No action is needed by server administrators, and we do not expect resource usage of the Redis instance to change dramatically. + +This release also changes the callback URI for OpenID Connect (OIDC) identity providers. If your server is configured to use single sign-on via an OIDC/OAuth2 IdP, you may need to make configuration changes. Please review [UPGRADE.rst](UPGRADE.rst) for more details on these changes. + +This release also changes escaping of variables in the HTML templates for SSO or email notifications. If you have customised these templates, please review [UPGRADE.rst](UPGRADE.rst) for more details on these changes. + + +Bugfixes +-------- + +- Fix building Docker images for armv7.
