After several beta versions (including the one used for the 2021 DynModTox course), I have now released a version that gets the official v6.0 designation. There's been a lot of changes, relative to the previous official version 5.2. Most importantly, support for the parallel-processing toolbox and extended LPx/EPx calculations. However, under the hood, many more bells and whistles. All details are collected in the version log.

There will be errors and glitches in this version. So please let me know if you run into something. This won't be the last version

Also released, a package for TKTD analyses with standard DEB. This is a tricky package to use! However, it is good to have the option to use the more complex standard DEB model with the same tools as used for the simplified DEBtox2019 model.
