I've been wondering why the ubuntu's version of chromium is still on 25 -- from lucid up until raring -- while the current stable version is 28. The only reason I use chromium is to use the web apps integration.

PS : I have tried to use the web apps integration on another version of chromium -- not google chrome -- which is 28 then it seems that some features I use was lost while using other version than 25.

EDIT: Sorry I forgot to tell you I use the 13.04 version and also the development branch 13.10. My question was : Why does ubuntu doesn't update the package in the repository to the current stable version?
