Linux continues its relentless development. The open source kernel does not rest, and regular developers, such as those who contribute code from time to time, have done a great job of resulting in the Linux version 5.7-rc4. That is, Release Candidate 4, one of the candidates on the way to the final version.
As usual, the person in charge of presenting this new version has been Linus Torvalds. This makes it clear that this Linux 5.7-rc4 is now available for download and test, if you don't want to wait for the final. And everything seems to indicate that the development was normal, with nothing out of the ordinary. The only noteworthy thing is the size of the kernel ...
Some versions exceed the average size because a lot of code has been added, especially new drivers, and at other times the kernel is somewhat smaller (as is usually desired). In this case, it is one of those situations where it has been a little smaller than usual, which is not bad news.
One of the reasons it's smaller is that there was no code input for the networking subsystem, for example. But there have been contributions in terms of other drivers such as GPU, DMA, sound, rdma, virtualization for Hyper-V, md, i2c, and mmc. Of course misc also had some fixes and was contributed in the realm of filesystems (btrfs and NFS). There have also been some code contributions referring to CPU architectures, such as RISC-V and ARM64, as well as crypto, etc.
It is expected to appear shortly a new rc5 kernel, with some improvements. We will see what happens with that development that is being forged at the moment and all that this Linux 5.7 can give of itself ...
