v.2.20.0 (18 July 2019)
New Features
- Update effective sample size calculations, with a small change to the autocovariance function, to use split chains (#2774)
- Add stan::model::model_base base class and and stan::model::model_crtp static adapter class for constructing models. (#2785)
- Allow ts and t0 to be parameters, complete ode_test, and extend the integrate_ode_* stan models (#2791)
- Add the GP covariance functions to the language (primitives of some popular materns, a dot product, and the periodic) (#2758)
- Update Eigen includes to allow compilation with new plugin methods (#2754)
- Add gp kernels to language (#2739)
Bug Fixes
- Multi-unit compilation of base_xhmc.hpp. (#2775)
- Declaring a size zero simplex in a Stan program will halt the program. (#2773)
Other
- Defer to Eigen's copy constructor now for assignment ( faster matrix assign ) (#2784)
- Rethrow_located also takes in a string to specify the location. (#2770)
- Faster indexing (#2766)
- Fixed generator so that matrix indexing uses most efficient access strategy (#2749)
