+The APR DBD Driver for FreeTDS has been removed from the build.
+It is known to have problems, and we are not able to maintain it.
+
+The source code is still available.  If you want it and are able
+to manage maintenance for yourself, you can patch the build and
+work through issues that affect you, but you're on your own.
+
+We expect that for most users, the ODBC driver will serve as
+an alternative.
+
+Sorry.
