[Mailman-Users] Information about Mailman v2.1.7.cp2

Hi all,

I'm about to migrate a number of lists from one server (a thirdy 

party hosting service) to another (my own server) sometime soon. The hosting server runs Mailman 2.1.7.cp2. I plan on installing Mailman 2.1.8 and then migrating the lists to my server.

I searched the announcements lists, Mailman site and Google but I 

couldn't find information about the 2.1.7.cp2 release. Where can I find notes about that release? And what does cp2 stand for?

Thanks in advance.

Regards,

Ricardo
