That mean bug not gonna solve inside this version ?
Ubuntu releases a version then just fixes bugs of a program.
Eg. Take Libreoffice...
Version x might ship with Libreoffice 3.4.x
Even if the Libreoffice 3.5.x series comes out 1 month after Ubuntu Version X, they will not let you update to it. They will only let you get newer bugfixes, no new features.
You will have to wait for Version x+1 for Libreoffice 3.5.x series.
