Symfony 2021 Year in Review
2021 was an incredibly hard year for many people and companies. The Symfony
community was no exception and our thoughts are with all of you who suffered
because of the COVID-19 pandemic. Luckily, thanks to your help and support,
there were some reasons for optimism throughout the year. This blog post highlights
the main Symfony achievements during 2021.
We released three new major versions: Symfony 5.3
in May and Symfony 5.4 (LTS) and
Symfony 6.0 in November. We
also published 63 maintenance versions in seven different branches (3.4, 4.4,
5.1, 5.2, 5.3, 5.4 and 6.0).

According to GitHub contribution stats
these were the most active contributors in 2021 in the main Symfony repositories:
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!
In September 2021 we announced a new Symfony Sponsorship Program
that allows companies to sponsor different parts of the Symfony project, such as
a full Symfony release or a Symfony component.
A few weeks later we announced another
Symfony Sponsoring Program for SaaS Providers
that allows SaaS companies like Amazon, Slack and Twilio to sponsor the packages
that integrate their services into Symfony.
Many companies have already joined the program. Talk to your company about this
and, if you are interested, contact us
to learn more about the program.
We appointed five new members to the CARE Team
which is in charge of enforcing the Symfony Code of Conduct on all official channels
(conferences, websites, GitHub, Slack chat, etc.);
We updated the Symfony Book to Symfony 5.2 version
and we published new translations for it
(13 in total);
We tested the use of GitHub Discussions for Symfony Support;
We improved Symfony Flex
to open source it and to turn it into a serverless application based on GitHub;
We redesigned Symfony Docs website;
We released Symfony UX 2.0 & Stimulus 3 Support;
We launched Symfony Demo 2.0 with Symfony 6.0 support;
We introduced a new feature to automatically create, manage and run the Docker containers
in Symfony applications.
Despite the continuous challenges caused 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!
