October 2025 focused on strengthening upgrade automation in openrewrite/rewrite-spring: delivering Spring Security migration recipes for 6.4 and 6.5 aligned to Spring Boot upgrades 3.4/3.5, with YAML configs and safeguards to run only during the relevant upgrade window, plus a documentation fix for the MigrateItemWriterWrite recipe to reflect Spring Batch 5.x changes. These efforts reduce upgrade risk, accelerate migrations, and demonstrate robust cross-cutting skills in Java, Spring ecosystem migrations, and OpenRewrite configuration.
