Attention #inkscape testers. While we wait for an actual alpha release, you can use the downloads which I've just fixed the links for here: https://inkscape.org/release/inkscape-1.4.x/
I recommend using the AppImage if you're on #linux and the dmg/7z files should be fairly straightforward for other operating systems.
Oh, and thanks, user #testing is still the main way Inkscape finds bugs before releases while we work on building our test suites. ❤️
