**PAM Changes** - The pam_krb5 and pam_ksu modules have been removed as part of a PAM update. If you were using these modules, the security/pam-krb5 package in pkgsrc is a suitable replacement.
+**crypt(3) / master.passwd changes** - Improved crypt routines have been implemented as
+part of this release. New installations will use sha512 format passwords, with improved
+hashing available for the previous sha256 default. Legacy binaries reading password
+entries will need to be rebuilt in order to authenticate against the new hashing schemes.

**Remaining issues** - The DragonFly bug tracker mentions some issues still known but not fully diagnosed at time of release. Specifically, building world with more than 4 processes (-j 5) may cause issues on i386, and some users have seen issues with NFS. Check the [3.0 release ticket](http://bugs.dragonflybsd.org/issues/2286) for details.
