I've been trying to sample from multiple Stan models in parallel, and chains terminate unexpectedly every single time.
I tried all kinds of workarounds without any success, and eventually found the following bug report:

Containers seemed like overkill; then I discovered `unname` and found that it worked! What a relief. I still have no idea *why* this is necessary ...
CmdStan 2.33.0!
This new release brings two new exciting features:
- a new Stan language type - tuples
- a new VI algorithm - Pathfinder.
The release also features some new functions - mostly related to tuples, and other minor improvements.
There are also a number of long-deprecated language features that have now become errors with this version.
