Clojars Maintenance and Support: November/December 2025 Update

Critical Infrastructure: Clojars Maintentance and Support Update by Toby Crawley

November-December, 2025. Published January 24, 2026

This is an update on the work I’ve done maintaining Clojars in November and December of 2025.
Most of my work on Clojars is reactive, based on issues reported through the community or noticed through monitoring.

If you have any issues or questions about Clojars, you can find me in the #clojars channel on the Clojurians Slack, or you can file an issue on the main Clojars GitHub repository.

You can see the CHANGELOG for notable changes, and see all commits in the clojars-web and infrastructure repositories for this period. I also track my work over the years for Clojurists Together (and, before that, the Software Freedom Conservancy.

Below are some highlights for work done in November and December:

• I did lots of dependency upgrades, based on an antq task I added to the project.
• I fixed a bug where would still try do generate an email for an address in the denylist, which resulted in an NPE and noise in Sentry.
