What to Expect from the 6th Edition?
First, a critical clarification: As of my knowledge cutoff in early 2025, there is no official 6th edition of Spring Boot in Action by Craig Walls. The latest published edition is the 5th edition (which covers Spring Boot 2.x). The 6th edition (covering Spring Boot 3.x) has been rumored or planned, but not yet released. Any references to a "6th edition PDF" online likely refer to unofficial, incomplete, or pirated content. 6th Edition Spring in Action by Craig Walls
