NetBSD 6.1.4 is the first security and bug-fix update of the project's 6.0 branch: "The NetBSD project is pleased to announce NetBSD 6.0.1, the first security and bug-fix update of the NetBSD 6.0 release branch. It represents a selected subset of fixes deemed important for security or stability reasons. Please note that all fixes in security and bug-fix updates (i.e., NetBSD 6.0.1, 6.0.2, etc.) are cumulative, so the latest update contains all such fixes from the corresponding minor release (in this case, 6.0). Major changes: posix_spawn() - fix processes with attributes; resolve races between vget() and vrele() resulting in vget() returning dead vnodes.
