This is unconfirmed news but the screenshots look legit.
It appears as though the installer will get some new functions.
The most profound change we can see in the screenshots is a new search function.
Cydia already had this feature, but as installer is still the the preferred install program, this new search will be cheered upon by many of us users.
The Installer 3.1 release date isn’t public knowledge yet, but my guess is that it’s going to be reallly soon.

Here some screenshots
