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.

One of the most important parts of the Mattermost source code is the one responsible for accessing the Mattermost database: the store. Every single database access is handled by the store, so we needed to find a way to extend its functionality while introducing as little complexity as possible. This is the reason behind the current layered approach using struct embedding.

Lately we’ve been working on improving different parts of the Mattermost server, including our monitoring and observability capabilities. We’ve been using Prometheus and Grafana to monitor our cluster for a while now, and you can read this great post where my colleague Stylianos explains how we have them working for our multi-cluster environment.

Today marks five years since the start of the Mattermost open source project! We reflected on this exciting journey and reminisced about our missteps along the way. We’ve had many laughs and wanted to share them with our community.

Frequent logouts are a frustrating experience for users, especially on servers with short session lengths configured. In v5.24 and later, you can enable the configuration setting for extending session length with activity to automatically extend sessions and keep users logged in as long as they are active in their Mattermost apps.

New feature release offers tighter integration with Office 365 and Active Directory and an improved end-user search and session experience. Mattermost Release v5.24 is generally available today. The new feature release offers tighter integration with enterprise tools such as Office 365 and Active Directory and an improved end-user experience for search and session management.

Many Mattermost DevOps teams work in “Microsoft Shops”—organizations that use Office 365 apps with the Microsoft 365 business plan—and want to tightly integrate with Microsoft tools to more easily collaborate with the rest of the company. Mattermost E20 was architected from the ground up to be highly flexible. As such, integrating with other platforms including Microsoft is easy. Here’s how.

In Linux, system calls (syscalls) are at the heart of everything. They are the primary interface through which an application interacts with the kernel. Therefore, it is vital that they are fast. And especially in a post-Spectre/Meltdown world, this is all the more important.

Recently, a colleague of mine joked that she manages a marketing team of three: Claire, Mark, and Sally. The punchline is that she’s referring to Clearbit, Marketo, and Salesforce. She felt that way because they each have their own role with unique insights and jobs, and her team shares information with everyone else the same way she does through chat.
