Option to send group messages to individual recipients also included
Hangouts is making the subtle jump to version 2.0.2, bringing fixes for the way the messaging app handles MMS. Although the issues haven't necessarily been widespread, many who have updated to the latest Hangouts and began using it for text messaging have been running into issues sending and receiving MMS. While this update doesn't specifically go into what the issue was or how it's being fixed, folks who have been having trouble with MMS in Hangouts should be doing better after the update.
MMS isn't just used for pictures though, it is also used for group messaging. Tied into this update is also a new option to turn off MMS group messaging if you'd prefer to have your messages sent to multiple recipients individually.
