That’s right, Linux 4.20 is the next kernel coming after Linux 4.19, which was released by Greg Kroah-Hartman on October 22,2018, not Linux 5.0 like many of you out there where hoping to see this year. Linus Torvalds decided it’s best to end 2018 with Linux 4.20 and release Linux 5.0 in 2019. As the two-week merge window closes, the first Release Candidate (RC) of the Linux kernel 4.20 hits the streets to mark this series as ready for public testing. According to Linus Torvalds, Linux 4.20 had a ???fairly big??? merge window, but then again it was not a record breaker.
