Thank You

This decade has been an incredible journey for the Symfony project. And we're ending the decade at the peak of our popularity. The number of project contributors, Symfony developers, projects using Symfony, Symfony components downloads and Symfony conference attendees is still growing after so many years.

There are many reasons for the Symfony success, but we have no doubt about the most important one: you. Thanks for being part of the amazing Symfony community, especially to the thousands of people who have been 10 years or more with us.

Here's to the next decade of Symfony!
