In this post I'll give updates about open source I worked on during January and February 2024.

To see previous OSS updates, go here.

Sponsors

I'd like to thank all the sponsors and contributors that make this work possible. Like you can read on Bozhidar Batsov's blog these aren't the easiest times for Open Source sponsored software. I have no reason to complain, but I did see a similar drop in sponsoring in the last year. I'm thankful for those who sponsored my projects in the past and even more for those who keep doing so!

Without you, the below projects would not be as mature or wouldn't exist or be maintained at all.

Current top tier sponsors:

• Clojurists Together
• Roam Research
• Nextjournal
• Nubank
