CmdStan v2.12.0 released!

[Daniel Lee]

Hi all,

CmdStan v2.12.0 is now available! For the full release notes, see:

• CmdStan: https://github.com/stan-dev/cmdstan/releases/tag/v2.12.0
• Stan: https://github.com/stan-dev/stan/releases/tag/v2.12.0
• Math: https://github.com/stan-dev/math/releases/tag/v2.12.0

Some notable changes:

• Some bugs were squashed in the language that prevented well-formed Stan programs from compiling. Please see the Stan release notes for more details.
• We've added these functions to the language since v2.11: mdivide_left_spd(), mdivide_right_spd(), cov_exp_quad(), append_row(), and append_col()
  
• We've added a new core team member, Charles Margossian!

There's one outstanding bug that we know about and it's existed in older versions of Stan. There should be a fix by the next version of Stan. If you're using lower truncation with a probability mass function, the normalizing constant isn't computed correctly. This only applies to discrete distributions when truncating with a only lower bound and the workaround is to write the truncated distribution by hand. See https://github.com/stan-dev/stan/issues/2054 for more details.

Thanks,

Stan Development Team
