Symfony 2020 Year in Review

2020 was a year like no other. The COVID-19 pandemic disrupted the personal and professional lives of millions of people. Symfony was no exception and we struggled at times during this year. Nonetheless, thanks to your help and support, we won through and 2020 was a good year for Symfony, all things considered.


We released two new major versions: Symfony 5.1 in May and Symfony 5.2 in November. We also published 59 maintenance versions in six different branches (3.4, 4.3, 4.4, 5.0, 5.1 and 5.2).

In addition, we published 274 blog posts, including 74 New in Symfony articles explaining the new features introduced by Symfony 5.0, 5.1 and 5.2.

Events and Conferences

We had to cancel most of the physical conferences because of the restrictions imposed by the COVID-19 pandemic, but we could organize the following:

We also organized some online conferences:

Next year, we’ll organize a single physical conference in English: SymfonyCon Disneyland Paris 2021 (December 2-3, 2021). We’ll also organize more online conferences, including several regional conferences in Poland, France, Germany and Spain.

Symfony Core Team

The Symfony Core Team is the group of developers that determine the direction and evolution of the Symfony project.

In 2020, Symfony appointed five new members to the group:

Symfony Components

Symfony components surpassed 500 million downloads in 2016, 1 billion in 2017 and 3 billions in 2019. In 2020 they surpassed 6 billion downloads and our pseudo-real time download stats show around 110 downloads per second (~9.6 million downloads per day).

In 2020 we released three new components:

And we deprecated the Inflector component.

Symfony UX

One of the biggest news for Symfony in 2020 was the new Symfony UX initiative. In short, Symfony UX is the Symfony Flex equivalent for JavaScript: a tool to build amazing User Experiences in the browser as quickly as we can now setup PHP libraries and bundles.


We published four security advisories. Thanks to the Symfony Security Team for their coordination work and thanks to all developers who reported and fixed those vulnerabilities.

Symfony 5 Book

In 2019, a new book about Symfony was announced: Symfony 5: The Fast Track. It was originally launched as a crowdfunding project, and the project backers received it as a printed book.

In 2020 we published the book contents for free in 14 languages thanks to the amazing work of the translation teams.

Symfony Store

In June we finally announced the official Symfony store which sells all kinds of official Symfony swag and ships all over the world.


According to GitHub contribution stats these were the most active contributors in 2020 in the main Symfony repositories:

Symfony Code

  1. Nicolas Grekas: 442 commits
  2. Fabien Potencier: 381 commits
  3. Alexander M. Turek: 144 commits
  4. Christian Flothmann: 138 commits
  5. Jérémy Derussé: 101 commits

Symfony Docs

  2. Wouter De Jong: 108 commits
  3. Oskar Stark: 98 commits
  4. Thomas Landauer: 49 commits
  5. Tobias Nyholm: 46 commits

These are the stats for the two main Symfony repositories, but there are many other contributors working on other repositories and there are many developers working on third-party bundles too. Thanks to all of them!

Despite the challenges introduced by the COVID-19 pandemic, this was a good year for Symfony. All this wouldn’t be possible without your continuous support. Thanks for being part of the Symfony community and stay safe!

Help the Symfony project!

As with any Open-Source project, contributing code or documentation is the most common way to help, but we also have a wide range of sponsoring opportunities.

You mean "Symfony 5.1" ? :)

Good Job !
@volti thanks for the heads up. It's fixed now. Cheers!
Shouldn't it read "two new minor versions"?
Hi @Javier

Great Job :)

I think 5.1 or 5.2 are the mineur version. A major and well 4.0 / 5.0 / 6.0


Great Job :)
