Brushfire 0.8.0

This release introduces artifacts for Scala 2.12 and drops 2.10 support. It updates the Bonsai (to 0.3.0), Algebird (from 0.12 to 0.13), Scalding (from 0.16.1-RC3 to 0.17.4), Chill, and some test dependencies.

This release should be source-compatible with 0.7 releases, with two exceptions: Node#fold and FullBinaryTreeOpsForAnnotatedTree#foldNode, which have been changed to match the latest Bonsai API.

v0.7.5

• Update algebird & scalding

v0.7.4

• Split brushfire-core into brushfire-tree, brushfire-training, and brushfire-serialization
• Bump version of Bonsai to 0.2.1 (fixes bug in serialization)

v0.7.3 BROKEN - DO NOT USE

• Bump version of Bonsai to 0.2.1 (fixes bug in serialization)

v0.7.2

• better support for Bonsai serialization
• memory efficiency improvements when training in local mode

v0.7.1

• Improves performance of TreeTraversal

v0.7.0

• All split nodes are restricted to binary splits only
• Simplified predicates
• Support generalized Bonsai trees in TreeTraversal
• New JSON serialization format

This release is notable because it breaks the JSON serialization format. There is a migration script provided under scripts to migrate models trained with previous versions of the scalding trainer over to the new format. This will only work for binary models with simple predicates though.
