15## TLS libraries without 1.3 support
16
17curl drops support for TLS libraries without TLS 1.3 capability after May
182025.

20It requires that a curl build using the library should be able to negotiate
21and use TLS 1.3, or else it is not good enough.

23As of May 2024, the libraries that need to get fixed to remain supported after
24May 2025 are: BearSSL and Secure Transport.
