Among the changes decided on were ending their practice of Plasma LTS releases, enhancing the telemetry capabilities to be more useful, and more.

Last year Redis made the much criticized move to Redis Source Available License v2 and Server Side Public License v1 (SSPL) licensing. The move was widely panned by the open-source community and led to the Linux Foundation forking it as Valkey and also other forks like Redict coming about. In the months since many Linux distributions have switched from Redis to Valkey. Now Redis Labs announced today that with the Redis 8.0 release, they are adding AGPLv3 to the licensing mix.

With the recently released GCC 15 (GCC 15.1) compiler besides adding new language features, enhancements to help developers in debugging build failures, and other refinements, there is the never-ending quest of compiler performance optimizations. Since the recent GCC 15.1 release candidate I've been testing this annual compiler feature release on more hardware, including several AMD 5th Gen EPYC "Turin" servers to great success compared to the prior GCC 14 stable series.

Mediatek engineers have proposed Kcompressd as a new addition to the Linux kernel to improve the efficiency of memory reclamation. Mediatek engineers testing these patches on their handheld Linux devices have found huge benefit in alleviating memory pressure and enhancing system responsiveness.

As a follow-up to the Phoronix article a few days ago entitled A Linux 6.15 Performance Regression Hits Modern AMD CPUs, there continues to be activity to address this issue with the performance impact catching the upstream kernel developers off guard. I've tested a patch now that does address the issue while still carrying the KVM protections desired.

During the past month on Phoronix were 249 original news articles and another 23 featured Linux hardware reviews and multi-page benchmark articles. There was a lot of interesting topics in April from the launch of the Framework Laptop 13 powered by AMD Strix Point, an interesting and cheap RISC-V board coming about, the Lenovo ThinkPad X1 Carbon Gen 13 proving to be an interesting low-power Linux laptop, Ubuntu 25.04 and Fedora 42 releasing, and much more.

For those that have spent any length of time in the open-source world have likely come across osuosl.org when downloading open-source projects that often are mirrored at the Oregon State University Open Source Lab (OSU OSL). The OSU OSL over the past two decades has also provided VMs for various architectures from x86 and AArch64 to POWER for CI and testing purposes to open-source projects, among many other support roles. Unfortunately, the OSU OSL risks closure this year.
