v2.26.0 (26 January 2021)
- Improved performance for assigning to slices of matrices and vectors and vector-style indexing (#2962, #2964, #2965, #2973).
- Improved error messages on range checks. (#2978)
- Allowed Stan CSV files to have first column be any Stan variable name, not just "lp__".
- Removed .eval() in rvalue() where applicable. (#2974)
- Allowed reader to accept Eigen vector and use Eigen Map to access inputs. (#2955)
- Allowed functions in reader to output a
var_value<Eigen::Matrix<T, R, C>>. - Added assignment to
var_value<Eigen::Matrix<T, R, C>>. - Added rvalue overloads for
var_value<Eigen::Matrix<T, R, C>>.

Tagging v2.25.0-rc1
v2.24.0 (28 July 2020)
New Features
- math updated to 3.3.0 (release notes)
std::chronois now used for all timing purposes- fixed a bug with generated quantities for vectors of length 1
- added
recover_memoryfor normal exit oflog_prob_grad - replaced the use of
boost::functions/metaprograms in favor ofstd::where applicable

v.2.22.1 (31 January 2020)
Updated math version to v3.1.1
v.2.22.0 (24 January 2020)
New Features
- validate_dims in stan::io::var_context vas made a virtual function which allows its implementation for JSON data which is needed to accepts arrays where any dimension is size 0
- replaced Eigen vectors of strings with std::vectorstd::string
- replaced stan::math::domain_error with throw_domain_error
- added const noexcept accessors to the stepsize adaptation class which allows developers to query the adaptation parameters in contexts where it's natural to have a const sampler (logging, serialization, ...)

v2.21.0 (18 October 2019)
v.2.21.0 (18 October 2019)
We are now using TBB for threading in map_rect. With performance tests on a non-trivial map_rect model we have observed speedups of up to 20% on Windows, 70% on Linux and 30% on MacOS. Speedups were observed for both Intel and AMD CPUs. This has a downstream license effect too - we can no longer be bundled in a single distributed binary with GPLv2 code.
Here are some speedups on a non-trivial model with 12 cores:
New Features
- Add Intel TBB (#2769)
- Add automated maintanence and cleanup via clang-tools to makefile (#2805)
- Use Welford's algorithm for Variance Estimates in src/stan/analyze (#2819)
- Adds additional no-u-turn checks across subtrees to avoid missing u-turns for approximately iid normal models (#2800)
- Add gp kernels to language (#2739)
- Update rhat and ess (#2794)
Bug Fixes
- Fix const logic and size check (#2822)
- Add ifdef for R new_model (#2798)
- Add g_ to name of g vector name in ps_point (#2832)

v2.20.0 (18 July 2019)
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)
