- Notes on upgrading from an older release
- ========================================
- 
-+o Upgrading from a version prior to the post-1.8.15 fix for CVE-2015-5602.
-+
-+    The meaning of the sudoedit_checkdir sudoers option has changed.
-+    Previously, it would only check the parent directory
-+    of the file to be edited.  After the CVE fix, all directories
-+    in the path to be edited are checked and sudoedit will refuse
-+    to follow a symbolic link in a directory that is writable by
-+    the invoking user.
-+
- o Upgrading from a version prior to 1.8.15:
- 
-     Prior to version 1.8.15, when env_reset was enabled (the default)
