Features

• Daily reminders - the first time you log in to Mattermost each day, get a post letting you know what issues and merge requests need your attention
• Notifications - get a direct message in Mattermost when someone mentions you, requests your review, comments on or modifies one of your merge requests/issues, or assigns you on GitLab
• Sidebar buttons - stay up-to-date with how many reviews, unread messages, assignments and open merge requests you have with buttons in the Mattermost sidebar
• Slash commands - interact with the GitLab plugin using the /gitlab slash command
  • Subscribe to a respository - Use /gitlab subscribe to subscribe a Mattermost channel to receive posts for new merge requests and/or issues in a GitLab repository
  • Get to do items - Use /gitlab todo to get an ephemeral message with items to do in GitLab
  • Update settings - Use /gitlab settings to update your settings for the plugin
  • And more! - Run /gitlab help to see what else the slash command can do
• Supports GitLab On Premise - Works with SaaS and On Premise versions of GitLab
