Badlion, a very popular Minecraft launcher that bundles a bunch of things together, has been officially transferred to Linux with the Badlion Client 3.1 update.
What's the significance of it? Well it offers up select additional features straight out of the box including enhancements such as Optifine and their own "Betterframes" tool, anti-cheat (not in the Linux version) as well as various tweaks to improve FPS improvements and a variety of mods are available, including Minimap, ArmorStatus, PotionStatus, Crosshair, CPS (clicks per second) and many more. A lot of people use it, so it's good to have options on Linux official like this.
This is how it looks as it appears on Linux. First , the launcher itself and the second is an in-game picture with their own menu system.
In relation to the Linux release, they said:
We are thrilled to announce today that the Badlion client is now accessible for Linux users. Over the past few months, our development team has been working hard to finish the final pieces of Linux support. This includes resolving the compatibility issues we talked about in our announcement post about Linux last year. The team of developers was able to complete the Linux support just in time for BLC 3.0.
We would like to express our gratitude to the Linux community and their patience during the past few months. We are aware that we were not unfortunately in a position to release the Linux version until the end of 2020 like we had hoped, however we hope you're excited nonetheless to test the most feature-rich Minecraft version available for free!
