Release 1.1.0

This release includes the following enhancements:

• adds Schema.isl and Type.isl, enabling access to the ISL underlying Schema and top-level Type objects (#143)
• enables custom schema caching logic (#144) via a new SchemaCache interface, SchemaCacheDefault implementation, and IonSchemaSystemBuilder.withSchemaCache(SchemaCache) method
• adds support in the regex constraint for compound character classes such as [A-Za-z0-9] (#147)
• adds Schema.getImports(), Schema.getImport(String), and a new Import interface to allow retrieval of the types imported by a schema (#148)
• provides graceful handling of redundant imports (#149); if schema A imports schemas B and C, which both import the same type from schema D, this is no longer results in an exception

Additionally, the following bugs have been fixed:

• Schema objects are now cached successfully (#141)
• AuthorityFilesystem now restricts file access to be within the specified basePath only (#142)
• all top-level type definitions are now required to have a name (#145)
  • IonSchemaSystemBuilder.allowAnonymousTopLevelTypes() may be used if the previous behavior is helpful until existing anonymous top-level type definitions are named (or removed)

Full list of changes: v1.0.1...v1.1.0

Full list of changes: v1.0.0...v1.0.1

Release 1.0.0

This release is a complete implementation of the Ion Schema Specification, and includes the following changes since the previous release:

• re-implements the regex constraint with java.util.regex.Pattern while not exposing Pattern's extra features (#119)
  • NOTE: with this change, the use of regex features not explicitly defined in the Ion Schema Specification should no longer work, and may produce an error
• adds test to verify inline type import behavior (and absence of type name conflicts) (#124)

Bugs fixed:

• adds correct propagation of type aliases when importing a schema (#123)
