If you’re using <!doctype HTML>, you’re writing HTML5.

According to the HTML5 specs at https://html.spec.whatwg.org/ 
<https://html.spec.whatwg.org/>, (dated September 28, 2022) Section 13.1.2.1, 
Start tags:

        • After the attributes, or after the tag name if there are no 
attributes, there may be one or more ASCII whitespace. (Some attributes are 
required to be followed by a space. See the attributes section below.)
        • Then, if the element is one of the void elements, or if the element 
is a foreign element, then there may be a single U+002F SOLIDUS character (/). 
This character has no effect on void elements, but on foreign elements it marks 
the start tag as self-closing.
        • Finally, start tags must be closed by a U+003E GREATER-THAN SIGN 
character (>).

The enumeration of void elements in section 13.1.2 lists br as a void element.

Therefore, at least in the eyes of WHATWG, the slash is optional in a <br> tag.
