Dear Wikibase Community, 

We’re thrilled to announce the release of WMDE.19, our security release compatible with MediaWiki 1.40.3. WMDE.18, our security releases compatible with MediaWiki 1.39.7, will be coming shortly.

Previous changes in the 1.40-based releases:

Please also note that, as always, the file LocalSettings.php is world-readable. Viewing it from within the container reveals the database password and secret key. 

Upgrading your Wikibase

Please note that starting with Wikibase 1.39 release, the Wikibase extension must be enabled in MediaWiki using the Extension Registration mechanism. If you have been providing your own MediaWiki configuration file (LocalSettings.php) for your Wikibase container, make sure to check these upgrade instructions.
