Spring Security 4.0.0.M2 发布，现已提供在 Spring Milestone repository。
主要改进内容：
Support for WebSocket Security using Spring's messaging abstraction
Spring Data integration
Spring Session was produced out of the work necessary for this release. In an application server independent way you can easily use a custom backend (i.e. Redis) as the HttpSession implementation. See the project page for additional features of this exciting new project.
Enhancements and fixes to the testing support
Easier integration with MockMvc through SecurityMockMvcConfigurers
You no longer need to specify WithSecurityContextTestExecutionListener on your tests
@WithSecurityContext works even with custom SecurityContextRepository implementations
Support for digest and certificate based authentication testing
Support nested static groups in LDAP Authentication
Lots of integration tests added to the sample applications
Updated minimum version of Spring 4.1 RC2. This was necessary for enough of the features, that it made sense to do across the board
