Hi, Spring fans! Welcome to another installment of This Week in Spring! This week I’m in blizzard-besieged Boston, Massachusetts, for the epic Spring One Tour Boston event. Unfortunately, due to this crazy snow storm/blizzard, the event’s been postponed one day as we all grapple with the weather. Hope you were able to join the Spring Boot 2.0 launch webinar! If not the replay will be available here and don’t forget to check out the launch blog!
Snow or no snow! The show must go on, at least here on the Spring blog, so without further ado:

@Modifyfor marking queries that perform DML or DDL. Modifying queries will return type
Booleanwhen the number of updated rows is greater 0. This shouldn’t be used for DML statements since it will always return false.
- Spring Web Flow lead Rossen Stoyanchev has just announced Spring Web Flow 2.5. This release provides an upgrade path for applications using Web Flow to Spring Framework 5 with Java 8, Servlet 3.1, Hibernate 5, Tiles 3, and JSF 2.2 as minimum requirements.
