@rok_cesnovar In the release notes it seems to suggest to use adaptation save_metric=1 but in trying it that fails. Adding just save_metric=1 after the adapt key seems to work.

A minor patch release (2.34.1) was released this morning to fix a few issues that came up in this release:

  • Compilation with the latest gcc resulted in complaints about missing headers
  • CmdStan had an indexing error which could cause programs to crash in certain situations
  • The probability distributions defined over cholesky matrices were not properly checking their inputs

And a few other changes. Thanks to all who reported these issues!
