I'm trying to check if a problem occurs in previous versions of Liberty. Current version is 8.5.5.3 and I would like to check it on 8.5.5.1 and 8.5.5.2. Is it possible to find it somewhere ?
Looking at the downloads page I can find only the latest version.
Try from here Fix list for IBM WebSphere Application Server V8.5. You will find Liberty for Developers in given version as one of possible downloads.
