The ultimate goal of writing tests should be improving the user’s in-app experience and increasing developers’ confidence in shipping new or improved apps. The Mattermost team has been continuously writing different types of tests to improve the product. Such extensive automated testing has enabled them to ship a new release—with new features and improvements—every single month for the last few years. Thousands of developers contribute to the codebase.

Nimbella and Mattermost today announced that they are offering a solution that allows any enterprise using Mattermost to easily build and run custom slash commands and apps with enterprise security capabilities.

Mattermost Release v5.26 is generally available today. The new feature release offers enhancements to member and channel management, logs, channel sidebar, help, and the mobile app. The release includes the following new features.

As of October 15, 2020, Mattermost Extended Support Release (ESR) version 5.19 will no longer be supported. If any of your servers are not on ESR 5.25 or later, we highly recommend that you upgrade immediately. With our simple upgrade steps, it takes only a few minutes. Mattermost adopts a monthly tick-tock release cycle, with a new version shipping on the 16th of each month.

A lot will happen over the next 1,000 years, and the codebase for the Mattermost open source project will be along for the entire ride. On July 8, GitHub successfully deposited 21 terabytes of open source repository data in the Arctic World Archive, a (very) long-term storage facility located on the Svalbard archipelago in Norway near the North Pole.

It’s been more than a year-and-a-half since we started using Cypress for our automated functional testing, and it has been well worth the investment. Cypress has now become an essential part of our process to automate regression testing, which helps us ship new releases faster, with increased quality.

One of our favorite things about Mattermost is that it makes it easy for teams to collaborate on projects and topics in specific channels. Today, we’re excited to announce that Mattermost users can now easily carry conversations over to a video conference and screen sharing with Jitsi, a leading open-source video conferencing solution.

Here at Mattermost, our team of developers and quality assurance analysts are proud of what we build and work hard to ship a quality product on the 16th of each month. However, maintaining our high bar for quality month over month isn’t without its challenges!

Mattermost Release v5.25 is generally available today. The new Extended Support Release offers many bug fixes for increased stability (see changelog for details) as well as the following new features.
