3.0 upgrade guide doesn't mention breaking change to TABLE/TBODY under manipulation

[rmacfadyen]

per: JQuery 3.1.1 vs 2.2.4 change in behavior appending rows to a table jquery/jquery#3976

The following code:

$('<TABLE />').append('<TR><TD>1</TD></TR>').appendTo('BODY');
results in slightly different DOM structures.

Under 2.2.4 you get <TABLE><TBODY><TR>...

Under 3.1.1 you get <TABLE><TR>...

(one has a TBODY and one does not)

This causes problems if you later have selectors like #id TBODY TR (to get all the body rows, and no header rows).

Apparently the fix for jquery/jquery#1835 in 3.0.0 is why.

Not sure what the upgrade guide should say though (I really don't understand the scope or the reason why #1835 resulted in this change). It did affect my upgrade of some code (unexpectedly)... and I had reviewed the upgrade guide specifically looking for breaking changes before upgrading.

Maybe something like "document fragment of a single TABLE element will no longer have a TBODY created automatically"?
