v1.7.0

What's Changed

• Adds utility to get all symbol text declared in one or more schemas in #282
• Improves performance of annotations constraint in #287
• Add optimization to fail-fast on annotations in #285
• Improves validation performance of types defined in the spec in #286

• Remove extraneous clones in TypeNamed and ViolationChild in #296
• Release v1.7.0 in #297

More Details

• You can expect a significant performance improvement for the isValid() and validate() APIs because of the improvements to the spec types and the removal of unnecessary cloning of IonValues
• If you use Ion annotations for tagging types, there is a opt-in feature that will speed up the validation performance and reduce noise in the violations output. For more information, see the documentation for IonSchemaSystemBuilder.failFastOnInvalidAnnotations().

Full Changelog: v1.6.0...v1.6.1

v1.6.0

Quick Hits

• Adds a model for Ion Schema that can be used for programmatically introspecting, constructing, or otherwise manipulating schemas and type definitions. This model is currently marked as experimental and subject to potentially breaking changes. This release includes reader/deserializer for Ion Schema 2.0, and a writer/serializer is to come in a future release.
• Adds CLI tool for fixing transitive imports—see the launch announcement for details
• The schema_footer is now optional regardless of whether or not a schema_header is present, and can be used to delimit the end of a schema document in a larger stream of Ion.
• Adds ISL Commons—an Ion Schema library containing type definitions for things that are common to other programming languages. It includes types such as uint8, int32, float32, date. See also amazon-ion/ion-schema-schemas#13.

Full Changelog: v1.2.0...v1.2.1

Release 1.2.0

What's Changed

This release includes the following enhancements:

• Provides graceful handling of circular imports (#157)
• Two enhancements to existing constraints:
  • Adds a closed:: modifier for the annotations constraint (#159)
  • Ranges are can now be embedded in the list of values for valid_values (#163)
• A new constraint (utf8_byte_length) for validating the number of bytes required to encode a string or symbol in utf8 (#162)
• Two new Authority implementations
  • ResourceAuthority (#173)
  • InMemoryMapAuthority (#180)
• ion-schema-schemas is now bundled in the ion-schema-kotlin JAR and can be accessed using ResourceAuthority. (#173)
• Builder option to provide a callback for non-fatal warnings from the IonSchemaSystem (#180)

Additionally, the following bugs have been fixed:

• Imports where the schemaId is an Ion symbol rather than an Ion string no longer results in an error. (#158)
• Declaring two type definitions with the same name in a single schema will result in an error rather than silently discarding one of them. (#171)
• Imports are no longer resolved transitively. WARNING—this is a potentially breaking change, so you must explicitly opt into this fix using the allowTransitiveImports(false) builder option. (#180)
  • This change will become the default behavior in ion-schema-kotlin-2.0.0.
  • It is strongly recommended that you use the withWarningMessageCallback builder option to help determine if and where your application would be affected by this change even if you do not enable this fix.
