Hi!
I'm announcing the release of the 4.19.325 kernel.
It's the last 4.19.y release, please move off to a newer kernel version. This one is finished, it is end-of-life as of right now.
We (as in CIP project) will keep this one maintained for few more years, in a similar way we already maintain 4.4 tree.
https://gitlab.com/cip-project/cip-kernel/linux-cip/-/tree/linux-4.4.y-st?re...
There are -st trees, which is simply continued maintainence of 4.4 and 4.19 stable trees. Plus we have -cip trees, which include that and support for boards CIP project cares about. We'll also maintain -rt variants of those trees.

It's likely important to note in this context again that CIP kernels are maintained with a focused scope to address the needs of industrial use cases. This is guided by input from our project members but also includes broader community contributions.
For the 4.19 kernel, we prioritize support for x86, arm, and arm64 architectures (since 5.10-cip, also riscv). We actively track vulnerabilities, fixes, and backports for components identified through the selected kernel configurations contributed by our members [1]. This configuration-based support already helps to filter out a good share of CVEs, and we are working on tooling to further compensate missing fixes tags or other lower boundary annotations [2].
At this chance: The CIP project has also selected the 6.12 kernel for providing extended long-term support of up to 10 years. That will be the 5th kernel we are maintaining, after 4.4, 4.19, 5.10 and 6.1.
For newer kernels, the CIP maintainers additionally accept backports of hardware-enabling commits that went upstream only in later releases and that are non-invasive to the surrounding drivers and subsystems.
Contributions are warmly welcome, from test reports, over patches, up to joining our project!
