From what I can find, the last release was Version: 1.0.27 Release date: 2007-05-16.

If I have this correct, what is the explanation for this? It would appear that support has stopped.

No it does not mean that support has stopped. The service is regularly updated (usually once a month).

The lack of release announcements can be explained (only partially) by the fact that in July we migrated our forum to the Beast and the process of back porting release notes somehow stuck and this caused also that new release announcements have not been published.

We will correct that and new releases will be regularly published on this Forum.

New release just went live
