YAML code blocks not rendered in Changelog

[FlorianHockmann]

YAML code blocks seem to be missing in the Changelog.

The changelog.md contains this:

If you want to use GraphBinary, you have to add following to the gremlin-server.yaml after the keyword serializers. This will add the support on the server site.

    - { className: org.apache.tinkerpop.gremlin.driver.ser.GraphBinaryMessageSerializerV1, 
        config: { ioRegistries: [org.janusgraph.graphdb.tinkerpop.JanusGraphIoRegistry] }}
    - { className: org.apache.tinkerpop.gremlin.driver.ser.GraphBinaryMessageSerializerV1, 
        config: { serializeResultToString: true }}

But I don't see the YAML in the rendered page: https://docs.janusgraph.org/changelog/#graphbinary-is-now-supported

This however seems to be limited to the Changelog. YAML code blocks are rendered correctly in the rest of the docs, e.g., here: https://docs.janusgraph.org/configs/#janusgraph-server
