For as great as Linux 5.11 is with its new features , there is also some prominent material that has yet to be upstreamed into the mainline kernel -- some of which is likely to hit in 2021 while other changes have less likely ambitions for mainline.

What is not found in Linux 5.11 include these notable 11 features, if I missed any other pending work worth mentioning feel free to call it out in the comments via the forums:

ReactOS as the long work-in-progress open-source operating system implementation of Windows enjoyed much progress over the course of 2020.

ReactOS over the course of 2020 saw shell improvements, usability enhancements to its application manager, upgrading to GCC 8.4 and CMake 3.17 as its central build components, progress on Clang compiler support (albeit still not yielding bootable binaries yet), the new storage stack was merged, Kernel-Mode Driver Framework support, enhancements to its memory

While development on KDE (and other open-source projects too) was lighter this week as a result of the Christmas and New Year's holidays, the KDE desktop still saw some refinements this week.

On top of the KDE 2021 road-map , developer Nate Graham published his usual weekly development summary of the happenings for the week. Ending out 2020 for the KDE project included work on:

- The Dolphin file manager now supports modifying the context menu to remove items that you are

Valve just published their Steam Survey numbers for December 2020 and it's a huge letdown for Linux gamers if the numbers are indeed accurate.

According to the published numbers from Valve, the Linux marketshare on Steam represented just 0.57%, or a drop of 0.33% compared to the month prior. The December 2020 figures show Windows picking up just over 1.6% while macOS losing 1.31% marketshare down to 2.14%.

While the Linux 5.11 merge window has been over for one week where new features are normally added, a power management pull request sent in today for mainline is adding some tardy features including the Dynamic Thermal Power Management (DTPM) framework that in part is designed to help ensure users don't burn themselves with hot devices.

Rafael Wysocki sent in the New Year's Day power management updates for Linux 5.11. The changes include a crash fix for P-State, new C-states

OpenMandriva Lx 4.1 was released last February while now we are closing in on the release of OpenMandriva Lx 4.2 for that Mandriva/Mandrake-derived Linux distribution.

Back in the summer OpenMandriva Lx 4.1 Alpha was released with an anticipated beta in December. However, after internal testing the developers decided to go straight to a release candidate after being more than satisfied with the quality of the proposed beta. Barring any serious bugs from coming up, the developers expect to release OpenMandriva Lx 4.2 very

The Linux kernel in 2020 saw lots of new features added and other functionality improved while continuing to generally keep pace with punctual new hardware support.

For a look back at the great kernel changes of the past year, for some New Year's Day reading/entertainment, below is a look back at the most popular Linux kernel news stories.

Given the impending release of Linux 5.9, I was having some

KDE developer Nate Graham who has made a lot of contributions to KDE in recent years and is well known for his weekly KDE development summaries has published a 2021 roadmap for the year.

Based on being intricately involved with all things KDE, Nate published a New Year's Day roadmap looking at likely accomplishments for the desktop environment this year.

Among the 2021 roadmap items are delivering on a "production ready" Plasma Wayland session, properly handling fingerprint support throughout the KDE stack, completing the Breeze

New Year's Eve two years ago I wrote about the open-source / Linux letdowns of 2018 . It was well received at the time and sparked some interesting discussions so as we celebrate the start of 2021 I figured it would be interesting to look back and see which of those letdowns were since resolved and what ones are remaining.

From that list at the end of 2018, the items that were since resolved include:
