I think it is a nice touch from Unlocker that they list extra "Promotional features" in changelog. Most do not, almost seems like they would not want you do take too much notice - just click, click ;) Unless installation is set up to trick users into clicking wrong buttons or make them dizzy with too many unrelated windows, information of process should take away most annoyances. He does not highlight it that much, not like Registrybooster crap, and may be it will vanish after next update since no longer news but under the circumstances which is 2011 internet and almost everything goes, it is better than nothing. These sometimes sneaky marketing add-ons should be part of license policy for program. Should be mentioned right next do download link. Then anyone know what to expect and cannot claim X program secretly hijacked search box in browser or other evils.
Notice how he melts Registrybooster in to download section
http://cedrick.collomb.perso.sfr.fr/unlocker/#download almost as part of his site. Old trick and a hint of how he look at marketing towards users and what to expect ;) 30 sec timer is just his way of annoying you in his defeat. Still think it is good he give a little mention of promotional features.
