On behalf of the Spring Data team I'd like to announce the first (and final) release candidate of Spring Data train Ingalls. The release ships over 310 issues fixed (some of them previously released with Hopper service releases). The most important new features are:

• Upgrade to Spring 4.3(.5) as baseline - #294.
• Support to easily expose domain events as Spring application events from aggregate roots - DATACMNS-928.
• Support for exists projection from derived query methods - DATACMNS-875.
• Support for Javaslang's Option, collection and map types on repository query methods - DATACMNS-937, DATACMNS-940.
• Added Spring Data LDAP module taking over the repository implementation of Spring LDAP.
• Support for MongoDB aggregation operators added in latest releases - DATAMONGO-1536.
• Stream execution now rejects invocation without surrounding transaction in JPA - DATAJPA-1023.
• Support for annotation based indexing and expirations in Gemfire - SGF-106, SGF-516.
• Support for CORS configuration in Spring Data REST - DATAREST-573.

The release of course contains a lot more features. Find the complete list of fixed tickets here and a more curated change log for the most significant features in Ingall in our release train wiki. We're shooting for a GA release mid to end of January with a couple of bug fixes and documentation polishing applied. So it's the perfect time to give the current release a spin and help us ironing out glitches.

As always, feedback is appreciated via the bug tracker, the Gitter channel, on StackOverflow or even Twitter. To round things off, here's the list
