

• Certain runes would cause problems if pasted on Windows (could hang, wouldn't pass) due to Windows surrogate pair handling (#986)
• Certain terminal emulators would give unfortunate results with certain wide characters (#976)

A bunch more progress made on the emulator subsystem as well, but its still not quite ready for public consumption, although it is used in the mock for testing tcell.
