-5.1 is dedicated to the memory of Martti Kuparinen, who
-was the victim of a traffic accident in June 2010.
-.Pp
-Martti's technical contributions are too many to list here in full.
-He created and maintained numerous packages in pkgsrc, updated two
-packet filter solutions distributed with
-.Nx
-and improved several
-hardware drivers. Beyond that he was always helpful and friendly. His
-example encouraged users to contribute to the project and share their
-work with the community. Some of these users later became
-.Nx
-developers themselves thanks to Martti's efforts.

-.Ss Changes Between the NetBSD 5.0 and 5.1 Releases
-.Pp
-The
-.Nx
-\*V
-release is the first feature update of the NetBSD 5.0 release branch.
-It represents a selected subset of fixes deemed critical for security or
-stability reasons, as well as new features and enhancements.
-.Pp
-Please note that all fixes in security/critical updates (i.e., NetBSD 5.0.1,
-5.0.2, etc.) are cumulative, so the latest update contains all such fixes
-since the corresponding minor release.
-These fixes also appear in minor releases (i.e., NetBSD 5.1, 5.2, etc.).
