Ciao a tutti! Mattermost now offers Italian language support, helping 85 million Italian speakers feel more at home on our platform. Additionally, Mattermost 4.0 now has:

Our theme for the Mattermost 4 series is “Integration”. Today, there are over 80 open source projects built on Mattermost and we want to help grow that community wildly fast.

Thanks for all community contributions and in particular to our 4.0 MVPs prixone and sousapro who have made a huge impact in building a community in the Mattermost forums.

Mattermost 4.0 is now available for download. Since it includes security updates, upgrading is recommended. Check out all that’s included:

  • Faster load times thanks to lower bandwidth requirements
  • Greater stability on weak network connections
  • High responsiveness from new native controls
  • Continuous improvement with a move to monthly releases

New Mattermost API v4 and Integrations Directory

A big advantage of Mattermost compared with closed source messaging platforms is that it integrates with existing apps and workflows through integrations developed by the open source community.

To make the Mattermost API web service more accessible and to offer more powerful options enabling a new generation of integrations, we are releasing Mattermost API v4. Highlights include:

  • Fully documented API endpoints
  • More in-depth access to server functionality
  • Wider use of established HTTP verbs
  • Consistent endpoint structures
  • A new and improved Go driver

We’ve also made it easier to find more than 80 open-source third-party apps with an Integrations DirectoryIf you’ve built an integration and are ready to share it with the community, please let us know!

API v3 is now in maintenance mode and will be removed on January 16, 2018. Find tips on migrating from API v3 to API v4 here.

Italian Language Support

Cari saluti ai nostri lettori italiani! We’ve added another hugely important language to Mattermost. There are 66 million Italian speakers in the world and we want the best workplace messaging platform to be available in their native tongue.

That brings the total number of languages supported by Mattermost to 14: English, German, French, Spanish, Chinese (Traditional and Simplified), Korean, Japanese, Dutch, Portuguese, Russian, Polish, Turkish and now Italian.

Thanks to the dozens of contributors who helped make the Italian release possible, in particular Ema Panz and Michael Longo.

More than a dozen other language translations are currently in progress, including NorwegianIndonesian and Swedish. If you’d like to help, or volunteer to translate a new language, please join the Mattermost localization channel to meet the community and get started.

A special thanks also to our localization leads, in no particular order: aeomin (Simplified Chinese), Archie Roller (Russian), Carlos Panato (Portuguese), Christian Arnold (German), Elias Nahum (Spanish), Ema Panz (Italian), Kaya Zeren (Turkish), Michael Longo (Italian), Robert (Polish), Rodrigo Corsi (Portuguese), Ryo Onodera (Japanese), Tim Estermann (German), Tze-Kei Lee (Traditional Chinese), William Gathoye (French), and Yusuke Nemoto (Japanese).

 Enterprise E20: High Availability Upgrades

Mattermost 4.0 launches a new High Availability (HA) configuration that dynamically adds or removes nodes from the cluster making it easier to set up and maintain a cluster environment.

Servers are dynamically added or removed based on discovery and their cluster name using the hashicorp memberlist. When a server starts up it attempts to discover other servers in its cluster. When it shuts down, it leaves the cluster via a gossip command that lets the other servers know it has left.

Consequently you don’t have to modify each config.json to add the new server to the node cluster. You just have make sure that its config.json is identical to the others, and add it to NGINX config. No server restarts are required in that case. To learn more, see our documentation.

Community Integrations

Once again we are indebted to the broad Mattermost community for a significant number of integrations, making the V4.0 release even more exciting. If you’ve built one, or are working on one, please join our community channel for installers or community channel for integrations and apps hosted in our nightly builds server. We’d love to meet you and discuss your work.

When you’re ready to share it, please let us know!

Here are some of the top projects this month:

Python Driver Graphic

A new driver is available to support Mattermost APIv4 integrations written in Python. You can find the repository here and documentation here. Thanks to Christian Vaelor for this integration.

The Bug Genie is a popular issue tracker, a great open source alternative to JIRA. It allows commits to update issues and provides friendly issue tracking support (burndown graphs, charts and estimation tools without additional plugins) for Scrum, Kanban and other agile processes.

Thanks to this integration by Shoreless Consulting you can now automatically post information from The Bug Genie to Mattermost.

Errbot Backend Graphic

APIv4 backend support is now available for the Errbot chatbot thanks to another great integration from Christian Vaelor.

If you would like to monitor GPU usage for a system sending messages via webhooks you might like to try out this new tool from Marco Harrendorf.
