Extend integrations with interactive dialogs

Now you can build even more powerful integrations due to a new feature that enables plugins to trigger interactive dialogs that prompt users to input information. Those inputs are then automatically submitted back to the integration.

Thanks to this functionality, users can open a Jira ticket directly in Mattermost by filling out a simple form, for example.

Increase productivity with new admin commands

Mattermost 5.6 includes more than a dozen new commands that enable admins to manage slash commands, configuration settings, teams and webhooks directly from the command line.

You’ll also notice an improvement to the bulk exporter which makes it easier to migrate data from multiple servers to a single one.

Mattermost now supports the Ukrainian language

At Mattermost, our goal is to improve productivity for organizations around the world.

We’re happy to announce that Mattermost is now available in Ukrainian. Thank you, Lena, for your amazing work!

In other news, Romanian language support, which first appeared in Mattermost 5.2, was promoted out of beta.

With the addition of Ukrainian language support, Mattermost is now available in 16 languages. But we’re not stopping there. Our community is currently working on translating Mattermost into several other languages, including Czech, Serbian, Swedish and more.

If you’re interested in translating Mattermost into a new language, we’d love your help. Please stop by and join the Mattermost localization channel to get started.

Find information faster on desktop

It’s easier than ever to find the information you’re looking for on the Mattermost 4.2 desktop app, which includes a new Ctrl/Cmd+F shortcut that mimics a browser-like search tool.

Some other updates in our desktop app include:

    • Support for the English (UK), Portuguese (BR), Spanish (ES) and Spanish (MX) languages has been added to the spell checker, so teams can worry less about typos
    • Autostart has been enabled by default; new installs will have the desktop app launch when the computer is turned on (this feature can be disabled in the desktop app preferences)
  • A DMG installer has been added for cleaner installs on MacOS

A note on deprecated features

To provide an even stronger Mattermost experience, we’ve also deprecated some features in Mattermost 5.6.

First, support for WebRTC was removed. Mattermost had supported a WebRTC integration (beta) for one-on-one video calling and audio calling.

Why’d we make the change?

We initially included a WebRTC integration as a prototype for community development. Since then, we’ve shifted our focus to open source integrations and plugins. By removing support for WebRTC, we can ensure other video and audio conferencing integrations are stronger.

Currently, Mattermost users have three options for video conferencing:

    • A Zoom plugin, which is installed by default on Mattermost servers

Support for additional web conferencing solutions, including WebEx, is in the works.

Head over to our forum to learn more.

We also removed mobile view support on IE11 due to low usage. Now, we can invest more of our energy in maintaining a high-quality experience on browsers that are more popular with our users.

Both tablet and full view are still available on IE11. If mobile view is needed, we recommended using the desktop app, Chrome, Firefox or Edge. Otherwise, instead of entering mobile view, there will be a horizontal scrollbar after the window shrinks below a certain width.
