I'm particularly happy to see keyboard shortcut preferences in the release notes, that's been a real pain point.
Thanking you kindly, sir.
I also like the new QuickStart Cards as a way to get started that doesn’t require reading the built-in tutorial.
Instead v5 officially supports AppImage builds.
As a summary - friendly as in better autocomplete, better error messages. There are vast accessibility improvements for those with low vision and those that use screen readers. It’s more fun for many reasons but stand out ones are support for game controller input, interactive docs and low-friction QuickStart cards.
