 Notes on upgrading from an older release
 ========================================
 
+o Upgrading from a version prior to 1.8.7:
+
+    Sudo now stores its libexec files in a "sudo" sub-directory
+    instead of in libexec itself.  For backwards compatibility, if
+    the plugin is not found in the default plugin directory, sudo
+    will check the parent directory default directory ends in "/sudo".
+
+    The default sudo plugins now all use the .so extension, regardless
+    of the extension used by native shared libraries.  For backwards
+    compatibility, sudo on HP-UX will also search for a plugin with
+    an .sl extension if the .so version is not found.
+
+    Handling of users belonging to a large number of groups has
+    changed.  Previously, sudo would only use the group list from
+    the kernel unless the system_group plugin was enabled in sudoers.
+    Now, sudo will query the groups database if the user belongs
+    to the maximum number of groups supported by the kernel.  See
+    the group_source and max_groups settings in the sudo.conf manual
+    for details.

 o Upgrading from a version prior to 1.8.2:
 
     When matching Unix groups in the sudoers file, sudo will now
     match based on the name of the group as it appears in sudoers
     instead of the group ID.  This can substantially reduce the
     number of group lookups for sudoers files that contain a large
-    nummber of groups.  There are a few side effects of this change.
