An extension is a generic term for any kind of distinct addition to CAST AIP which can be downloaded, installed and upgraded separately. An extension usually provides support for:
- technologies/frameworks that are not supported "out-of-the-box" by CAST AIP (for example PHP or EGL)
- methods of extracting and discovering source code stored in specific repositories that are not supported "out-of-the-box" by CAST AIP (for example CVS or Git)
- You can find a list of technologies/frameworks supported by an extension in Covered Technologies. You can also find a full set of documentation for extensions here.
- In an upgrade scenario (i.e. from upgrading from one release of CAST AIP to another) when installing the new release of CAST AIP, there is no need to re-install any extensions you were using with the previous release of CAST AIP.
