1.0.0

Notes

This is our 1.0 release and we have finished the API changes that we've
been working on over the last few months. From this point on we will
have much greater API stability. Thanks for your patience.

If you are upgrading from 0.11.0 note that media support (for example JsonSupport)
has moved to a top level media component. This means you might have to change
your dependencies and Java imports. For more details see: API Changes.

If you are upgrading from 0.10.5 or earlier you will likely need to change
your application due to a number of API changes we made since then.
For details on API changes see API Changes

Helidon 1.0 supports MicroProfile 1.2 with updated versions of the components.

Improvements

• WebServer: Add JSON-B (Yasson) support 388
• WebServer: Add Jackson support 351
• MicroProfile: update Hystrix to 1.5.18 391
• Examples: Change quickstart examples so that PUT uses json and not path param 399

Fixes

• WebServer: Fix for NullPointer when using Json support without configured charset 393

0.11.1

Notes

If you are upgrading from 0.10.5 or earlier you will need to change
your application (see Notes for 0.11.0 release). For details on API
changes see API Changes

If you are upgrading from 0.11.0 note that media support (for example JsonSupport)
has moved to a top level media component. Details
in API Changes.

Thanks for your patience with API changes. Once 1.0 is released this will
be behind us!

Improvements

• Security: Support PermitAll and DenyAll annotations 334
• WebServer: Implement RequestPredicate 325
• WebServer: Move media processing separated to a top level module 326
• Documentation: Add CDI extensions documentation 324
• Documentation: Various documentation and examples updates

Fixes

• Use JsonBuilderFactory instead of Json.create 330

0.11.0

Notes

We've made a number of API changes for this release in preparation for our
1.0 release. This means when you upgrade to 0.11.0 you will need to make
changes to your application. We apologies for the inconvenience, but we
wanted to get these changes in before 1.0. For details see
API Changes
