4JStudios has announced that it will be posting a changlog for TU12 after it has been approved by Microsoft's certification testing process for Minecraft Xbox 360 Edition.
In a series of Tweets on their official account 4J commented, "We're still working on TU12 – there are lots of software architecture changes needed for this update. Thanks for your continued patience. ;)"
This was followed by, "We're bug-fixing TU12 at the moment. Lots more bugs to fix… We'll let you know when it goes to Microsoft Cert Test."
And finally, "We'll post a change list for TU12 once we put it into Microsoft Certification testing."
Quite when the update, and the changlog, will go live is unclear but hopefully it won't be too far away.
What changes or fixes are you hoping to see as part of TU12? At E3 last month, Minecraft was also announced for the Xbox One and Microsoft are "discussing" the ability to transfer save files between the two versions.
