Hi Everyone,

Curl 8.3.0 is now available on the ITUGLIB website for OpenSSL 3.1.x, 3.0.x, 1.1.1w, and 1.0.2u. Note that OpenSSL 3.1.x DLLs are binary compatible with 3.0.x so you can use either.

Regards,
Randall Becker
On Behalf of the ITUGLIB Technical Committee

Quoted from the Curl 8.3.0 Announcement below:

I'm happy to ship another release. This time there is a single CVE being announced in association with it, so check the follow-up email with details on that.
