[Archivesspace_Users_Group] Container Management plug-in and 1.5 update question

[Tang, Lydia]

Hello!
I just wanted to check on the timeline for the ArchivesSpace 1.5 version to come out?  I recently came across Yale’s cool container management plug-in, which sounds like it would be really helpful for my situation, since we will be sending the majority of our collections to a remote storage while our space is renovated.

Apparently it’s not compatible with the version of Aspace we’re currently running (1.4) and I read that the plug-in will be incorporated into the main code for the 1.5 update, and just wanted to check on its timeline.  Thanks!
