What is a linux RC0 Manjaro kernel package if it's version family is absent and never existed?

Support Kernel

The unstable branch of updates.

As I know the RC0 version is officially never exist as general Linux kernel version. It is Manjaro Linux related stuff.

As example:
Current US date is: Saturday, June, 27th.

The RC1 of the 7.2 kernel family is expected on the next day: it is not ready and the Linus repo could get many payload commits before the brand new 7.2 family and it’s RC1 will appear.

The kernel.org website shows:

mainline:	7.1	2026-06-14
stable:	7.1.2	2026-06-27
stable:	7.0.14 [EOL]	2026-06-27
longterm:	6.18.37	2026-06-27
longterm:	6.12.94	2026-06-19
longterm:	6.6.143	2026-06-19
longterm:	6.1.176	2026-06-19

the Manjaro Settings Manager shows that the never-existed kernel version of 7.2-rc0 is available to install.

So what is the RC0 Manjaro kernel in every family version and how do I know the exact commit it was based on?

Could it be out of date comparing with even any stable kernel version (in the case of 7.2-rc0 if to compare it with the current stable 7.1.1?

How old the codebase of such RC0 Manjaro kernel versions generally are?

I understood that it is the very early preparation step to build the upcoming brand new family versions of release candidates, but I wanna know details to understand to decide for me: to use any of such Manjaro RC0 kernel versions or better to wait the RC1 in each kernel family.

Thank you!

Take a look here

I guess that is what you look for

Before 7.2-RC1 is released, updates to the 7.2 kernel are already being published. Even though these aren’t officially called RC0—not even on kernel.org—they are, technically speaking, exactly that.

I refer to all my PRE-RC1 kernels as RC0.

RC0 is usually a snapshot of first weeks merge window. I only publish it when i find time and want to know which extramodules need patching.

To summarize:

So what is the RC0 Manjaro kernel in every family version?

how do I know the exact commit it was based on?

All kernel families have different commits right after they were spitted/forked out from the mainline repo. Because of that it is hard to say “out of date” - they are supported individually some patches comes to all families, some to selected only, some to only one family - it depends - they all are maintained, but differently.
According to the

, the 7.2-rc0 was based on the commit in the main development branch on 22nd of June (the same date as 7.2-rc0 build timestamp is) - some time after the 7.1.0 release. Later that branch of kernel development will get further commits and at some point that whole kernel branch state will be tagged 7.2-rc1. So it is

How old the codebase of such RC0 Manjaro kernel versions generally are?
Exact case of 7.2-rc0 was linked here earlier, and generally

So generally a RC0 has no exact point of slice - it is somewhere inside/during of merge window - the time when developers pushes their brand new features, big patches, obsolete code removal actively. And cause of that, it looks like it is more risky to install a RC0 - it is unstable in terms of Manjaro update branches, while RC1+ looks like testing in terms of Manjaro update branches cause Linus controls code all tests outputs before to mark it RC1+, and during a merge window (so-called RC0 stage) it looks like he is not.

I think our combined answer could be like this.

Thanks to all!

Just adding that linux72-rc1 was officially released at the start of this week:
