A Note on Compatibility and Versioning

Versions

Apps are often updated to include new features or fix bugs. Each time an app is updated, its version number is changed. The version number is specified by the app developer, and often follows established norms, such as 1.0 -> 1.1 -> 2.0, or 1.0.1 -> 1.0.2 -> 1.2.0 and so on. Generally, the higher the numbers, the younger the version.

When viewing individual apps, the list of versions of that app are displayed, along with a download button for each version. In some cases, not all historical versions of apps are available, depending on the app. Usually you will want to download and install the latest available app for the version of Liferay you are using (See Compatibility below).

Compatibility

Some apps are written to work across a wide range of Liferay Platform releases. Others are dependent on a specific Liferay Platform release (or a handful of such releases). When viewing individual apps, each version of the app that is available also describes the range of Liferay Platform versions the app is compatible with. Make sure to choose a version of the app that is compatible with your Liferay Platform release.
