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.
