Linus Torvalds, through the LKML, has published another new piece of news about the development of the free and open source kernel. This is the new final candidate version. Specifically, it is Linux 5.7-rc5, which is nearing the end of development to obtain the new version of the kernel that you will be able to install shortly on your favorite GNU / Linux distro with all the news. However, if you want to try it now, you can try this Release Candidate.
Of course, you should not remove the current kernel version you have, since it is not a final version and could have some problems that remain to be polished. You know, and I think it is not necessary to repeat it over and over again, that you you can download from the official website for this Proyect: kernel.org. Same place where you will find other versions of the vanilla kernel like the stable one at the time of writing: Linux 5.6.12.
As for the the news Linux 5.7-rc5, the truth is that as stated in the email that has been released, it is a version without too many problems or shocks for developers and unlike the previous release, this time it is somewhat less than average. Which is not data that should be taken as something negative or positive, although if it is more compact, the better ...
In the previous rc4, it had a size below normal, most likely due to the lack of drivers in the network stack that is usually common. Among the changes that this rc5 brings, some contributions are included in that regard. So the larger size is something to be expected. In addition to those changes, there have also been other contributions and corrections. However, there are changes here and there, without any special section in which the contributions stand out.
By example, you can find improvements in the network drivers as I have already done, updates for the code dependent on certain architectures such as RISC-V, in the aspect of virtualization such as kvm, tools, documentation, etc.
