Hi,
We receive your newsletter notifying JomSocial 3.2 RC1
This upgrade is just for JomSocial Standard? Have you not done any upgrade/updates for latest JomSocial Pro 3.1.1?
RC means it is a Release candidate version which is not to be installed on a live / production site. These versions are only for reporting / testing therefore they are always the standard version. Once Jomsocial is released as a final stable version then all licence types will be the new version
