• add support for long integers in Python 2.7

• update test-skipping decorator to use standard version requirement strings

• Bugfix: seeding an object schema with a "required" keyword caused an error

• Docs: fix mislabeled method

This version was a total overhaul. The main change was to split Schema into three separate classes, making it simpler to add more complicated functionality by having different generator types to handle the different schema types.

1. SchemaNode to manage the tree structure

2. SchemaGenerator for the schema generation logic

3. SchemaBuilder to manage the public API

Interface Changes

• SchemaBuilder is the new Schema

• to_dict() is now called to_schema()

To make the transition easier, there is still a Schema class that wraps SchemaBuilder with a backwards-compatibility layer, but you will trigger a PendingDeprecationWarning if you use it.

Seed Schemas

The merge_arrays option has been removed in favor of seed schemas. You can now seed specific nodes as list or tuple instead of setting a global option for every node in the schema tree.

You can also now seed object nodes with patternProperties, which was a highly requested feature.

Other Changes

• include "$schema" keyword

• accept schemas without "type" keyword

• use "anyOf" keyword to help combine schemas

• add SchemaGenerationError for better error handling

• empty "properties" and "items" are not included in generated schemas

• genson executable

  • new --schema-uri option

  • auto-detect object boundaries by default

• Docs: add installation instructions

• Docs: Python 3.6 is now explicitly tested and listed as compatible.

• Bugfix: add_schema failed when adding list-style array schemas

• Bugfix: typo in readme

• Bugfix: Options were not propagated down to subschemas.

• Bugfix: Empty arrays resulted in invalid schemas because it still included an items property.

• Bugfix: items was being set to a list even when merge_arrays was set to True. This resulted in overly permissive schemas because items are matched optionally by default.

• Improvement: Positional Array Matching - In order to be more consistent with the way JSON Schema works, the alternate to merge_arrays is no longer never to merge list items, but instead to merge them based on their position in the list.

• Improvement: Schema Incompatibility Warning - A schema incompatibility used to cause a fatal error with a nondescript warning. The message has been improved and it has been reduced to a warning.
