Since we found out that many users were not aware of our release notes over at the documentation at [http://docs.pumas.ai](http://docs.pumas.ai) we figured it was useful to announce a few of the past releases here.

Back in August we released v2.2 and a little later in the year (September) we released a bug fix release for this version as well. Version 2.2 introduced a handful of features and quite a few bug fixes. Most notable change were

- Prediction corrected VPCs
- A new closed for solution for a model with a parent-metabolite dynamics with only one metabolite
- More flexible support for incomplete data models in SAEM
- All apps are collected in one app for easy discoverability
- Model builder app for quickly generating model code in a GUI

as well as many bug fixes.
