Released June 20th, 2016.

 * Added the function `LSHSearch::Projections()`, which returns an arma::cube with each projection table in a slice (#663).  Instead of `Projection(i)`, you should now use `Projections().slice(i)`.
 * A new constructor has been added to `LSHSearch` that creates objects using projection tables provided in an arma::cube (#663).
 * `LSHSearch` projection tables refactored for speed (#675).
 * Handle zero-variance dimensions in DET (#515).
 * Add `MiniBatchSGD` optimizer (src/mlpack/core/optimizers/minibatch_sgd/) and allow its use in mlpack_logistic_regression and mlpack_nca programs.
 * Add better backtrace support from Grzegorz Krajewski for Log::Fatal messages when compiled with debugging and profiling symbols. This requires libbfd and libdl to be present during compilation.
 * CosineTree test fix from Mikhail Lozhnikov (#358).
 * Fixed HMM initial state estimation (#600).
 * Changed versioning macros `__MLPACK_VERSION_MAJOR`, `__MLPACK_VERSION_MINOR`, and `__MLPACK_VERSION_PATCH` to `MLPACK_VERSION_MAJOR`, `MLPACK_VERSION_MINOR`, and `MLPACK_VERSION_PATCH`. The old names will remain in place until mlpack 3.0.0.
 * Renamed `mlpack_allknn`, `mlpack_allkfn`, and `mlpack_allkrann` to `mlpack_knn`, `mlpack_kfn`, and `mlpack_krann`. The `mlpack_allknn`, `mlpack_allkfn`, and `mlpack_allkrann` programs will remain as copies until mlpack 3.0.0.
 * Add `--random_initialization` option to `mlpack_hmm_train`, for use when no labels are provided.
 * Add `--kill_empty_clusters` option to `mlpack_kmeans` and `KillEmptyClusters` policy for the `KMeans` class (#595, #596).
