0 reply: HTML5 is the fifth revision of the HTML standard, which is not yet completed. Its main goal is to make the Internet semantic so that it can be better read by humans and machines, and provide better support for embedding various media. HTML5 syntax is backward compatible.
But when talking about HTML5, most developers refer not only to this new standard, but to (as Jeremy Keith said)
Doing anything cool (on the web)
The technologies and standards required for doing these "cool" things include some new attributes of CSS3 and some new APIs in addition to the HTML5 standard.
WHATWG announced in March (at least for WHATWG) That HTML5 will be the last version number of HTML, and HTML has become a continuously updated and changing living standard.
All of you mentioned are very good materials. I would like to add some more here:

WHATWG is an unofficial open-source community consisting of employees from companies such as Mozilla, Google, and Opera. It can be attended by anyone. It has made great contributions to the formulation and update of HTML (former HTML5 standard), Web Workers API, and other standards.

The previous descriptions of the relationship between WHATWG and browser vendors are incorrect and have been corrected.
