http://www.w3.org/community/webed/wiki/HTML/Specifications shows, that current version of HTML is 4.01 and version 5 is in draft only...but in the same time everybody is proving compliance with it. Big fun...that we're all using beta version of something and we're happy from it :)
In mean time I have resolved some jQuery/jQuery Mobile issues and currently you can search inside Przepisy Drogowe and make various things.... there are still some issues with it, but they're connected with HTML (HTML5 ?) problems - you don't have frameset, iframe doesn't allow to use % (I have used it, but....), you can't easy scroll to some place before page is displayed, etc.
Anyway, new www, Tizen and Firefox OS versions for Przepisy Drogowe were released - some immediately (www), some are waiting for certification second week (Firefox OS), some will be probably displayed, when shop will start (Tizen).
