This new release doesn’t bring new features but it’s an important one since it supports PackageKit 0.9.x API, also this is the first release which uses the first 100% async calls on PackageKit-Qt.
Making Pk-Qt sync-free wasn’t so complicated but since I had to rethink the API the client code of Apper also needed to be adapted, I must say that I was lazy sometimes and just created a QEventLoop in Apper to wait for the reply… and this basically means that there will be new bugs in Apper, and hopefully some will be fixed.
It’s interesting that using DBus doesn’t means the code talking to it is async, the proxy classes generated by qdbus2cpp do a blocking call everytime you ask for a property, so you have to avoid it and do a GetProperties call which returns to a callback, although this worked well for PackageKitQt I failed to do the same for libnm-qt, and that is because it’s nearly impossible to make it somehow reliable due to NetworkManager itself not using gdbus, so you can’t have a reliable snapshot of it, unless you do an introspection call which is also insane, so I prefer to wait for when they switch to gdbus :P
Apper 0.9.0 depends on Qt4, KDE4 libs and PackageKitQt 0.9.2.
I’m not giving it much attention lately since I’m slowly building Apper on Qt5 which will be using QtQuick2, as my time is short supporting this old version is mainly to make packagers happy :)
