Thread:Project:Support desk/How to check compatibility of extensions and MediaWiki version/reply (3)

You're welcome!

Many updates are directly done by those, who introduced a change. E.g. if someone deprecates or removes a MediaWiki API, then he often also updates the extensions, which use this API. However, that does not mean that all extensions necessarily must be compatible directly after a new MW release has been made. In that case it might help to inform the extension author to get things working again.
