This has been a great week, especially for Ubuntu fans, due to the release of Ubuntu 21.04 and all of its official and unofficial flavors. On top of that, Mozilla released the Firefox 88 web browser, KDE Project released the KDE Gear 21.04 software suite, and Linus Torvalds released the Linux 5.12 kernel. This week also saw new releases of the Tails anonymous OS, Oracle’s VirtualBox virtualization platform, and the Geary email client. I top that with a first look at Firefox 89’s refreshed interface and other changes coming this summer. You can enjoy these and much more in the 9to5Linux Weekly Roundup for April 25th, 2021, below!
