v1.2.0¶

Validation: Add opt-in Draft 2020-12 and 2019-09 compilers with registered references, input snapshots and native diagnostics. Default Draft 7 behavior remains unchanged. (#212, #213)

Logger: Preserve native TextMarshaler values and errors without invoking a failed marshaler twice. (#219)
Idempotency: Retain in-progress records until their execution deadline is strictly earlier than acquisition time. (#217)
HTTP: Reject invalid response headers before output and close retained bodies once when conversion fails. (#221)
Commons: Deduplicate NaN DynamoDB numeric set members and preserve numeric BOOL semantics for native Go values. (#222)
Metrics: Reject metadata writes to closed invocation scopes before calling user serializers. (#223)
JMESPath: Correct numeric conversion, JSON v2 serialization and null multi-select evaluation. (#226)
Validation: Preserve null oneOf branch indices and empty property names in JSON v2 diagnostics. (#215)

Complete first-party JSON v2 API adoption and expand finite compatibility audits across utility modules. Go 1.27 remains required.
Align all 27 maintained module versions and internal dependencies at v1.2.0. The frozen X-Ray SDK adapter remains excluded from new publication.
Improve quickstart, utility guides and documentation discovery. See publication acceptance for verified public consumers and source identity.

Logger: Add opt-in WrapRawHandler to log incoming JSON before typed decoding, retaining unknown members, empty/null values and exact numeric tokens. (#149)

HTTP Metrics: Add opt-in request-count metrics with bounded route dimensions. (#106)
Logger: Support streaming JSON marshalers and JSON v2 collection/error behavior while preserving exact numeric tokens. (#111)

Logger / Metrics: Reject invalid log field names without partial output, preserve decoded number precision and omit unspecified EMF storage resolution.
Parameters: Isolate SSM and Secrets Manager caches by effective request options; bypass caching for nonpositive lifetimes.
Batch / Idempotency Cache: Return every retry identifier when a full batch fails; retain unexpired in-progress records without execution deadlines to prevent duplicate execution.
Parser: Accept documented SES, Cognito and VPC Lattice inputs; preserve CloudFormation PhysicalResourceId and REST authorizer context.
HTTP: Honor compression quality values, validate structured +json bodies and preserve empty 204/205/304 responses.
HTTP: Preserve binary/preencoded bodies, cookies and repeated headers; bound error-handler redispatch and respect cancellation.
AppSync Events: Propagate per-handler authorization errors after publication workers finish.
Data Masking: Apply missing-field errors and warnings to erasure Rules as well as Fields.

Require Go 1.27 and adopt JSON v2: reject duplicate members and malformed Unicode, match typed field names case-sensitively and encode nil collections as [] / {}.
HTTP Metrics: New accepts variadic Options. Update explicitly nonvariadic constructor function types; direct calls remain valid.

Publish the first stable v1 release with the maintained API compatibility commitment and package usage examples.

2026-10-07 · Prerelease · GitHub Release

Preview HTTP request-count metrics and Logger streaming JSON support for the v1 API.

Batch / Idempotency Cache: Preserve full-batch retry identifiers and prevent reacquisition of unexpired in-progress records without execution deadlines.
Parameters: Separate caches by effective request options and bypass caching for nonpositive lifetimes.

Require Go 1.27 and strict JSON v2 decoding with case-sensitive typed field names and v2 collection defaults.
HTTP Metrics: Change New to accept variadic Options; explicitly nonvariadic constructor function types need updating.

Parameters: Correct UTF-8 replacement and strip leading BOMs from byte/binary transformations.
Parser: Correct UTF-8 replacement and BOM handling in Base64 text and gzip JSON decoding.
JMESPath: Decode malformed UTF-8 consistently in Base64 and gzip functions.
Signer: Keep request bodies available until asynchronous transport uploads finish.

Initial public release of 27 maintained modules, including Logger, OpenTelemetry Tracer, Metrics, Parameters, Parser, Batch and Idempotency.
