Earlier this month, the team behind Linux Mint released Linux Mint 21.3 for download after about one month of beta testing. Unfortunately, it included an older Long Term Support kernel which doesn’t support some newer hardware; the new Edge ISO should overcome this problem.
The main Mint release includes Linux 5.15 but the new Edge edition includes Linux 6.5. Linux 5.15 has been available since October 2021, while it has received security patches since, added hardware support has not been added, therefore, people with newer hardware need to run a newer kernel like the one offered in Edge.
One caveat that the team mentioned in the Linux Mint user guide is that the Edge edition may not be as stable as the other ISOs and may not support as many proprietary drivers. It recommends that you should only use the Edge ISO if you can’t boot or install Mint with the other ISOs.
Linux Mint 21.3 initially got released on January 12, after a phase of beta testing extending over a month. The extended phase of testing resulted in the upgrades being feasible on the day of launch too.
The Edge ISOs that are released just now have been under testing for a significant period. The first ISO that underwent testing did not pass, pushing the team to conduct a second round of tests, which was successful.
Contrary to the Debian-based LMDE, this Edge version of Mint continues its base on Ubuntu – making it parallel to the hardware enablement releases typically pushed by Canonical for Ubuntu. Being Ubuntu-based, this version will also be subject to updates till 2027 similar to the other Mint 21.x versions.
Linux Mint 21.3 brings a host of upgrades including comprehensive secure boot support, improved compatibility with multiple BIOS and EFI implementations, enhancements in Hypnotic, and Cinnamon 6.0, which is loaded with new features.
To get Linux Mint 21.3 Edge or any other versions, just head to the Linux Mint website and browse the downloads.
