.. _whats-new-2.2: ************************** 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`` and ``mlabeldtr`` 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`` to ``decimalsign``. (`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`` and ``mlabeldtr`` elements. * Ignore ``linebreak`` attribute on ``mspace`` when dimensional attributes are set. (`Issue #388 `_) * Implement ``rowspacing``/``columnspacing`` for ``mtable`` 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 the ``ignoreClass`` list so that ``tex2jax`` and ``asciimath2jax`` 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 when ``Object.prototype`` has been modified). (`Issue #352 `_)
