+- Update to release 2.25
+  * mt2exm: the -B option can be used with all folder names
+  * mbop: new commands ``get-photo``, ``set-photo``,
+    ``get-websettings``, ``set-websettings``
+  * oxcmail: export no longer generates a MIME epilogue, which
+    should workaround Outlook's broken S/MIME validator which
+    fails to include epilogues in the signature verification.
+  * mkpublic: newly created public stores lacked a
+    ``replguidmap`` table
+  * exmdb: repair initialization of PR_ATTACH_NUM when instances
+    are opened
+  * oxcmail: strip leftover right angled bracket from Content-ID
+    on oxcmail_import
