Version 9.0.0
The new major version brings a reworked styling system. Highlight.js now defines a limited set of highlightable classes giving a consistent result across all the styles and languages. You can read a more detailed explanation and background in the [tracking issue][#348] that started this long process back in May.
This change is backwards incompatible for those who uses highlight.js with a custom stylesheet. The [new style guide][sg] explains how to write styles in this new world.
Bundled themes have also suffered a significant amount of improvements and may look different in places, but all the things now consistent and make more sense. Among others, the Default style has got a refresh and will probably be tweaked some more in next releases. Please do give your feedback in our [issue tracker][issues].

tag now allows any language, not just JavaScript.We've got the new [demo page][]! The obvious new feature is the new look, but apart from that it's got smarter: by presenting languages in groups it avoids running 10000 highlighting attempts after first load which was slowing it down and giving bad overall impression. It is now also being generated from test code snippets so the authors of new languages don't have to update both tests and the demo page with the same thing.
Other notable changes:

.New languages:
We streamlined our tool chain, it is now based entirely on node.js instead of being a mix of node.js, Python and Java. The build script options and arguments remained the same, and we've noted all the changes in the [documentation][b]. Apart from reducing complexity, the new build script is also faster from not having to start Java machine repeatedly. The credits for the work go to [Jeremy Hull][].
Some notable fixes:
throw
keyword is no longer detected as a method name in Java.New languages in this release:
We've finally got [real tests][test] and [continuous testing on Travis][ci] thanks to [Jeremy Hull][] and [Chris Eidhof][]. The tests designed to cover everything: language detection, correct parsing of individual language features and various special cases. This is a very important change that gives us confidence in extending language definitions and refactoring library core.
We're going to redesign the old [demo/test suite][demo] into an interactive demo web app. If you're confident front-end developer or designer and want to help us with it, drop a comment into [the issue][#542] on GitHub.
As usually there's a handful of new languages in this release:

listLanguages()
][ll] method in the API.lang-
prefix for language names in HTML classes supported
alongside language-
. Thanks to [Jeff Escalante][].This new major release is quite a big overhaul bringing both new features and some backwards incompatible changes. However, chances are that the majority of users won't be affected by the latter: the basic scenario described in the README is left intact.
Here's what did change in an incompatible way:
We're now prefixing all classes located in [CSS classes reference][cr] with
hljs-
, by default, because some class names would collide with other
people's stylesheets. If you were using an older version, you might still want
the previous behavior, but still want to upgrade. To suppress this new
behavior, you would initialize like so:
<script type="text/javascript">
hljs.configure({classPrefix: ''});
hljs.initHighlightingOnLoad();
</script>
tabReplace
and useBR
that were used in different places are also unified
into the global options object and are to be set using configure(options)
.
This function is documented in our [API docs][]. Also note that these
parameters are gone from highlightBlock
and fixMarkup
which are now also
rely on configure
.
We removed public-facing (though undocumented) object hljs.LANGUAGES
which
was used to register languages with the library in favor of two new methods:
registerLanguage
and getLanguage
. Both are documented in our [API docs][].
Result returned from highlight
and highlightAuto
no longer contains two
separate attributes contributing to relevance score, relevance
and
keyword_count
. They are now unified in relevance
.
Another technically compatible change that nonetheless might need attention:
require('highlight.js')
works as before. This is contributed by [Dmitry Smolin][].New features:
Languages now can be recognized by multiple names like "js" for JavaScript or "html" for, well, HTML (which earlier insisted on calling it "xml"). These aliases can be specified in the class attribute of the code container in your HTML as well as in various API calls. For now there are only a few very common aliases but we'll expand it in the future. All of them are listed in the [class reference][cr].
Language detection can now be restricted to a subset of languages relevant in
a given context — a web page or even a single highlighting call. This is
especially useful for node.js build that includes all the known languages.
Another example is a StackOverflow-style site where users specify languages
as tags rather than in the markdown-formatted code snippets. This is
documented in the [API reference][] (see methods highlightAuto
and
configure
).
Language definition syntax streamlined with [variants][] and [beginKeywords][].

Miscellaneous improvements:
=>
prompts in Clojure.A catch-up release dealing with some of the accumulated contributions. This one is probably will be the last before the 8.0 which will be slightly backwards incompatible regarding some advanced use-cases.
One outstanding change in this version is the addition of 6 languages to the [hosted script][d]: Markdown, ObjectiveC, CoffeeScript, Apache, Nginx and Makefile. It now weighs about 6K more but we're going to keep it under 30K.

.The latest long period of almost complete inactivity in the project coincided with growing interest to it led to a decision that now seems completely obvious: we need more core developers.
So without further ado let me welcome to the core team two long-time contributors: [Jeremy Hull][] and [Oleg Efimov][].
Hope now we'll be able to work through stuff faster!
P.S. The historical commit is [here][1] for the record.
This long overdue version is a snapshot of the current source tree with all the changes that happened during the past year. Sorry for taking so long!
Along with the changes in code highlight.js has finally got its new home at http://highlightjs.org/, moving from its cradle on Software Maniacs which it outgrew a long time ago. Be sure to report any bugs about the site to mailto:info@highlightjs.org.
On to what's new…
New languages:
New style themes:
Other notable changes:
Since this version highlight.js no longer works in IE version 8 and older. It's made it possible to reduce the library size and dramatically improve code readability and made it easier to maintain. Time to go forward!
New languages: AppleScript (by [Nathan Grigg][ng] and [Dr. Drang][dd]) and Brainfuck (by [Evgeny Stepanischev][bolk]).

)Also Oleg Efimov did a great job of moving all the docs for language and style developers and contributors from the old wiki under the source code in the "docs" directory. Now these docs are nicely presented at http://highlightjs.readthedocs.org/.
A regular bug-fix release without any significant new features. Enjoy!
A Summer crop:
The reason for the new major version update is a global change of keyword syntax which resulted in the library getting smaller once again. For example, the hosted build is 2K less than at the previous version while supporting two new languages.
Notable changes:
The library now works not only in a browser but also with [node.js][]. It is
installable with npm install highlight.js
. [API][] docs are available on our
wiki.
The new unique feature (apparently) among syntax highlighters is highlighting HTTP headers and an arbitrary language in the request body. The most useful languages here are XML and JSON both of which highlight.js does support. Here's [the detailed post][p] about the feature.
Two new style themes: a dark "south" [Pojoaque][] by Jason Tate and an emulation ofXCode IDE by [Angel Olloqui][ao].
Three new languages: D by [Aleksandar Ružičić][ar], R by [Joe Cheng][jc] and GLSL by [Sergey Tikhomirov][st].
Nginx syntax has become a million times smaller and more universal thanks to remaking it in a more generic manner that doesn't require listing all the directives in the known universe.
Function titles are now highlighted in PHP.
Haskell and VHDL were significantly reworked to be more rich and correct by their respective maintainers [Jeremy Hull][sr] and [Igor Kalnitsky][ik].
And last but not least, many bugs have been fixed around correctness and language detection.
Overall highlight.js currently supports 51 languages and 20 style themes.
A lot of things happened in highlight.js since the last version! We've got nine new contributors, the discussion group came alive, and the main branch on GitHub now counts more than 350 followers. Here are most significant results coming from all this activity:
5 (five!) new languages: Rust, ActionScript, CoffeeScript, MatLab and experimental support for markdown. Thanks go to [Andrey Vlasovskikh][av], [Alexander Myadzel][am], [Dmytrii Nagirniak][dn], [Oleg Efimov][oe], [Denis Bardadym][db] and [John Crepezzi][jc].
2 new style themes: Monokai by [Luigi Maselli][lm] and stylistic imitation of another well-known highlighter Google Code Prettify by [Aahan Krish][ak].
A vast number of [correctness fixes and code refactorings][log], mostly made by [Oleg Efimov][oe] and [Evgeny Stepanischev][es].
[Jeremy Hull][jh] has implemented my dream feature — a port of [Solarized][] style theme famous for being based on the intricate color theory to achieve correct contrast and color perception. It is now available for highlight.js in both variants — light and dark.
This version also adds a new original style Arta. Its author pumbur maintains a [heavily modified fork of highlight.js][pb] on GitHub.
New major version of the highlighter has been built on a significantly refactored syntax. Due to this it's even smaller than the previous one while supporting more languages!
New languages are:
Also this version is marginally faster and fixes a number of small long-standing bugs.
Developer overview of the new language syntax is available in a [blog post about recent beta release][beta].
P.S. New version is not yet available on a Yandex CDN, so for now you have to download [your own copy][d].
