There is no "HTML5" yet; there is only a discussion about a possible future specification.
To see examples of various features of the WhatWG "HTML5" proposals, try http://www.html5gallery.com/ .
The most recent version of HTML is HTML 5. 5, however, is still a W3C draft (meaning they haven't finalized it.) At the present time, it seems unlikely that this will ever occur. (Instead, the W3C will likely create a language to supersede HTML 5.) The last set of accepted changes to the HTML 5 specification was on 29 March, 2012. The most recent complete version of an HTML-like language was XHTML 1.1. It was last changed 10 November, 2010.
The whole Doctype tag in html 4 is shortened in html 5. Say in html 4 you saw some code like this at the top: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> Now you just use <!DOCTYPE html>
The HTML 5 specification recommends using <strong> for bold text and <em> for italicised text. In HTML 4.01 <strong> defines both strong and emphasised text; for purely bold text, use <b> instead (in HTML 5, <b> and <strong> are equivalent).

it think the versions are HTML 1.0 HTML 2.0 HTML 3.0 HTML 3.2 HTML 4.01 xhtml 1.0 and now HTML 5 The different versions are used to characterize changes in the HTML itself. With new features and new tags come new versions. In the modern web, (HTML 4+) the versions are also the basis for laying out standards that describe the function of the HTML and how the browsers are supposed to display it. For instance, prior to HTML 2.0, there were no images available in HTML. If you're interested, the W3C (World Wide Web Consortium) is in charge of keeping the current HTML and XHTML standards. You can find the specific changes in versions on their website.
