FreeBSD 15.1 Delayed To Mid-June Due To Critical x86 Bug Fixes

Written by Michael Larabel in BSD on 6 June 2026 at 08:23 PM EDT. 11 Comments
FreeBSD 15.1 was supposed to be out at the start of June but a second release candidate pushed it back by a week and now a third needed release candidate has pushed out the stable release by an additional week.

Last week's FreeBSD 15.1-RC2 release brought a few minor fixes and updates while this third release candidate is more pressing for x86/amd64 users. The only listed change with RC3 are for "critical" bug-fixes in the boot loader / kernel handover code:
"Critical bug fixes to the x86 boot loader / kernel handoff which can cause the boot to hang; this seems to happen most often but not exclusively when Intel microcode updates are being loaded."

That's the only listed change with today's FreeBSD 15.1-RC3 announcement.

Due to two unforeseen release candidates, FreeBSD 15.1-RELEASE is now scheduled to happen on 16 June barring any furhter interruptions to the release cycle. FreeBSD 15.1 is bringing a number of device driver updates for newer hardware support, continued virtualization enhancements, DTrace probes support on PowerPC architectures, the sched_ule scheduler is now implemented as a scheduler instance, removal of Oracle Cloud Infrastructure build targets, updated OpenZFS file-system support, and a variety of packaged software updates.
