While reviewing https://github.com/stan-dev/cmdstan/pull/1134 I noticed the newlines were still logging and realized this PR hadn't been merged yet. @bob-carpenter do you have a chance to finish reviewing the latest changes?

[mitzimorris]

ready to merge when tests pass.

@WardBrian - why are ubuntu checks failing w/ complaint about g++?

[WardBrian]

Better to ask @serban-nicusor-toptal I think. Github did recently change the meaning of ubuntu-latest, but not recently enough that I think this would break it? https://github.blog/changelog/2022-11-09-github-actions-ubuntu-latest-workflows-will-use-ubuntu-22-04/

[WardBrian]

I think it actually is related to the ubuntu-latest changes, not sure clang-6 is available on 22.04 any longer. We can ignore it for this PR I think, I'll ask Nic to take a look
