I got notified of a new version of the Tezos client Docker images (via the shell script which accompanies it). But there's no mention of the new version number or changelog.

Where can I read the changelog of the newest version of the Tezos client Docker images?

(I have searched the Tezos Docker repository, gitlab.com/tezos/tezos and the documentation in http://tezos.gitlab.io/master/ to no avail)
