>But that would be the same thing on windows. If you dynamically link your executable to an old version of libcurl and run your executable on a windows with a newer version containing a breaking change, you'll be in trouble, whatever your OS. Most of the time I can run a program from the 1990s on Windows 11 just fine, you can't say the same for Linux. The only incompatibility in Windows that happens frequently is if you try to run a program written for a newer Windows version in an older version. That will likely fail because forwards compatiblity isn't a priority. But with regards to backwards compatiblity, Microsoft goes to herculean efforts to make sure Windows programs written several decades ago will work today.
