Mattermost 5.13: Community plugins, DevOps integrations, Series B announcement, and more

Mattermost 5.13 ships with several platform and mobile improvements designed to help your team work better together. Try these new features by downloading Mattermost 5.13 today. Since it includes security updates, upgrading is recommended.

Here’s what else is new this month:

  • DevOps integrations – accelerate workflows with our new DevOps Integration Set, which features a powerful suite of integrations that enable developers to work more productively inside Mattermost using their favorite tools 
  • Community plugins – get more out of Mattermost with several new community integrations, including plugins for GitLab and Jenkins
  • Series B funding – learn more about our $50 million Series B round led by Y Combinator Continuity
  • End of IE11 support – install our desktop apps or migrate to a new browser if you run Mattermost on Internet Explorer, as support for IE11 will be dropped with Mattermost 5.16, which ships in October

Thanks for all community contributions this month and in particular our 5.13 MVP, Adrian Mönnich (ThiefMaster), who contributed several bug fixes to this release. This brings his total lifetime contributions to Mattermost up to 13. Thanks so much, Adrian!

Extend Mattermost with new plugins from the community 

Enjoy an even more productive Mattermost experience thanks to three powerful plugins built with help from our community.

1. GitLab

Accelerate GitLab workflows with a new community integration, currently in beta, that brings GitLab notifications and slash commands to Mattermost. Subscribe to notifications, stay up-to-date with reviews, and see the status of your pull requests at a glance right in Mattermost.

Huge thanks to Romain Maneschi and Justin Smestad for their help!

2. Jenkins

Interact with jobs and builds with slash commands thanks to a new Jenkins plugin for Mattermost.

Thanks to Wasim Thabraze for your help on this one!

3. Sed-style replacement command

Find and replace a string in the user’s previous post with the s/ command with this new plugin.

Many thanks to Evan do Carmo for your contribution to the Mattermost project!

Mattermost announces Series B, led by Y Combinator Continuity

In February 2019, Mattermost announced a $20 million Series A round led by Redpoint Ventures, with participation from S28 Capital and Y Combinator. 

Four short months later, we’re thrilled to announce we just closed a $50 million Series B round led by Y Combinator Continuity, with participation from S28 Capital, Redpoint, and new investor Battery Ventures. 

Mattermost is now Y Combinator’s largest Series B investment ever, as well as its largest open source investment to date.

We couldn’t be more excited, and we plan to use these funds to accelerate community expansion and product development in a new and fast-growing segment.

End of support for Internet Explorer 11 coming in October

Mattermost is dropping support for IE11 effective with the release of Mattermost 5.16, which ships on October 16, 2019. Security updates for Mattermost 5.15, which will be the last regular release to offer IE11 support, will continue to be made until December 15, 2019. 

Here’s the reason for the change: IE11 hasn’t kept pace with evolving web standards as other browsers have. To continue improving our Mattermost web app to help our users become more productive, we need to utilize technologies that aren’t supported by IE and never will be.

If your organization or any users in it runs Mattermost on IE11, you need to move to a supported browser (e.g., Chrome, Firefox, Safari, and Edge) or install Mattermost Desktop Apps to prepare for these changes.

If your users run Mattermost on IE11, you need to move to a supported browser (Chrome, Firefox, Safari, or Edge) or install Mattermost Desktop Apps to prepare for this change. Alternatively, your organization can also use the latest Extended Support Release with IE11 support, Mattermost v5.9, which continues to receive security updates and major bug fixes for the length of its lifecycle.
