tl;dr: Flathub has improved tooling to make license compliance easier for developers. Distros should rebuild OS images with updated runtimes from Flathub; app developers should ensure they're using up-to-date runtimes and verify that licenses and copyright notices are properly included.

We have replaced Buildbot with a custom service, and we hope you haven't noticed.

With thousands of apps and billions of downloads, Flathub has a responsibility to help ensure the safety of our millions of active users. We take this responsibility very seriously with a layered, in-depth approach including sandboxing, permissions, transparency, policy, human review, automation, reproducibility, auditability, verification, and user interface.

With apps made for different form factors, it can be hard to find what works for your specific device. For example, we know it can be a bit difficult to find great apps that are actually designed to be used on a mobile phone or tablet. To help solve this, we’re introducing a new collection: On the Go.

There is a storm coming and we are re-architecting our build infrastructure.

It's been a busy year, and our platform and developer community-building efforts are paying off. Let's take a look at what we've been up to over the last six months, and measure its effect.

Starting next week, June 17th, the linter will no longer allow enabling

We're gearing up to launch curated banners on the Flathub home page! However, before we can do that there's one more blocker: Banners need a background color for each app, and many apps don't provide this metadata yet. This is why today we're expanding our MetaInfo quality guidelines and quality checks on the website; If you haven't yet, please add these colors to your app's MetaInfo file using the `` appstream tag, and read on to learn more about brand colors.

Flathub's automatic build validation is more thorough now, and includes checks for issues we previously would have only flagged manually. There is a chance that if your app has been passing the continuous integration checks previously, it will fail now; here's why, and what to do about it.

FOSDEM 2024—a free event for software developers to meet, share ideas, and collaborate—is this coming weekend in Brussels, Belgium and we'll be there! Learn where you can find us or even sit down and discuss Flathub itself, metadata and build validation, upcoming changes, and anything else on your mind.

Earlier this month we shared new app metadata guidelines in response to the growth and maturity of Flathub. Today we're proud to share about that growth in a bit more detail including a huge milestone, how we calculate stats, and what we believe is driving that growth.

Flathub has grown massively over the past few years, making it easier than ever to get a ton of apps all from one place—but with that growth comes new problems. We're here with a solution to ensure developers' apps, Flathub, and the entire Linux desktop ecosystem is presented in what we believe is the best light possible.

You can now find our new documentation at docs.flathub.org or well here, if you're reading this.
