Hi Spring fans! Welcome to another installment of This Week in Spring! I just finished an online training today, Bootiful Kotlin, for O'Reilly today, and I'm doing another one on the 2nd of August (this Thursday), Reactive Spring, because the demand for the first one was so high. Don't miss it!

We've got a ton of things to look at, so without further ado, let's get to it!

• A friendly reminder that our Spring YouTube channel is awesome! There's so much good stuff and it's easy to get back to it. Just go to spring dot io dot video
• Are you using Spring Cloud Edgware? You should be aware that it's now entering it's EOL period, ending officially August 1st, 2019
• The good Dr. Mark Pollack has just announced Spring Cloud Data Flow 1.6 GA which contains a ton of new stuff including, task scheduling on PCF, dashboard improvements, Kubernetes support…

I am pleased to announce that Spring IO Platform Brussels-SR12 is now available from both repo.spring.io and Maven Central.

On behalf of the community I am pleased to announce the release of Spring Security 5.1.0.M2. This release comes with 100+ tickets closed.

As always we look forward to hearing your feedback! You can find the highlights below:

OAuth2

OAuth2 Resource Server

Basic support for OAuth2 Resource Servers has been added. See oauth2resourceserver

Authorization Code Flow

User’s can now obtain an access token using the OAuth 2.0 Authorization Code grant. See the authcodegrant sample.

WebClient and OAuth2 Support

There is now built in support for OAuth2 and WebClient support. The support allows:

• Adding the access token to the request

• Automatic refreshing of the access token when it expires

• Resolving the access token to use

…

All good things must come to an end, and for the 1.x line of Spring Boot that means we will need to cease maintenance twelve months from today, on Aug 1st 2019.

We will keep publishing occasional 1.5.x maintenance releases up until that point and will then end the branch.

Existing Spring Boot 1.x users should plan accordingly to ensure that they have upgraded to the latest 2.x version before that date. Please also note that Spring Boot 2.0 and above requires Java 8+, so if you're running Java 6 or 7 you should also plan on upgrading your JDK.

For detailed instructions on what you'll need to do to upgrade a Spring Boot 1.5 application to 2.0, check out the migration guide…

On behalf of the team, I am pleased to announce that Spring Boot 1.5.15 has been released and is is now available from repo.spring.io and Maven Central.

Spring Boot 1.5.15 includes 35 fixes, improvements and dependency updates. Thanks to all that have contributed with issue reports and pull requests.

If you haven’t already upgraded to Spring Boot 2, now is a great time to do so as the end of life announcement for 1.x’s has just been made.
