• (enhancment) Explicitly include MLJIteration, re-exporting its methods and types, so that using MLJIteration is no longer required to make use of the newly released package (#139). For documentation, see here.
• Update MLJBase and import the new packages MLJOpenML and MLJSerialization, which provide functionality contained in the older MLJBase versions. Should have no effect on the MLJ user (JuliaAI/MLJBase.jl#416)

v0.16.0

MLJ v0.16.0

Diff since v0.15.2

Release notes:

Update MLJModels and MLJBase compatibility requirements. Includes some breaking changes. Most significantly note that @load now returns a model type instead of an instance (see https://github.com/alan-turing-institute/MLJ.jl/blob/dev/docs/src/loading_model_code.md). For full list of changes, see:

MLJBase 0.17.0 release notes
MLJModels 0.14.0 release notes

Closed issues:

• Can't use @load within a module (#321)
• Add option to cache data at nodes of learning networks to avoid repeating operations (transform, predict, etc) (#702)

Merged pull requests:

• Documentation updates for adding data front-end to model implementations (#727) (@ablaom)
