Hi,

Our team is looking to use WebSphere Liberty but when we look at download options we see v21 as well as v9. We don’t know which one we should get. Please clarify for us the differences between the 2 versions.

“WebSphere Liberty is a Java EE application server with a low-overhead Java runtime environment designed for cloud-native applications and microservices. WebSphere Liberty was created to be highly composable, start fast, use less memory and scale easily. On the other hand WebSphere Application Server Liberty Core is a lightweight Liberty-based edition. With WebSphere Application Server Liberty Core, you can rapidly build and deliver web applications that do not require

the full Java EE stack.”

WebSphere Liberty fixpack releases are versioned with the year of release as the first number. There has never been a Liberty fixpack with a major version of 9. WebSphere Application Server Liberty Core is a product versioned at 9 and the Liberty runtime fixpacks do not follow the product versioning.
