## Description <!-- Describe your change and the problem it solves. Link to the related issue(s) if they exist. --> **Changes made:** 1. **`grails-doc/src/en/guide/deployment/deploymentTasks.adoc`** — Added a new `[[java25-memory]]` subsection "Java 25 Memory Considerations" under the existing "Memory, storage, and logging" section. It explains that metaspace is unbounded by default on Java 25, provides concrete `-XX:MaxMetaspaceSize` examples for both fixed and percentage-based heap sizing, shows how to add the flag to a systemd `ExecStart`, covers the optional free-ratio tuning flags, and includes a NOTE about the deprecated `-XX:+/-UseCompressedClassPointers` flag. 2. **`grails-doc/src/en/guide/deployment/deploymentStandalone.adoc`** — Added a one-sentence cross-reference to the new `[[java25-memory]]` anchor immediately after the existing "Size the heap for your workload…" sentence, directing readers to the full guidance. 3. **`grails-doc/src/en/guide/upgrading/upgrading80x.adoc`** — Added section **85. Java 25 Memory Requirements** at the end of the upgrade guide. It summarises the metaspace-unbounded change, gives the same `-XX:MaxMetaspaceSize` command-line examples, lists the deprecated `UseCompressedClassPointers` flag with migration steps, and cross-references the deployment guide for full details.
