Various legacy MathML features have been deprecated

Published: | Categories: Miscellaneous

Description

As with Firefox 70, the MathML implementation has been updated with Firefox 71 for the current MathML Core (future MathML 4) spec. The following features are now deprecated, disabled in Firefox Nightly and will be removed in the future:

  • The align attribute on the <munderover>, <munder> and <mover> elements
  • The denomalign and numalign attributes on the <mfrac> element
  • The radical value for the <menclose> element’s notation attribute. Use the <msqrt> element instead
  • XLink attributes on MathML elements: xlink:actuate, xlink:href, xlink:show and xlink:type. The href attribute can be used instead of xlink:href
