Attention
Version 3 is now the current version of MathJax. This document is for version 2.
What’s New in MathJax v2.2¶
MathJax v2.2 includes a number of new features, as well a more than 40 important bug fixes.
Features:¶
- Localization of MathJax user interface. (German and French translations currently available in addition to English.)
- Commutative diagrams via the
AMScd
extension. - New Safe-mode extension that allows you to restrict potentially dangerous features of MathJax when it is used in a shared environment (e.g., href to javascript, styles and classes, etc.)
- Improve MathML rendering for
mfenced
andmlabeldtr
elements in browsers that don’t support them well. - Experimental Content MathML support.
TeX input:¶
- Avoid potential infinite loops in
\mathchoice
constructs. (Issue #373) - Add error message when an evironment closes with unbalanced braces. (Issue #454)
- Allow spaces in the RGB, rgb, and greyscale color specifications. (Issue #446)
- Process
\$
in\text
arguements. (ssue #349) - Preserve spaces within
\verb
arguments. (Issue #381) - Make
\smallfrown
and\smallsmile
come from the variant font so they have the correct size. (Issue #436) - Make the input TeX jax generate mrow plus mo elements rather than mfenced elements (for better compatibility with native MathML implementations).
- Make
\big
and its relatives use script or scriptscript fonts (although size is still absolute, as it is in TeX) so that it balances the text weight in scripts. (Issue #350) - Convert true and false attributes to booleans in
\mmlToken
. (Issue #451)
AsciiMath:¶
- Rename AsciiMath config option from
decimal
todecimalsign
. (Issue #384)
Fonts:¶
- Add Greek Delta to SVG fonts. (Issue #347)
- Fix monospace space character to be the same width as the other monospace characters. (Issue #380)
- Better handling of unknown or invalid values for mathvariant or values not supported by generic fonts.
MathML:¶
- Handle empty child nodes better.
- Improved MathML rendering for
mfenced
andmlabeldtr
elements. - Ignore
linebreak
attribute onmspace
when dimensional attributes are set. (Issue #388) - Implement
rowspacing
/columnspacing
formtable
in native MathML output in Firefox using cell padding.
HTML-CSS/SVG output¶
- Allow
\color
to override link color in SVG output. (Issue #427) - Add min-width to displayed equations with labels so that they cause their containers to have non-zero width (like when they are in a table cell or an absolutlye positioned element). (Issue #428)
- Fix a processing error with elements that contain hyperlinks. (Issue #364)
- Try to isolate MathJax from CSS transitions. (Issue #449)
- Go back to using em’s (rounded to nearest pixel) for Chrome. Rounding makes the placement work more reliably, while still being in relative units. (Issue #443)
- Prevent error when math contains characters outside of the MathJax fonts. (Issue #441)
- Make final math size be in relative units so that it prints even if print media has a different font size. (Issue #386)
- Don’t scale line thickness for
menclose
elements (so lines won’t disapear in scripts). (Issue #414) - Fix
fontdata.js
to allow it to be included in combined configuration files. (Issue #413) - Makes math-based tooltips be spaced properly when rendered. (Issue #412)
- Fix Math Processing Error when
&ApplyFunction
; is used without preceeding content. (Issue #410) - Fix a problem using an empty table as a super- or subscript. (Issue #392)
- Handle the case where selection in maction is invalid or out of range. (Issue #365)
- Add a pixel extra around the SVG output to accommodate antialiasing pixels. (Issue #383)
- Fix Math Processing Error for
msubsup
/msub
/msup
elements. - Limit the number of repetition to build stretchy chars in HTML-CSS. (Issue #366)
- Fix Math Processing Error in
mmultiscripts
/menclose
. (Issue 362)
Interface:¶
- Make zoom work properly with expressions that have full width (e.g., tagged equations).
- Handle zooming when it is inside a scrollable element when it is not the main body element. (Issue #435)
- Update math processing errors to include original format and actual error message in the “Show Math As” menu. (Issue #450)
- Add a Help dialog box (rather than link to mathjax.org).
- Remove the v1.0 configuration warning. (Issue #445)
- Trap errors while saving cookies (and go on silently). (Issue #374)
- Fix typo in IE warning message. (Issue #397)
- Use UA string sniffing for identifying Firefox and handle detecting mobile versions better.
- Make MathML source show non-BMP characters properly. (Issue #361)
- Make tool tips appear above zoom boxes. (Issue #351)
Miscellaneous:¶
- Allow preview for preprocessors to be just a plain string (rather
than requiring
[string]
). - Remap back-tick to back-quote. (Issue #402)
- Handle script tags in
HTML.Element()
so they work in IE. (Issue #342) - Add the
MathJax_Preview
class to theignoreClass
list so thattex2jax
andasciimath2jax
won’t process previews accidentally. (Issue #378) - Fix processing errors with various table and menclose attributes. (Issue #367)
- Use
hasOwnProperty()
when checking file specification objects (prevents problems whenObject.prototype
has been modified). (Issue #352)
