I'm happy to announce the availability of the second beta release of the
new MediaWiki 1.19 release series.
Please try it out and let us know what you think. Don't run it on any
wikis that you really care about, unless you are both very brave and
very confident in your MediaWiki administration skills.
MediaWiki 1.19 is a large release that contains many new features and
bug fixes. This is a summary of the major changes of interest to users.
You can consult the RELEASE-NOTES-1.19 file for the full list of changes
in this version.
Five security issues were discovered.
It was discovered that the api had a cross-site request forgery (CSRF)
vulnerability in the block/unblock modules. It was possible for a user
account with the block privileges to block or unblock another user without
providing a token.
For more details, see https://bugzilla.wikimedia.org/show_bug.cgi?id=34212
It was discovered that the resource loader can leak certain kinds of private
data across domain origin boundaries, by providing the data as an executable
JavaScript file. In MediaWiki 1.18 and later, this includes the leaking of
CSRF
protection tokens. This allows compromise of the wiki's user accounts, say
by
changing the user's email address and then requesting a password reset.
For more details, see https://bugzilla.wikimedia.org/show_bug.cgi?id=34907
Jan Schejbal of Hatforce.com discovered a cross-site request forgery (CSRF)
vulnerability in Special:Upload. Modern browsers (since at least as early as
December 2010) are able to post file uploads without user interaction,
violating previous security assumptions within MediaWiki.
Depending on the wiki's configuration, this vulnerability could lead to
further
compromise, especially on private wikis where the set of allowed file types
is
broader than on public wikis. Note that CSRF allows compromise of a wiki
from
an external website even if the wiki is behind a firewall.
For more details, see https://bugzilla.wikimedia.org/show_bug.cgi?id=35317
George Argyros and Aggelos Kiayias reported that the method used to generate
password reset tokens is not sufficiently secure. Instead we use various
more
secure random number generators, depending on what is available on the
platform. Windows users are strongly advised to install either the openssl
extension or the mcrypt extension for PHP so that MediaWiki can take
advantage
of the cryptographic random number facility provided by Windows.
Any extension developers using mt_rand() to generate random numbers in
contexts
where security is required are encouraged to instead make use of the
MWCryptRand class introduced with this release.
For more details, see https://bugzilla.wikimedia.org/show_bug.cgi?id=35078
A long-standing bug in the wikitext parser (bug 22555) was discovered to
have
security implications. In the presence of the popular CharInsert extension,
it
leads to cross-site scripting (XSS). XSS may be possible with other
extensions
or perhaps even the MediaWiki core alone, although this is not confirmed at
this time. A denial-of-service attack (infinite loop) is also possible
regardless of configuration.
For more details, see https://bugzilla.wikimedia.org/show_bug.cgi?id=35315
*********************************************************************
What's new?
*********************************************************************
MediaWiki 1.19 brings the usual host of various bugfixes and new features.
Comprehensive list of what's new is in the release notes.
* Bumped MySQL version requirement to 5.0.2.
* Disable the partial HTML and MathML rendering options for Math,
and render as PNG by default.
* MathML mode was so incomplete most people thought it simply didn't work.
* New skins/common/*.css files usable by skins instead of having to copy
piles of
generic styles from MonoBook or Vector's css.
* The default user signature now contains a talk link in addition to the
user link.
* Searching blocked usernames in block log is now clearer.
* Better timezone recognition in user preferences.
* Extensions can now participate in the extraction of titles from URL paths.
* The command-line installer supports various RDBMSes better.
* The interwiki links table can now be accessed also when the interwiki
cache
is used (used in the API and the Interwiki extension).
Internationalization
- --------------------
* More gender support (for instance in user lists).
* Add languages: Canadian English.
* Language converter improved, e.g. it now works depending on the page
content language.
* Time and number-formatting magic words also now depend on the page
content language.
* Bidirectional support further improved after 1.18.

https://www.mediawiki.org/wiki/Release_notes/1.19
Co-inciding with these security releases, the MediaWiki source code
repository has
moved from SVN (at https://svn.wikimedia.org/viewvc/mediawiki/trunk/phase3)
to Git (https://gerrit.wikimedia.org/gitweb/mediawiki/core.git). So the
relevant
commits for these releases will not be appearing in our SVN repository. If
you use
SVN checkouts of MediaWiki for version control, you need to migrate these to
Git.
If you up are using tarballs, there should be no change in the process for
you.
Please note that any WMF-deployed extensions have also been migrated to Git
also, along with some other non WMF-maintained ones.
Please bear with us, some of the Git related links for this release may not
work instantly,
but should later on.
To do a simple Git clone, the command is:
git clone https://gerrit.wikimedia.org/r/p/mediawiki/core.git
More information is available at https://www.mediawiki.org/wiki/Git

Hi everyone,
I recently set up a MediaWiki (http://server.bluewatersys.com/w90n740/)
and I need to extra the content from it and convert it into LaTeX
syntax for printed documentation. I have googled for a suitable OSS
solution but nothing was apparent.
I would prefer a script written in Python, but any recommendations
would be very welcome.
Do you know of anything suitable?
Kind Regards,
Hugo Vincent,
Bluewater Systems.
I'm currently investigating alternative bug tracker and project management
software for MediaWiki. To do that I'll be installing some different
software on the Labs and importing existing bugs for evaluation by the
development team and users. The following software is planned for test:
- JIRA <http://www.atlassian.com/software/jira/overview> + Greenhopper +
Bonfire
- YouTrack <http://www.jetbrains.com/youtrack/>
- The Bug Genie <http://www.thebuggenie.com/index.php>
- Redmine <http://www.redmine.org/>
- ChiliProject <https://www.chiliproject.org/>
If you have any suggestions for this list I'd be glad to hear it.
Of course, this goes back to the original request. To do this I need a dump
of the current Bugzilla install. Is it possible for me to get this and
under what conditions? Thank you.

Dear all,
My apologies up front for the long e-mail that follows. In this e-mail you
will find a comprehensive status overview of the recent WebFonts deployment.
On Monday December 12 at 18:00 UTC we deployed the extension WebFonts[1] to
40 wikis in 11 Indic languages and Wikimedia Incubator -- all wikis in
Assamese, Bengali, Gujarati, Hindi, Kannada, Marathi, Nepali, Oriya,
(Eastern) Punjabi, Sankrit and Telugu have WebFonts now. WebFonts was not
deployed on Malayalam and Tamil projects. The reason for this was that
community members had requested us not to. We are confident that in time,
the communities will request that WebFonts is enabled on their projects.
WebFonts aims to resolve the issue that users see incomplete web pages,
because the fonts to properly render the page is not present in the local
system by downloading the font through the browser.
One of our great challenges developing this functionality is the multitude
of scripts and the low availability of freely licensed fonts that may be
modified and redistributed.
Over the past few months we have tried to build out a collection of fonts
in the extension mainly for Indic languages, and we have performed many
tests. We have solicited community involvement through messaging in village
pumps, e-mails on mailing lists, blog posts on personal blogs as well as on
the Wikimedia Foundation blog, at developer events, through personal
e-mails and through our bug tracker, and gotten some feedback, although
unfortunately not for all the languages we would like to have gotten it
for. We will of course continue our efforts in this area. Next to the
community involvement, we have had a two day session with the Red Hat
Localisation team in Pune, India.
Since the deployment, we have been criticised for not communicating enough
-- or not through the right channels, not with the right people, not in
time, or too soon, or not with the right messages. I'm not really sure how
to respond to that, except for uttering a general "mea culpa, mea maxima
culpa". We are working really hard in continuously improving the work that
we do, and the way that we do it. We make mistakes, we are human after all,
and when we become aware of our mistakes, we will do everything in our
power to make it better.
With our team we support the mission of the Wikimedia Foundation to
"imagine a world in which every single human being can freely share in the
sum of all knowledge." I care about that -- a lot. We all care, and I am
pretty certain that we're not ignorant, dismissive or incapable. I
acknowledge that we as the Localisation team are a relatively new entity
within the MediaWiki development community and within the Wikimedia
Foundation, with a very wide scope, and that we are dealing with a lot of
technical details on which we are simply not able to assess the final
quality; there are after all 7.500 languages in this world of over 7
billion people that we theoretically all cover, some 350 of those languages
are supported in MediaWiki, and 280 within Wikimedia.
I accept that we cannot keep everybody happy -- doesn't keep us from
trying, though. I want to try and work with as many people as possible in a
constructive way. With these numbers, that's not always easy to coordinate.
To channel the input on languages, we have set up "Language Support
Teams"[2]. We do not yet have a language support team for every language.
Please sign up if you care about the technical facilitation of your
language in the Wikimedia movement. Let's use the mediawiki-i18n mailing
list[3] to have constructive discussions about language support. Let's use
the #mediawiki-i18n IRC channel[4] on Freenode to have real-time
discussions. Let's use bugzilla.wikimedia.org to report bugs[5]. Link [5]
explains the bug reporting procedure. If you already know how, report
issues quickly using this link: http://ur1.ca/6ov9a .
Since the deployment, we have been made aware of about 17 issues. Some very
serious in nature, others not requiring immediate attention. Yesterday an
issue with web fonts not loading in Firefox was resolved in the
infrastructure. Today around 15:30 UTC, we have deployed fixes for an
additional hand full of issues[6]: functionality disabled in IE6, IE8 on
Windows XP, selection buttons not working properly in IE7 and hiding the
Samyak fonts in the font selector. During our current sprint, we are
working on a framework for multi-lingual and localised user documentation
as well as feature based feedback functionality for WebFonts, Narayam and
Translate. In the future we will also explore what is known as "dark
launch" by some, a kind of hidden live deployment of a feature, only usable
be for example manipulating a URL. This would allow us to deploy a feature
in a live environment, without having the "full deployment" impact.
Thanks for reading through this. I am looking forward to working with you!
Please read on for details on all the issues that were reported on WebFonts
recently.
Cheers!

Open issues
=======================================
https://bugzilla.wikimedia.org/33004 -- Old cached pages do not have web
fonts enabled
Priority: HIGH
--------------------------------------------------------------------------------------
Wikimedia is able to serve this many pages with relative few servers
because of very aggressive caching strategies, especially for anonymous
users. WebFonts requires the addition of JavaScript for anonymous users,
which is not being done for pages that are in the squid cache at the moment
WebFonts was enabled. All squid cache objects for wikis on which WebFonts
was deployed need to be purged. An internal RT ticket created for the
Wikimedia Operations team to get anonymous squid caches purged. This may
take up to a week or longer to be resolved.
https://bugzilla.wikimedia.org/33018 -- Firefox 5 on Windows XP has script
time-outs
Priority: MEDIUM
--------------------------------------------------------------------------------------
The Localisation team has tested this report, and was not yet able to
confirm the observation. The reason for using a non-recent version of
Firefox for the report was the alleged lower memory usage. Brion noted that
Mozilla has been actively working on lowering memory usage over the last
year, so the reporter may be better off with the current versions than the
old ones.
https://bugzilla.wikimedia.org/33110 -- Google Crome on Windows XP dispays
gibberish
Priority: LOW
--------------------------------------------------------------------------------------
Observed very rarely on a page on Wikimedia Incubator, and we have not been
able to reproduce this observation, let alone reproduce it reliably. A
screenshot is present in the bug report. Except for reporting upstream, no
action is being taken on this issue at this point in time.
https://bugzilla.wikimedia.org/33054 -- Hinting issues in Lohit fonts
Priority: MEDIUM
--------------------------------------------------------------------------------------
Confirmed in Windows XP. We can do something to the font by adding hinting,
but this is a lot of work if it needs to be done manually. The stem of the
Lohit glyphs could do with more width and darkness. This may not be
desirable for platforms (Linux) which render it perfectly, because it
already has hinting and anti-aliasing on an operating system level. Same
goes got Windows 7.
https://bugzilla.wikimedia.org/33100 -- Page crashes on Webkit browsers
with WebFonts enabled.
Priority: MEDIUM (could be HIGH if we find many occurances)
--------------------------------------------------------------------------------------
A page in Nepali Wikipedia makes a tab on Mac OS X 10.7.2 with Google Crome
crash. This behaviour was also reported for Mac OS X 10.7.2 (11C74) with
Safari 5.1.1 (7534.51.22, r102522) [This is a webkit nightly build] by
thedj. This is most probably related to the WebFonts code, because if, as a
logged in user, web fonts is disabled in preferences, the page does not
crash Chrome.
Developer Derk-Jan Hartman was asked to report this bug in the WebKit.
Please make us aware of any additional pages that would cause this
behaviour in any wiki.
https://bugzilla.wikimedia.org/33102 -- OSX 10.7.2/Opera 11.60 has no
fallback for Latin characters
Priority: MEDIUM
--------------------------------------------------------------------------------------
This is a bug that needs to be reported upstream. No technical measures
have been taken so far to mitigate this issue. One of the Localisation team
members has been in contact with a high level executive of Opera, and will
contact that person again. We're going to wait for a few days for an
outcome -- if there is no expectation of a relatively quick fix, we might
disable WebFonts for Opera completely. Opera unfortunately does not have a
public bug tracker.
https://bugzilla.wikimedia.org/33027 -- Narayam and WebFonts both loading
slows down page
Priority: MEDIUM
--------------------------------------------------------------------------------------
The reporter claims that the functionality is quicker on
translatewiki.netthan it is in Wikimedia wikis. A commenter states
that more functionality
usually means more code, means more data that needs to be transferred, and
without changing bandwidth, that causes longer load times.
This currently isn't our highest priority, but eventually we will look into
this a little deeper. We're inviting volunteers to do some of the data
gathering and analysis for us. What is needed in our opinion is insight in
the data volume added by WebFonts, as well as an assessment of the code
quality with regards to size optimisation. All referenced properly, of
course :). There are alternate EOT conversion tools that have a good
compression ratio. Needs to be explored, but EOT is not required for modern
browsers since they started using WOFF fonts which are compressed OpenType
fonts.
https://bugzilla.wikimedia.org/33085 -- Integration of updated Lohit-Tamil
Font
Priority: MEDIUM
--------------------------------------------------------------------------------------
Request to update WebFonts with a font that is updated upstream. This is
something the Localisation team checks regularly. Will probably be closed
this week, pending issues the have a higher priority.
https://bugzilla.wikimedia.org/32942 -- Provide help page and bug report
link for WebFonts
Priority: HIGH
--------------------------------------------------------------------------------------
More recently developed tools by the Wikimedia Foundation have often
included feedback mechanisms. The Localisation team plans on implementing
these for the functionality of the WebFonts, Narayam and Translate
extension. Besides that, we also want to provide multi-lingual and
localised documentation. This needs some thinking and some work to provide
in a structured and navigable way. We'll keep you posted. It will most
probably involve translatable *user* documentation on MediaWiki.org and
hopefully it is possible to have one feedback location per feature across
the multiple Wikimedia wikis -- this is something we're going to contact
the ArticleFeedback and MoodBar teams for.
=======================================
Closed issues
=======================================
https://bugzilla.wikimedia.org/33025 -- When changing to a non-default web
font, the content does not
--------------------------------------------------------------------------------------
This issue was a side effect of a feature to allow multiple web fonts to be
used using the "lang" attribute. It was resolved in
https://www.mediawiki.org/wiki/Special:Code/MediaWiki/105980 and has been
deployed.
https://bugzilla.wikimedia.org/33034 -- Web fonts not loading in Firefox
--------------------------------------------------------------------------------------
Duplicate reports were 33038 and 33044. This issue originated from
http://www.w3.org/TR/css3-fonts/#same-origin-restriction. Almost all
browsers except for Firefox ignore that specification. A fix was designed
and deployed: https://www.mediawiki.org/wiki/Special:Code/MediaWiki/106092,
https://gerrit.wikimedia.org/r/1501. Thanks to Roan, Brion and Ryan for
their help.
https://bugzilla.wikimedia.org/32775 -- Gibberish in Internet Explorer 8 on
Windows XP
--------------------------------------------------------------------------------------
This is an unexplained phenomenon only observed in Internet Explorer on
Windows XP. It is also hard to reproduce. One of the developers was able to
make something somewhat reproducible on a clean, fully patched installation
of Windows XP with Internet Explorer 8. See bug report for details.
Based on these observations we think it is a bad idea to keep supporting
WebFonts in Internet Explorer 8 on Windows XP and we have disabled it in
https://www.mediawiki.org/wiki/Special:Code/MediaWiki/106172. This fix has
been deployed.
https://bugzilla.wikimedia.org/33096 -- Internet Explorer 6 does not have
font fallback
--------------------------------------------------------------------------------------
IE6 not having font fallback causes Latin characters to display as squares
when a web font is loaded that does not contain glyphs for the Latin
script. A screenshot is available at
http://media.crossbrowsertesting.com/users/34057/screenshots/window/z669002….
Based on this observation, we think it is a bad idea to keep supporting
WebFonts in Internet Explorer 6 and we have disabled it in
https://www.mediawiki.org/wiki/Special:Code/MediaWiki/106172. This fix has
been deployed.
https://bugzilla.wikimedia.org/33024 -- WebFonts menu buttons not working
in IE7
--------------------------------------------------------------------------------------
This was caused by the JavaScript $( '<input type="radio" />' ) . attr(
"name" ,"font"); not working in IE6 and IE7. Updating name attributes once
they have been created is not possible. We think there may be more
occurances of this in our code (one occurance in jQuery has already been
identified: resources/jquery/jquery.validate.js:59). A fix was made in
https://www.mediawiki.org/wiki/Special:Code/MediaWiki/106175. This fix has
been deployed.
https://bugzilla.wikimedia.org/33040 -- Overlap in Samyak font for Hindi
and Sanskrit
--------------------------------------------------------------------------------------
This issue occurs in Windows XP and Windows 7 (possibly also in Windows
Vista) when using Google Chrome. It is not observed when using Chrome with
Mac OS X 10.7.2 or several Linux distributions (Debian and Fedora). Samyak
Devanagari is available as a non-default web font in Hindi, Marathi, and
Sanskrit. Samyak Gujarati is available for Gujarati as a non-default font.
This font needs to be corrected. The maintainers will be notified of the
observed issues, and mean while, the fonts will be removed from the
WebFonts selection list (but can still be used using the font-family
property. A fix was made in
https://www.mediawiki.org/wiki/Special:Code/MediaWiki/106179. This fix has
been deployed.
https://bugzilla.wikimedia.org/33039 -- Overlap in Madan font for Nepali
--------------------------------------------------------------------------------------
This report was invalid. The reporter was not aware of the correct glyph
for the Nepali script.
Comments on this bug report resulted in two odd observations (Crome crash,
Opera font fallback), that have been split off into separate bug reports:
https://bugzilla.wikimedia.org/33100 and
https://bugzilla.wikimedia.org/33102.
https://bugzilla.wikimedia.org/33095 -- WebFonts menu can expand off the
screen
--------------------------------------------------------------------------------------
If the translations for "Select font" and "Login / Register" are really
short, like in http://mr.wiktionary.org, expanding the WebFonts menu for
anonymous users will display a menu that is partially off the screen. It
was resolved in http://www.mediawiki.org/wiki/Special:Code/MediaWiki/106186,
http://www.mediawiki.org/wiki/Special:Code/MediaWiki/106197,
http://www.mediawiki.org/wiki/Special:Code/MediaWiki/106201,
http://www.mediawiki.org/wiki/Special:Code/MediaWiki/106202. These
revisions also depend on a few small UI changes of both WebFonts and
Narayam, and will be deployed on December 19, 2011.
<no bugzilla report> -- WebFonts menu expands under the control for
customised input method in IE6 on transliteration
--------------------------------------------------------------------------------------
There are issues with the z index in IE6. Because of
https://www.mediawiki.org/wiki/Special:Code/MediaWiki/106172, WebFonts is
no longer available in IE6, so this issue is obsolete. Observing that the
Hindi projects Wikipedia and Wiktionary are using an custom input methods
tool, we would like to invite them to test Narayam which contains many
input methods in a MediaWiki extension. We are very open to having the
Hindi input method InScript tested and add a transliteration input method
with some community representatives, as we have done with other Indic
languages. We hope this will eventually lead to Narayam being adopted by
the Hindi community, and the custom input method being abandoned.
Hi, it's been almost 4 years since we came with the idea of
implementing an OAuth to mediawiki. I think it's time to start.
Question now is if it should be a part of core or extension for
mediawiki. I myself would rather make it as extension, since there is
probably no use for most of installations, except for large wikis.
Quote:
OAuth provides a standard protocol to negotiate secure access tokens
and to provide third-party tools (web or client) with granular access
to private resources. This protocol does not reveal usernames or
passwords to the third-party tool. Offering OAuth based authorization
on Mediawiki wiki's will increase the reusability of its data and spur
the creation of an ecosystem of app's around Mediawiki.
Is there anyone who is willing to help with this? If there is no one
interested in this, or no comments, I would start a new extension
called OAuth, which only purpose would be to enable this feature in
mediawiki.
Hi all. I have a bold proposal (read: evil plan).
To put it briefly: I want to remove the assumption that MediaWiki pages contain
always wikitext. Instead, I propose a pluggable handler system for different
types of content, similar to what we have for file uploads. So, I propose to
associate a "content model" identifier with each page, and have handlers for
each model that provide serialization, rendering, an editor, etc.
The background is that the Wikidata project needs a way to store structured data
(JSON) on wiki pages instead of wikitext. Having a pluggable system would solve
that problem along with several others, like doing away with the special cases
for JS/CSS, the ability to maintain categories etc separate from body text,
manage Gadgets sanely on a wiki page, or several other things (see the link below).
I have described my plans in more detail on meta:
http://meta.wikimedia.org/wiki/Wikidata/Notes/ContentHandler
A very rough prototype is in a dev branch here:
http://svn.wikimedia.org/svnroot/mediawiki/branches/Wikidata/phase3/
Please let me know what you think (here on the list, preferably, not on the talk
page there, at least for now).
Note that we *definitely* need this ability for Wikidata. We could do it
differently, but I think this would be the cleanest solution, and would have a
lot of mid- and long term benefits, even if it's a short term pain. I'm
presenting my plan here to find out if I'm on the right track, and whether it is
feasible to put this on the road map for 1.20. It would be my (and the Wikidata
team's) priority to implement this and see it through before Wikimania. I'm
convinced we have the manpower to get it done.
Cheers,
Daniel
I invite you to the yearly Berlin hackathon. It's 1-3 June and
registration is now open. If you need financial assistance or help with
hotel/hostel, just mention it in the registration form.
https://wmberlin.eventbrite.com/
This is the premier event for the MediaWiki and Wikimedia technical
community. We'll be hacking, designing, and socialising, primarily
talking about Gadgets, the switch to Lua, Wikidata, and Wikimedia Labs.
Our goals for the event are to bring 100-150 people together, with
lots of people who have not attended such events before. User
scripts, gadgets, API use, Toolserver, Wikimedia Labs, mobile,
structured data, templates -- if you are into any of these things, we
want you to come!
Details: https://www.mediawiki.org/wiki/Berlin_Hackathon_2012
Thanks to Wikimedia Germany for hosting and coordinating this event.
(Venue still to be determined.)

Hi !
I thank you all everybody for your nice job, mediawiki is a great platform.
However, as you may know, we are some people to develop , contribute to
some extensions, and every time I migrate my wiki setup to a new
version, that looks like a nightmare !!! (mostly for the last 1.18.1).
I have either to upgrade extensions or dive into php code to make it
running with the new mediawiki release.
But this time, with 1.18.1 I am worried, because I do not have an in
deep knowledge of the mediawiki process.
So, the next time, a release is delivered, please provide with it a
migration guide for extensions !!!!! This will permit every developer to
maintain in a fast and efficient way, most extensions !! And since we
are all very good developers, I am pretty sure some people will be able
to provide a helpful migrating utility (when only function name changes
apply) ....
Today, I am not able to participate or migrate the CKeditor to the
1.18.1 Release .
Regards .

In the last few days I've updated the Math extension's experimental MathJax
support to where it can actually be enabled by individual users. If all
goes well with review I'd love to get this deployed soon so the math-heads
can turn it on and check for lingering incompatibilities...
MathJax [http://www.mathjax.org/] is a client-side JavaScript library for
parsing TeX or MathML code and rendering it in just about any modern
browser -- it even works back to IE 6! -- using webfonts and HTML/CSS,
MathML, or SVG as available.
Here's a sample page on a test wiki, copied from en.wikipedia:
http://leuksman.com/mw/index.php/Alpha_compositing
This update to the extension builds on Nageh's work setting up an earlier
version of MathJax as a user script, plus some help from the MathJax devs
on their mailing list. Thanks guys!
Big advantages of this over our current server-side math rendering:
* font size & baseline match up with surrounding text for inline equations!
* subpixel antialiasing or high-dpi displays allow math to render more
sharply at default size
* scalable -- you can zoom in your browser and things stay sharp
* printable -- printed output also stays sharp (some browsers have font
issues with some modes; to be experimented with)
* in-browser zoom & copy-paste helpers
And of course:
* a strong open-source community maintaining it, who are happy to help us
with integration and any needed fixes
* it's not ocaml ;)
The additions to Math extension add a third 'MathJax' rendering mode which
users can opt in to at Special:Preferences. This replaces the older HTML
and MathML rendering modes that we already disabled in 1.19.
In the future when we've worked out the kinks, we can turn that into the
default, and continue to use it as a fallback renderer for non-JavaScript
browsers. (A nicer math edit/preview tool would be awesome too, especially
for confirming that things work in both renderers in the future!)
