Changes

: Basically, to help you find your way aroundIn short, there is are 3 majors versionsmajor version branches::* 1995: Context Mark II, using good old TeX (which defaulted to the pdfTeX engine, but also supported ε-TEX, pdfTEX, XeTeX, and Aleph), stable and now . Now in maintenance-only mode,.:* 2005: ConTeXt Mark IV, using LuaTex TeX the LuaTeX engine,. This is the current stable version.:* 2019: ConTeXt LMTX, using LuaTex TeX engine, the lean and mean successor of LuaTeX (see [https://tug.org/TUGboat/tb40-1/tb124hagen-lmtx.pdf article]). :There are 2 different development trees for ConTeXt, called Mark II and Mark IV (MkII, MkIV). They are always released together in a single package because they share a fair amount of code. MkII is stable and is in maintenance-only mode, MkIV is actively developed, including several enhanced features and completely new font handling.:There are 3 different typesetting engines that work with ConTeXt: pdfTeX, XeTeX and LuaTeX. MkIV works only with LuaTeX, MkII with any one of the engines (pdfTeX is the default). Font setups (typescripts) differ per LuaMetaTeX engine. :ConTeXt releases are identified by a time stamp, e.g. ''2010.06.23 12:45''. At most times, there This is both a ''current'' and a ''beta'' ConTeXt release package available. As explained above, both packages contain MkII and MkIV, the difference between ''current'' and ''beta'' is that the latter contains the unstable developments to MkIV for testing by power usersdevelopment version.:Since "betas" are declared "current" only a few times a year and no bugfixes happen for "currents" (Each of the releases in contrary to "stable" those major branches in many software projects), you’re mostly better off with beta. It also has some bugs fixed, bur mostly some new bugsan ISO timestamp that functions as a minor version number. If you need a really stable and reliable system and can’t wait a few days : See [[ConTeXt history]] for a fix, stick with MkIIfurther details.
