Comment 32 for bug 578045

Applications in Software Center now are mostly apps that users want to keep up with the latest version. For these apps in Software Center. I suggest using a similar system like bundles in Chakra Linux. Those bundles are one-click installable archive like in Windows or Mac. And these bundles don't interfere with the existing system since all dependences are packaged into the bundle. This way the base system can be kept stable and apps can be easily updated. This way Ubuntu should support LTS versions even longer and stop release unstable versions every 6 months.
I believe it's an easier option than backporting new version of apps that depend on newer libs that may interfere with existing old version libs.
Hope some developers may take some time and look into Chakra 's bundle system.
If it's too hard to change release model of Ubuntu , I hope someone would implement such feature independently as a new distro based on debian.
