+[sTeX3](https://github.com/slatex/stex) is a complete rewrite of sTeX - An infrastructure
+for semantic preloading of LaTeX documents - in the LaTeX3 framework. It has just been
+released to [CTAN](https://ctan.org) the Comprehensive TeX Archive Network, and will be
+part of [TeXLive 2022](https://www.tug.org/texlive/) due out in April.  
+
+After almost 15 years, sTeX needed a complete makeover to regularize syntax, weed out
+unused and deprecated features, and synchronize it better with the
+[MMT](https://uniformal.github.io) system and functionality. 
+
+Compared to sTeX1, the new implementation does away with the need for external systems in
+the PDF workflow, allows to add sTeX functionality to arbitrary document classes, and
+completely reworks the XML-based content generation. Instead of using a
+[LaTeXML](https://math.nist.gov/~BMiller/LaTeXML/) fork we use
+[RusTeX](https://github.com/slatex/RusTeX/) a new TeX engine that directly interprets the
+sTeX3 packages and generates semantically annotated XHTML5 which can then be harvested by
+[MMT](https://uniformal.github.io) for further knowledge management services. 
+
+Further development of the sTeX ecosystem (the packages, an IDE, RusTeX, ...) will
+continue on [sLaTeX group on GitHub](https://githhub.com/sLaTeX).

+After almost 18 months of development, [MMT](https://uniformal.github.io) - the flagship
+system of the KWARC group - has been released in [version
+22](https://github.com/UniFormal/MMT/releases/tag/v22.0.0).
+
+The long development time of this release has been a consequence of the growing
+inter-dependency of the system-near library and the system code, which led to serious
+maintenance problems in the past. Another problem was that a lot of dead code had
+accumulated over the last decade. 
+
+These problems have been addressed in version 22 (see the [release
+notes](https://github.com/UniFormal/MMT/releases/tag/v22.0.0) for details) and we hope
+that MMT can now serve as a much more stable basis for mathematical knowledge management
+and we can return to a faster release cycle for the future.
