NetBSD, a free, fast, secure, and highly portable Unix-like Open Source OS available for a wide range of platforms, from large-scale servers and desktop systems to handheld and embedded devices, is now at version 5.1.2.
NetBSD 5.1.2 comes with a lot of changes, but most of them are fixes regarding OpenSSL, BIND, Kernel stack overflow, LZW, and OpenPAM.
The distribution also comes with a few Linux kernel fixes that could lead to filesystem corruption and panics or affect the stability.
Unfortunately, NetBSD 5.1.2 has some known problems. Using block device nodes directly for I/O may cause a kernel crash when the filesystem containing /dev is FFS and is mounted with -o log, gdb may cause a process that is being debugged to hang when "single stepped", and Statically linked binaries using pthreads are currently broken.
A complete list of the changes can be found in the official announcement.
