URL being validated or code to reproduce error:
http://www.ussupernet.com/

Self-closing tag syntax in text/html documents is [widely discouraged](https://google.github.io/styleguide/htmlcssguide.html#Document_Type);

This page has validated with no errors or warnings for years. It uses <!DOCTYPE html>
Starting today, tags such as these create warnings:

<meta name="keywords" content="web development,web hosting,consulting,internet consulting,domain name registration,westerly,internet,hosting" />
<br/>
<link rel="shortcut icon" href="CapsShieldIcon.ico" type="image/x-icon" />
<img src="HomePhotos/CentralPark1860x750.jpg" width="1860" height="750" alt="Central Park" title="Central Park"  class="img-responsive img-rounded center-block" />

Is this a bug or have things changed?

I just bumped into this today as well via a complete fluke.

I adjusted by source to comply with these requirements, as the best I can tell, they are correct.

I also found it was validating values. 0000-00-00 is not considered valid.

My issue is that there as not been a new release in over 2 years. I test against the June 30, 2020 release, and these errors are not flagged.

Ideally we need a new release. I don't see a vnu.jar file to download for the pre-release.

So all good, except for a new release!

@FrankPal It’s not a bug but instead it’s an intentional change that I made yesterday.

If you prefer to keep the document as-is rather than changing those tags to, e.g., <br> instead of <br/>, then you can use one of the checker’s message-filtering mechanisms to persistently filter out the “Self-closing tag syntax in text/html documents is widely discouraged” warning messages.

For example, you can use the Message Filtering button in the checker UI:

Awesome! This is a very valuable tool. I used it all the time in unit test to make sure my HTML is valid. All my sites validate 100% now with no errors or warnings. Nice stuff.

It is amazing how many (most) sites have bad HTML. UGH!
