katex

New Features:

• Added support for some \begin/\end environments, including support for array, matrix, pmatrix, bmatrix, vmatrix, and Vmatrix
• Added support for optional \sqrt arguments, e.g. \sqrt[3]{x}
• Bower package is now available: run bower install katex to download the built files

Other changes:

• Add a display mode flag to the cli
• Expose an unstable __parse method for retrieving the parse tree
• Prevent elements from inheriting text-indent

Breaking changes:

• The greediness of the \color function has changed to maintain compatibility with MathJax, so expressions like \color{red}\text{a} will no longer work and instead need to be rewritten as \color{red}{\text{a}}

New features:

• Add an auto-render extension for automatically rendering math on a page
• Add support for \phantom
• Add \#, \&

Other changes:

• Fixed spacing for \odot, \oplus, \otimes, \oslash, \bigtriangleup, \bigtriangledown, \dagger, \diamond, \star, \triangleleft, \triangleright
• Fixed MathML handling of text operators
• Removed !important from MathML hiding rules, so they can be overridden

New features:

• Added accessibility through the use of MathML
• Added the ability to render math in display mode, centered on a single line in display style
• Add support for new symbols: \aleph, \amalg, \approxeq, \ast, \asymp, \backepsilon, \backprime, \backsim, \backsimeq, \Bbbk, \because, \beth, \between, \bigcirc, \bigstar, \blacklozenge, \blacksquare, \blacktriangle, \blacktriangledown, \blacktriangleleft, \blacktriangleright, \bowtie, \Box, \boxminus, \boxplus, \boxtimes, \bullet, \bumpeq, \Bumpeq, \Cap, \cdotp, \centerdot, \circeq, \circlearrowleft, \circlearrowright, \circledast, \circleddash, \circledS, \clubsuit, \complement, \Cup, \curlyeqprec, \curlyeqsucc, \curlyvee, \curlywedge, \curvearrowleft, \curvearrowright, \dag, \daleth, \dashleftarrow, \dashrightarrow, \dashv, \ddag, \ddagger, \diagdown, \diagup, \Diamond, \diamondsuit, \digamma, \divideontimes, \doteq, \Doteq, \doteqdot, \dotplus, \doublebarwedge, \doublecap, \doublecup, \downdownarrows, \downharpoonleft, \downharpoonright, \ell, \eqcirc, \eqsim, \eqslantgtr, \eqslantless, \equiv, \eth, \exists, \fallingdotseq, \Finv, \flat, \forall, \frown, \Game, \geqq, \geqslant, \gg, \ggg, \gggtr, \gimel, \gnapprox, \gneq, \gneqq, \gnsim, \gtrapprox, \gtrdot, \gtreqless, \gtreqqless, \gtrless, \gtrsim, \gvertneqq, \hbar, \heartsuit, \hookleftarrow, \hookrightarrow, \hslash, \Im, \intercal, \Join, \ldotp, \leadsto, \Leftarrow, \leftarrowtail, \leftharpoondown, \leftharpoonup, \leftleftarrows, \leftrightarrow, \Leftrightarrow, \leftrightarrows, \leftrightharpoons, \leftrightsquigarrow, \leftthreetimes, \leqq, \leqslant, \lessapprox, \lessdot, \lesseqgtr, \lesseqqgtr, \lessgtr, \lesssim, \lgroup, \lhd, \ll, \llcorner, \Lleftarrow, \lll, \llless, \lmoustache, \lnapprox, \lneq, \lneqq, \lnsim, \longleftarrow, \Longleftarrow, \longleftrightarrow, \Longleftrightarrow, \longmapsto, \longrightarrow, \Longrightarrow, \looparrowleft, \looparrowright, \lozenge, \lrcorner, \Lsh, \ltimes, \lvertneqq, \mapsto, \measuredangle, \mho, \mid, \mp, \multimap, \nabla, \natural, \ncong, \nearrow, \nexists, \ngeqq, \ngeqslant, \ngtr, \ni, \nleftarrow, \nLeftarrow, \nleftrightarrow, \nLeftrightarrow, \nleqq, \nleqslant, \nless, \nmid, \nparallel, \nprec, \npreceq, \nrightarrow, \nRightarrow, \nshortmid, \nshortparallel, \nsim, \nsubseteqq, \nsucc, \nsucceq, \nsupseteqq, \ntriangleleft, \ntrianglelefteq, \ntriangleright, \ntrianglerighteq, \nvdash, \nvDash, \nVdash, \nVDash, \nwarrow, \ominus, \owns, \parallel, \perp, \pitchfork, \prec, \precapprox, \preccurlyeq, \preceq, \precnapprox, \precneqq, \precnsim, \precsim, \propto, \Re, \restriction, \rgroup, \rhd, \Rightarrow, \rightarrowtail, \rightharpoondown, \rightharpoonup, \rightleftarrows, \rightleftharpoons, \rightrightarrows, \rightsquigarrow, \rightthreetimes, \risingdotseq, \rmoustache, \Rrightarrow, \Rsh, \rtimes, \searrow, \sharp, \shortmid, \shortparallel, \sim, \simeq, \smallfrown, \smallsetminus, \smallsmile, \smile, \spadesuit, \sphericalangle, \sqcap, \sqcup, \sqsubset, \sqsubseteq, \sqsupset, \sqsupseteq, \square, \Subset, \subseteqq, \subsetneq, \subsetneqq, \succ, \succapprox, \succcurlyeq, \succeq, \succnapprox, \succneqq, \succnsim, \succsim, \Supset, \supseteqq, \supsetneq, \supsetneqq, \swarrow, \therefore, \thickapprox, \thicksim, \triangledown, \trianglelefteq, \triangleq, \trianglerighteq, \twoheadleftarrow, \twoheadrightarrow, \ulcorner, \unlhd, \unrhd, \upharpoonleft, \upharpoonright, \uplus, \upuparrows, \urcorner, \varkappa, \varpropto, \varsubsetneq, \varsubsetneqq, \varsupsetneq, \varsupsetneqq, \vartriangle, \vartriangleleft, \vartriangleright, \vdash, \vDash, \Vdash, \Vvdash, \wp, \wr, \yen

Other changes

• Removed unused greek fonts

New features

• Add support for \binom
• Add support for \over and \choose
• Add \partial, \subset, \supset, \subseteq, \supseteq, \cap, \cup, \setminus, \neg, \lnot, \top, \bot, \emptyset, \varnothing, \land, \lor, \wedge, \vee, \notin, \nsubseteq, \nsupseteq, \models
