NetBSD 6.0 was released last month
with better multi-core/SMP support, the experimental CHFS file-system for flash devices, and other worthwhile enhancements. However, for those not yet ready to jump from NetBSD 5.x to NetBSD 6.0, there is a NetBSD 5.2 release on approach.
NetBSD 5.2-RC1 was released on Wednesday as the first release candidate of a new 5.x release for those not wanting to move to NetBSD 6.x at this time. NetBSD 5.2 adds in various bug-fixes along with some stable new features.
The NetBSD 5.2-RC1 release announcement is available from the netbsd-announce list
Aside from NetBSD 6.0, other recent BSD operating system releases were DragonFlyBSD 3.2 with improved SMP performance against Linux
and OpenBSD 5.2 with new features
while others are just wishing for a unified BSD OS
