It represents a selected subset of fixes deemed important for security or stability reasons, as well as new features and enhancements. Major changes between 6.0 and 6.1: posix_spawn() - fix processes with attributes; resolve races between vget() and vrele() resulting in vget() returning dead vnodes; prevent crash when unsupported fd's are used with kevent; fix a bug where kmem_alloc() could be called from interrupt context; WAPBL - coalesce writes to the journal to speed up wapbl_flush() on raid5 by a factor of 3 to 4...."
