Notes

This release is a feature release and adds support for MicroProfile 3.0 and
support for Hibernate as a JPA provider. It also includes a number of additional
bug fixes and enhancements.

Note: MicroProfile 3.0 breaks compatibility with MicroProfile 2.2 -- specifically
in the area of Metrics. Since Helidon 1.3 continues to support MicroProfile 2.2
your applications that depend on the MicroProfile 2.2 APIs should continue to work
when you upgrade to Helidon 1.3. But when you switch to MicroProfile 3.0 you will
likely need to change code that uses the MicroProfile Metrics API. For more
information see sections 6.5 and Chapter 7 of
microprofile-metrics-spec-2.0.pdf

As part of this release we are also deprecating APIs for possible removal
in a future release. Please see the Deprecations section below.

Deprecations

The following APIs are deprecated and will be removed in a future release:

  • MicroProfile 2.2 and earlier. Use MicroProfile 3.0.
  • The @SecureClient annotation. Security propagation is now automatic across the MicroProfile and Jersey REST clients.
  • UserStore in basic authentication. Replaced by SecureUserStore.
  • All methods that use Span in Webserver APIs (and Security etc.). Use SpanContext instead.
  • All methods that provide general health checks and not readiness or liveness checks. For example
    use HealthSupportBuilder.addLiveness() instead of HealthSupportBuilder.add()
  • io.helidon.common.reactive.SubmissionPublisher
  • The io.helidon.service.configuration package.
  • The io.helidon.common.reactive.valve package.
  • Any other classes and methods that have been annotated as deprecated.
