See https://github.com/maxmind/GeoIP2-java/releases and https://github.com/maxmind/MaxMind-DB-Reader-java/releases.

Pretty straightforward version bumps all around.

LGTM. (good to merge, from my POV)

Just a note on the addition of requires java.net.http:

1. maxmind/GeoIP2-java has triggered the need for the java.net.http module. See the release note [1]. The release note says that the use of Apache HttpClient has been replaced with java.net.http.HttpClient, but strangely I see no previous Gradle (or otherwise) dependency on the Apache HttpClient. Maybe we never exercise this particular functionality of maxmind/GeoIP2-java ?

2. Server does not strictly require java.net.http, since server does not currently use anything from the java.net.http module. The use of requires here simply ensures that the java.net.http is in the boot layer, which allows the geoip plugin to access it there. Alternatively, we could add java.net.http to the --add-modules in the CLI, see ServerProcess.java [2]

3. Neither the requires on server, nor the --add-modules, should be necessary. The plugin layer should find JDK modules, not in the boot layer, in the JDK module finder. There could be a bug here, but I thought that this "just worked" - I'll take a look.

Yeah, that's my understanding. We download the files ourselves and then manage them locally via indexes and files, from the POV of the geoip library, there's no downloading to do.
