  1. Tax-Calculator 3.2.1 released. Fixes a bug in a CTC parameter value.
  2. The Tax-Foundation’s capital-cost-recovery model joins the PSL Catalog.
  3. OG-Core, a general framework for overlapping generations macroeconomic models, has been released. There are currently two country specific applications, OG-USA and OG-UK.

Thanks, @jdebacker. A quick clarifying question: Is it correct that now OG-Core is cataloged and both OG-USA and OG-UK are incubating?
