 Stan Math Library Release Notes
 ======================================================================
 
+v2.19.0 (20 Mar 2019)
+======================================================================
+Slow to arrive, but fast to compute: Stan has GPU support!
+
+Stan 2.19 brings GPU-optimized computation to Stan users. The first supported 
+function is Cholesky decomposition, the main bottleneck of many common
+statistical models. Activating GPU support is easy - only a few lines are added
+to the configuration and no changes have to be made to the Stan model. Cholesky
+decompositions of larger matrices (including their gradients, when dealing with
+parameters) are then automatically transferred to the GPU with speedups ranging
+from 10 to 30, depending on matrix size and GPU.
+
+Other GPU-optimized matrix algebra primitives and common statistical models are
+soon to follow: matrix multiplication, lower triangular inverse,
+eigendecomposition, GP covariance functions and several GLMs. The implementation
+is based on OpenCL, so it can be used with any GPU and GPU programming-savvy
+users can also add their own custom OpenCL kernels.
+
