Pale Moon 33.1.0 changelog:

New features

Implemented support for single-use meta tag. This implementation allows use of it without specifying a second meta tag to actually load the linked document which was originally intended for this tag (to hint to a browser it should pre-load the document for fast painting).
Implemented CSP v3 keywords script-src-elem, script-src-attr, style-src-elem and style-src-attr.
Enabled the use of html5's by default. While this is not yet a complete implementation, use of it in the wild dictated we enable this early. The implementation should functionally suffice for usage seen so far.
Added support for Emoji 15.1.
Implemented webkitURL legacy window alias for URL for web compatibility.
Implemented CSS shorthands margin-block, margin-inline, padding-block and padding-inline.
Added support for querying CPU capabilities (SSE2/AVX/AVX2) to the Navigator interface. For privacy reasons this is not exposed to the web, but can be used by extensions.
