There is one user (sysadmin) visible change in 2.2.19-2 to the a2enmod command's output:
-info("To to activate the new configuration, you need to run:\n /etc/init.d/apache2 $reload\n")
+info("To activate the new configuration, you need to run:\n service apache2 $reload\n")
I've verified that the output string does not show up in the current version of the Ubuntu Server Guide, and contacted the person working on the apache portion of the Ubuntu Server Guide according to http://

Attached is a debdiff for the merge of apache 2.2.20-1 (I was unable to do this via bzr due to bug 842144). I've verified that the package builds on i386 and amd64 and ran the lp:qa-regression-testing tests against that package, and confirmed that no regressions occur.
