La next Linux version it will be very normal, nothing big or with dramatic changes. It will have 50% of the code destined for controllers, which is what it occupies the most, with 10% dedicated to architectures, and 20% shared between documentation, networks, file systems, updates to the header files or headers, and the actual kernel code as such. Therefore, everything is very normal, with the development step by step as it has been doing so far.
The only notable change is the numerology, since a Linux 4.21 will not arrive after Linux 4.20. He already said it a few months ago, and now it has been confirmed, the new version of 2019 will be called Linux 5.0. Now Linux 5.0 RC1 is being developed, which if I continued with the previous numerology should be RC1 from 4.21 as I said. This has been confirmed by himself Linus Torvalds at the LKML.It has not occurred due to the amount of million objects in Git as hinted, reaching a round number and taking advantage of that event to change the numerology. In this case it has not been done like that, Linus has simply joked about the lack of fingers on his body to count beyond 20. «If you want an official reason, I ran out of fingers to count, so 4.21 became the 5.0 ». As they say: new year, new life. In this case, new year and new version.
Some blogs, as you can see if you search by Google, they assumed that version 4.21 would exist, and the change would not occur as expected. But it has not been like that, the new 5.x numerology arrives just when expected. So users will have to get used to calling it like that from now on and leaving behind number four, which is now a thing of the past ... If you want to read the full note, you can click here.
