We are happy to announce the availability of a brand new version of Oracle JDeveloper and Oracle ADF :
Version 12.2.1.1
While numbering wise this might seem like a very minor version, in reality there are a host of new features in this version that you can leverage in your applications. The features revolve around several key focus areas:
REST support
We added multiple capabilities to the "expose ADF Business Components as REST" functionality. This include features such as accessing multiple children objects, better query capabilities, exposing list-of-values as REST and configuration and monitoring functions.

These type of enhancement allow you to better leverage the investment you have in the ADF based business service when creating new type of UIs with technologies that relies on REST backends. For example native mobile apps (with frameworks as Oracle MAF) or JavaScript based client solutions (with toolkits such as Oracle JET).
New Data Visualizations
Continuing our commitment to making your application the source of knowledge at your company, we added a bunch of new visualization components such as picto charts, tag cloud, stock chart and more. We also added features and capabilities to existing chart components.

These capabilities allow you to show data in meaningful ways, turning data into information that can be easily understood.
UI Technology Improvements
This version adds several capabilities to reduce and better control client to server interactions from your ADF Faces UI.
Features such as pure client-side input date component, client side caching for table component, and code editor component enhancements help you reduce network traffic and optimize your UI performance.
We also continue to improve our support for using ADF based UIs on mobile devices with more options in the masonry layout, gestures on springboards, and support for the MS Edge browser.
Extended Groovy Support
A feature that might have flew below the radar for many developers is the introduction of Groovy based triggers in ADF Business Components, making it simpler to code logic in specific hook-points in the lifecycle of your services. In the new version we further extend this support adding triggers at both the EOs and VOs level.

There are many other new features in this release (as well as various bug fixes from previous versions).
The full list of new features is here.
Time for you to download the new version and start planning your upgrade.
