Shotwell 0.23.2 is now the latest and most advanced stable version of the project, bringing better support for the Facebook integration by adding a pop-up login and updating the documentation in regards with the Facebook publishing permissions. When Shotwell 0.23 was released, users reported that scroll bars were missing from events, so that is fixed in the 0.23.2 point release. Moreover, starting with Shotwell 0.23.2, the gphoto 2.4 library is no longer supported, and libgee 0.10 or higher is required.
