EuroTcl 2016: Semantic Versioning (Jan Nijtmans)

[@MdotWelblech]

"Since version 3, TeX has used an idiosyncratic version numbering system, where updates have been indicated by adding an extra digit at the end of the decimal, so that the version number asymptotically approaches π. This is a reflection of the fact that TeX is now very stable, and only minor updates are anticipated. The current version of TeX is 3.14159265" - en.wikipedia.org/wiki/TeX
