Version 1.3.4 is a regular maintenance release, fixing a number of bugs, improving the documentation and providing some more flexibility in the deployment tooling. We're proud to announce the community-contributed Helm charts <https://github.com/open-zaak/charts> for Open Zaak and Open Notificaties, providing an alternative way of deploying both projects on (Haven <https://haven.commonground.nl/>-compliant) Kubernetes clusters. Additionally, we've documented the process on how to deal with security vulnerabilities <https://open-zaak.readthedocs.io/en/stable/support/security.html>;, with support from the Foundation For Public Code. We hope this can serve as a source of inspiration for other Common Ground projects. You can find a complete list of the changes in the release notes <https://open-zaak.readthedocs.io/en/stable/development/changelog.html#id1>;. As always, container images with the appropriate version tags are published on Docker Hub <https://hub.docker.com/r/openzaak/open-zaak>;.
