The Wedding Anniversary Release

A hotfix

[0.79.1] - 2024-08-31

Fixed

• Fixed broken updates when non active screen changes #4957

The Query faster Release

This release optimizes query_one and changes the semantics a little. query_one will no longer raise a TooManyMatches if there is more than a single widget matching the selector. For the old behavior, you can use the new query_exactly_one method.

The Push it to the Max Release

This release adds a new maximize method, which you can use to temporarily full the screen with any given widget. This can be great for allowing the user to focus on a particular view.

You can maximize via the command palette, or you can bind a key with the action screen.maximize.

Here are some screenshots of this feature in action:

[0.78.0] - 2024-08-27

The lucky number 77 release

This is quite a large release!

We've done a lot of work on the command palette to make it easier to work with and use.

We've also added a "help panel" which you can summon from the command palette. This will give you context sensitive help, and a summary of all the key bindings. Here it is in action:

Screen.Recording.2024-08-22.at.15.13.22.mov

Also in the command palette is a "save screenshot" command, which will save a screenshot of the current screen. Very handy for adding to documentation.

There are a number of other smaller changes, fixes, and a few breaking changes. See the detailed release notes below:
