The "truly your forgiveness I implore" release.

Hotfix for two issues.

[0.48.2] - 2024-02-02

Fixed

• Fixed a hang in the Linux driver when connected to a pipe #4104
• Fixed broken OptionList Option.id mappings #4101

Changed

• Breaking change: keyboard navigation in RadioSet, ListView, OptionList, and SelectionList, no longer allows highlighting disabled items #3881

The nevermore bug release

A small oversight with the TextArea theme

[0.48.1] - 2023-02-01

Fixed

• TextArea uses CSS theme by default instead of monokai #4091

The "As of some one gently wrapping, wrapping at my chamber door" release.

The highlight of this release is the addition of soft wrapping to the TextArea, which you can see below:

soft-wrapping-demo.mp4

This makes TextArea one of our most powerful widgets. Looking forward to seeing what you build with it!

Note there is a breaking change here. The TextArea now defaults to a multi-line soft-wrapped editor rather than a more code oriented editor. If you want the original behaviour, use the code_editor classmethod. i.e. replace TextArea with TextArea.code_editor.

Also in this release is a new suspend decorator which will temporarily suspend the currently running app and allow you to launch another terminal app (which doesn't even need to be a Textual app).

There are plenty of other fixes and enhancements. See below for the full details...
