Following their success in stripping out the remaining Python 2 bits, the release candidate of OpenMandriva Lx 4.0 is now available.

While open-source operating system projects derived from the former "OpenSolaris" code now maintained by the Illumos community aren't exactly prolific these days, one of the projects that does continue cranking through and seeing commercial success as well is OmniOS. OmniOS r151030 was released this week in its "Community Edition" flavor with various improvements.

While many other Linux distributions are still in the process of demoting Python 2 packages out of their main archive / base OS ahead Python 2 being EOL'ed at the start of 2020, OpenMandriva Lx 4.0 has now joined the class of Linux distributions having already succeeded in that tangled effort.

Jolla released Sailfish OS 3.0.3 "Hossa" as the newest feature update to their mobile Linux OS. With this update they've begun a number of much-needed low-level improvements to their platform.

The Haiku operating system that continues to be the open-source project living on in the traditions of BeOS is continuing to advance its modern hardware support and application compatibility.

The Netrunner Rolling Linux distribution that is based on Arch Linux / Manjaro (unlike the non-rolling release using Debian Testing) is out with a new release for this KDE-focused desktop platform.

Back during the BeOS days of the 90's, NVM Express solid-state storage obviously wasn't a thing but the open-source Haiku OS inspired by it now has an NVMe driver.

GentooLTO is a configuration overlay for Gentoo's overlay to make it easy to enable Link Time Optimizations (LTO) and other compiler optimizations for enabling better performance out of the Gentoo packages. GentooLTO appears to be inspired in part by the likes of Clear Linux who employ LTO and other compiler optimization techniques like AutoFDO for yielding better performance than what is conventionally shipped by Linux distributions. The GentooLTO developers and users have wrapped up their survey looking at how practical this overlay configuration is on the massive Portage collection.

It's approaching two years since the release of Mageia 6 but at least the wait for Mageia 7 shouldn't be too much longer.

CentOS, the community enterprise operating system built from the sources of Red Hat Enterprise Linux, is marking its 15th birthday.

The Raspberry Pi Foundation has released a new version of Raspbian, its Debian-based operating system for Raspberry Pi devices.

Mer, the fork of MeeGo that aimed to provide a free alternative to Maemo for Nokia devices, is now finally merging with Sailfish OS.

It's been a while since last having any major news to report on Sabayon Linux, the once quite popular Gentoo-based Linux distribution, but they ended out March with a big update as version 19.03.

OpenMandriva has been toying with some performance optimizations in recent times like preferring the LLVM Clang compiler over GCC, spinning an AMD Zen "znver1" optimized version of the OS/packages, and apparently now exploring possible Profile Guided Optimizations.

For those trying to keep to a systemd-free system, Gentoo developers have GNOME once again working without being dependent on systemd. The developers have managed with GNOME 3.30 the ability to use any init system desired, well, primarily OpenRC as is popular with Gentoo users.

Jolla has announced the release today of Sailfish OS "Oulanka" as their version 3.0.2 update.

Solus 4 has officially set sail as the latest version of this popular desktop Linux distribution that is known for its "Budgie" desktop environment, borrowing some performance optimizations from the likes of Clear Linux, and various usability enhancements and more to enhance its desktop experience.

Knoppix, one of the first "live" Linux distributions that dates back to the year 2000 and still continues to see occasional updates, is out today with Knoppix version 8.5 in celebration of the latest Chemnitzer Linux Days event.

The BeOS-inspired Haiku operating system now has good USB3/XHCI support in place with their latest daily snapshots.

Purism announced this morning that their PureOS Linux distribution for their Librem laptops and forthcoming Librem 5 platform has achieved the goal of "convergence".

Developers persisting on Haiku as the BeOS-inspired open-source operating system made more headway in February to advance their OS past the recent (and successful) beta milestone.

ReactOS 0.4.11 is now available as the newest version of this open-source operating system re-implementing the Windows APIs with a focus on binary driver/application compatibility. With this being the first release since November's ReactOS 0.4.10, there are a fair amount of changes to find in this new build.

It's been a while since last having anything significant to report on Redox OS, the Unix-like operating system written in the Rust programming language and pursuing a micro-kernel design, but fortunately this open-source OS is still moving along and they have some interesting plans moving forward.

Gentoo's Linux kernel build has long offered various CPU options in allowing those building their distribution to optimize their kernel build to the CPU being used. Every so often the patch is suggested for upstreaming to the mainline Linux kernel before being quickly rejected by the upstream maintainers.
