Hello,
After more than one year of design, discussion, vote, iteration, and months of legal work, I’m happy to announce that the logo of MediaWiki has been officially changed. This applies to both the software and logo of https://mediawiki.org.

The old logo of MediaWiki was adopted slightly more than fifteen years ago. This logo was featuring the nice concept of a sunflower representing diversity, constant growth and also wilderness.

However, with years, the logo became outdated and we realized that it had several problems, including but not limited to:
Most, virtually all, software products use a simpler and more abstract form following basic logo design guidelines and best-practices to avoid above (and more) issues. For example, docker, kubernetes, Ubuntu, Vue.js, React, Apache Kafka and many more.

You can find the discussion of changing the logo in https://www.mediawiki.org/wiki/Project:Proposal_for_changing_logo_of_MediaWiki,_2020 . As you can see on this page, a lot of interesting practical and theoretical exchanges happened, leading to the final vote and decision.

The new logo represents a collection of projects built on our engine: each petal is one of the many wikis that we support, and the lack of an explicit core shows that we are part of these projects, as well as and they are part of MediaWiki. The new logo also reflects the fact that evolution never stops, and like the petals of a flower, the development of each project, the growth of each community built on our engine allows everyone else to grow.

The designer of the new logo is [[User:Serhio Magpie]]. With the nice abstraction baked-in, you can use it in large or small sizes or you can adapt it for different usecases (there’s one already for mediawiki on docker: https://phabricator.wikimedia.org/T274678). There is a logo guideline for MediaWiki now: https://www.mediawiki.org/wiki/Manual:MediaWiki_logo_guidelines

We already deployed changes to mediawiki.org and landed related patches on master, meaning from 1.36 release onwards, it’ll come with the new logo. You can follow the work of rolling it out in https://phabricator.wikimedia.org/T268230.

I humbly ask Wikimedians to update their wikis, for example usages on the main pages, Wikipedia articles, templates, and more. You can use the logos in this category on Commons. The files are already protected against upload vandalism. https://commons.wikimedia.org/wiki/Category:MediaWiki_logo_(2020)

A big thank you to all who helped this project to finish. From designers, community members, people who voted and discussed it intensively for months, Wikimedia Legal for doing all the necessary work for transferring the rights, clearing it and filing it for trademark. And many many more people.  

Best
