You can find highlights of what’s new in the What’s New in Spring Security 4.1 section of the reference. For details refer to the changelog links above.
Without the community we couldn’t be the successful project we are today. I’d like to thank everyone that created issues & provided feedback.
If you have feedback on this release, I encourage you to reach out via StackOverflow, GitHub Issues, or via the comments section. You can also ping me @rob_winch or Joe (our latest full time Spring Security team member) @joe_grandja on Twitter.
Of course the best feedback comes in the form of contributions.
