The lean application framework for Python. Build sophisticated user interfaces with a simple Python API. Run your apps in the terminal and a web browser.
The highlight of this release is the new inline feature, which allows you to run Textual apps below the prompt, rather than in application mode.
We also have a bunch of additional languages for the TextArea widget, and some fixes.
