+## Core API
+
+### Additions
+
+
+**Package** `dynaml.models.neuralnets`
+
+ - Added `GenericAutoEncoder[LayerP, I]`, the class `AutoEncoder` is now **deprecated** 
+ - Added `GenericNeuralStack[P, I, T]` as a base class for Neural Stack API
+ - Added `LazyNeuralStack[P, I]` where the layers are lazily spawned.
+
+**Package** `dynaml.kernels`
+
+ - Added `ScaledKernel[I]` representing kernels of scaled Gaussian Processes.
+
+**Package** `dynaml.models.bayes`
+
+ - Added `*` method to `GaussianProcessPrior[I, M]` which creates a scaled Gaussian Process prior using the newly minted `ScaledKernel[I]` class
+ - Added Kronecker product GP priors with the `CoRegGPPrior[I, J, M]` class
+
+**Package** `dynaml.models.stp`
+
+  - Added multi-output Students' T Regression model of [Conti & O' Hagan](http://www.sciencedirect.com/science/article/pii/S0378375809002559) in class `MVStudentsTModel`
+
+**Package** `dynaml.probability.distributions`
+
+   - Added `HasErrorBars[T]` generic trait representing distributions which can generate confidence intervals around their mean value.
+
+
+### Improvements
+
+
+**Package** `dynaml.probability`
+
+ - Fixed issue with creation of `MeasurableFunction` instances from `RandomVariable` instances
+ 
+**Package** `dynaml.probability.distributions`
+
+  - Changed error bar calculations and sampling of Students T distributions (vector and matrix) and Matrix Normal distribution.
+
+**Package** `dynaml.models.gp`
+
+  - Added _Kronecker_ structure speed up to `energy` (marginal likelihood) calculation of multi-output GP models
+
+**Package** `dynaml.kernels`
+  - Improved implicit paramterization of Matern Covariance classes
+
+
+**General**
+
+  - Updated breeze version to latest.
+  - Updated Ammonite version to latest
