OSS Highlights of November - December 2021

Like the previous OSS highlights, I'll give an overview of OSS work I did in November and December of 2021. I'd like to emphasize that I can do this work because of sponsoring via:

for which I'm very grateful. I love helping peoeple by providing OSS software and this is now my main activity.

Enterprise support

I'd like to add that I'm also offering enterprise support for my OSS projects. It might be good to know there are options beyond sponsoring if your company needs an extra level of support for my OSS libraries. Recurring sponsors are eligible for a discount. Feel free to reach out via Twitter DM, e-mail or on Clojurians Slack to discuss options.

Do you need help with #clojure #graalvm compilation, #clojure static analysis/linting tools, or anything related to my #oss projects? I'm available for USD 150/hr. I also do custom license/support contracts if @github sponsors doesn't fit your business.#cljkondo #babashka #sci

Special thanks to new contributor @mknoszlig who has been quite active in adding new linters in collaboration with me.
