Sammobile, the best known source for firmware leaks from Samsung who recently leaked the Official OTA Jelly Bean updates for Galaxy Tab 2.7.0 and Galaxy Note 10.1 has leaked yet another most stable Jelly Bean firmware for Galaxy S3 which is I9300XXDLI5 minutes ago. About this leak, Sammobile says:

This build is very much near perfect so we believe that Samsung will actually start rolling out the Official Jelly Bean update for the Samsung Galaxy S III very soon. The day Samsung starts to roll out the official update you will be able to install the latest update through Kies or OTA update. We are getting leaks almost everyday so we believe that the final Official Jelly Bean update will be released in the next week. 
I9300XXDLI5 Noticeable Changes:
