Linus Torvalds has announced the sixth release candidate (RC6) of Linux Kernel 6.13 on January 05, 2025. Linux kernel 6.13-rc6 marks a return to normalcy following the holiday season. While commit activity remains lower than usual, it's expected to pick up as developers return from their breaks. The changes in rc6 are primarily driver updates and bug fixes, with no significant issues standing out.
In the Kernel 6.13-rc6 release announcement mail, Linus Torvalds noted:
"So we had a slight pickup in commits this last week, but as expected and hoped for, things were still pretty quiet… I expect things will start becoming more normal now that people are back from the holidays and are starting to recover and wake up from their food comas."
