Stan 2.14 is out and it fixes thesampler bug in Stan versions 2.10 through 2.13.
Critical update
It’s critical to update to Stan 2.14. See:
RStan 2.14.1 PyStan 2.14.0.0 CmdStan 2.14.0The other interfaces will update when you udpate CmdStan.
The process
After Michael Betancourtdiagnosed the bug, it didn’t take long for him to generate a test statistic so we can test this going forward, then submit a pull request for the patch and new test. I code reviewed that and made sure a clean check out did the right thing and then we merged. We had a few other fixes in, including one from Mitzi Morris that completed the compound declare define feature. Then Mitzi and Daniel built the releases for the Stan math library, the core Stan C++ library, and then Daniel built the release for CmdStan. After that, Ben Goodrich and Jiqiang Guo worked on updating RStan and Allen Riddell worked through pile of issues for PyStan, and both were released.
