Posts for the month of May 2015 is now HTTPS-only is now configured to serve all traffic over HTTPS. You likely won't notice any change, HTTP URLs will redirect to HTTPS.

Your Subversion working copies will need to be relocated if checked-out over HTTP. In that case an error like the following will be seen:

svn: E175011: Repository moved permanently to ''; please relocate

The working copy can be fixed using svn relocate:

$ svn relocate http:// https://

For Subversion < 1.8, you'll need to use svn switch --relocate instead.
