Happy New Year everyone! I hope you had a safe and fun holiday.
Sugar is getting ready to release version 5.0a, a patch release that addresses several issues in the area of emails, Module Builder, and upgrades (among others). The release should be ready in the next day or so, maybe as early as today.
We are also working on a maintenance patch for 4.5.1 for those folks who are running on that release. Look for that a little later in the month.
