https://github.com/dlang-community/containers/compare/v0.8.0-alpha.19...v0.8.0

• Added front and back methods to the TreeMap container.
• Fixed the visibility of the nodeCapacity field of the TTree container.

Changes from alpha.15:

• Fix memory corruption that can happen when references to GC-allocated memory are stored in an OpenHashSet container
• Get the unit tests to compile with DMD 2.087.0
• Changed the way that the ContainerElementType template works: It should now correctly determine that methods that return elements by ref should return const references when the container itself is const but the element type is mutable.

Improve the performance of some of the containers when compiling with LDC.

Improve the worst-case performance of mapping hash codes to array indexes.
