Optimized encoding of animated GIFs

The encoding of animated GIF images has been improved. Now each consecutive frame is analyzed and compared with the previous frame, and only a minimal rectangle containing all changes is encoded subsequently.

This means that, for many animated GIFs, less image information needs to be encoded, resulting in smaller file sizes. In general, this effect also outweighs the additional computation cost for frame comparison, resulting in faster encoding.

CAE character encoding is forced to UTF-8

The recommended way to configure character encoding for request and response of the CAE is to use org.springframework.boot.autoconfigure.web.servlet.HttpEncodingAutoConfiguration . Hence, the default deployment configures spring.http.encoding.force=true to force character encoding of requests and responses to UTF-8.

If the autoconfiguration cannot be used, the property cae.set-unknown-mime-type can be used to control whether or not an instance of com.coremedia.blueprint.cae.filter.UnknownMimetypeCharacterEncodingFilter is registered. The default is false .

Improved Theme Resource Bundle Fallback Mechanism

The fallback mechanism used for theme builds will now also fallback to the master language if there is no explicit resource bundle for the locale of the site the theme is used in.

Before the change an empty resource bundle needed to be added with the "master" link property set to the master resource bundle. This can now be removed.
