"To me, the latest is the latest my OS provides me. If #curl maintainers dont care about pushing the latest into the OSes they support, it's not me to blame. I think curl maintainers should push Centos to provide the latest to all users. What's the purpose of you fixing multiple bugs and security holes if you dont spend time to make it available to the broader audience?"
We are obviously all just too lazy.

How many authors have their contributions in #curl product source code? How many have had their previous work completely removed. Over time.
The first #curl release with code present authored by 200 persons was done in 2015-04-22. In that release, we had already removed all traces of contributions from 20 authors.
In the latest release, 604 authors' code is still present. 171 authors' work have been replaced.

If you use brew’s curl on macOS, are you really using it? I installed and had curl setup a couple of years ago. Today it appears that curl was now pointing to Apple’s version, which has this issue (daniel.haxx.se/blog/2024/03/08…). Looks like brew doesn’t add a symlink for curl to /opt/homebrew/bin. Running `ln -s /opt/homebrew/opt/curl/bin/curl /opt/homebrew/bin` resolved the issue.
