Linus Torvalds released the Linux kernel 6.15, which marks the end of support for 486-class CPUs, now only supporting i586 and above. The release saw a significant uptick in development activity with 14,612 changesets, compared to only 11,003 in the previous cycle, signaling a return to robust kernel development. Notably, the kernel will now not allow more than eight x86-32 CPUs in a machine or utilize 32-bit PAE support. Key contributor Kent Overstreet continues improvements on bcachefs, suggesting its increasing maturity.
The 6.15 kernel brought in 14,612 changesets, making it the busiest release since 6.7, indicating a return to full speed in kernel development.
This release drops support for x86 CPUs before the Intel Pentium, effectively limiting the kernel's compatibility to i586 and above.
