+------------
+- 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)
