Travis CI has not picked up the last two PRs (#6050, #6054), and I'm unable to trigger a build on master.

It looks like other open source projects are also losing support: https://daniel.haxx.se/blog/2021/06/14/bye-bye-travis-ci/

Github Actions seems like an obvious choice for replacement given we're now using Releases for hosting binaries. Any other suggestions?
