10.3.2 - Oops, "Javascript".

Tiny tiny release, just to fix the website incorrectly not listing Javascript
in the list of languages you could choose for a custom build. NPM and CDN
build should not have been affected so 10.3.1 is effectively the same as
10.3.2 for those builds.

If you made a custom build from the website with 10.3 or 10.3.1 you may
want to check and make sure it includes Javascript, and if not, build it again.

10.3.1 hotfix

Prior version let some look-behind regex sneak in, which does not work
yet on Safari. This release removes those incompatible regexes.

Fixes:

• fix(Safari) Remove currently unsupported look-behind regex (fix) Josh Goebel

10.3.0

Lots of large and small improvements to grammars including a major rewrite of our LaTeX grammar. See CHANGES.md for full list. Thanks for the interest from StackOverflow and Octoberfest!

• The useBR option deprecated and will be removed in v11.0.

Thanks to everyone who contributed to this release:

• Chris Krycho
