Docker images

• docker pull listmonk/listmonk:latest
• docker pull listmonk/listmonk:v0.8.0-beta

v0.7.0-alpha

This is a major breaking release with a completely rewritten frontend and numerous fixes and improvements. Some of the updates:

• New frontend and UI. Snappier and responsive.
• Bulk of the configuration has moved from the TOML file to a new settings UI.
• Built-in BasicAuth for admin dashboard. The Nginx auth proxy is no longer necessary.
• Fullscreen richtext editor with a new syntax-highlighted HTML editor.
• Support for List-Unsubscribe headers.
• Automatic update check and notification on the dashboard
• Better controls on the bulk importer.

IMPORTANT: BasicAuth Admin authentication is now configurable in config.toml / environment variables. The API endpoints also require authentication. The older Nginx authentication is unnecessary and should be removed. To continue using the old setup (not recommended), leave the admin username and password variables empty.

Upgrading

The configuration file now only has the DB config and a couple other app variables.

Binary

• Download the latest binary.
• Backup the old config file, generate a new config file with ./listmonk --new-config and add the new DB configuration.
• Run ./listmonk --upgrade to upgrade the DB schema and start ./listmonk
• Go to the "Settings" UI on the dashboard and replicate the settings from the old config file. Imporant: Bulk of the config has moved to the settings UI and should be removed from config.toml or from the environment variables. Only retain what is in config.toml.sample and remove everything else.

Docker

• Stop the app container using docker-compose stop app
• Pull the latest version with docker-compose pull. If you are not using :latest tag in your docker-compose.yml then edit the file and set the tag to v0.7.0-alpha.
• Run the DB migrations with docker-compose run --rm app ./listmonk --upgrade.
• Recreate the service with docker-compose up -d app db.
• Go to the "Settings" UI on the dashboard and replicate the settings from the old config file.
