Not sure what you are referring to as "the original one" but these are Helix builds, not Gotham, and contain several improvements such as a more recent ffmpeg, plus (in theory) better database performance during scrapes and updates. Also on the newclock4 builds there is no longer a distinction between omxplayer and dvdplayer, so more media should play correctly without you having to choose the appropriate player. A summarised changelog is in the first post (against each release), drill down into the release posts for full details.
