Edward R: c++ implementations of new R-hat and ESS diagnostics.
Simon: Working on adaptive leapfrog, more work on inference.
Andrew: Making some progress getting hier models faster.
Ben G: Rstan release still held up, just one package holding us back.
Reviewing some books. Working on papers.
Charles: In Finland, focusing on nested Laplace approx, doing good speed increases. Working on algebraic solver. Working on tutorial for StanCon.
Mitzi: User interface, cmdStanPy work continues, standalone documentation. Met with Pyladies. Planning on some meetups.
Leah C: Just graduated with PhD. Linking Bayesian causal inference.
Sean: Compiler work, benchmarked tensor flow prob with Stan. Same speed on LR models. Measuring gradients/sec. Planning offsite developers meeting.

Breck: StanCon continues, $100k contribution from Facebook to NumFOCUS matching Schmidt funds. 20% to matching goal. Lots of SGB activity.
Bob: Worked with Shira on modeling. Finished autodiff tests refactor. Waiting on PR review. Working on speeding up compilation.
Report on Math meeting: went through PRs that are still open.
Bob: Do we allow Stan derived packages in Case Studies?
Breck, Jonah and Sean will look into a general solution to allowing this.
