Hi all,
There was a bug in sampling introduced in Stan v2.10.0 (
stan-dev/stan#1972) that was fixed for this version. We suggest upgrading from v2.10.0 to v2.11.0 immediately.
For users of Stan.jl, MatlabStan, or StataStan, upgrading the underlying CmdStan installation will be sufficient.
RStan and PyStan will be patched and released soon.
If you have any questions or difficulties with the new version, please let us know on the
stan-users list.
Daniel
