curl 8.10.0 defaults to directory names or 'curl_response' when the -O flag encounters URLs without filenames
↗
curl 8.10.0 changes the -O flag behavior to generate a local filename from the right-most directory path or a default string instead of failing when a URL lacks a filename part.
Scripts using curl -O will no longer error out on path-only URLs, but they will silently create files named curl_response or with directory names instead of failing. This changes the exit code behavior for those URLs from an error to a success, which could mask issues in pipelines that relied on the previous failure. Operators should verify if existing workflows depend on the error condition to catch malformed URLs.

The -O flag previously returned an error when a URL lacked a filename part, but now it falls back to alternative naming strategies.
curl uses the right-most directory name from the URL if available, or the extension-less string curl_response if no path exists.
The --no-clobber flag can prevent curl from overwriting existing files that share the newly generated default names.
