The wolfSSL team is deprecating the following:
- WOLFSSL_TLS13_DRAFT preprocessor macro
- –enable-tls13-draft18 configure option
These components were originally introduced during the TLS 1.3 standardization process to support interoperability with implementations based on Draft 18 of the TLS 1.3 specification. During the multi-year standardization process (2014-2018), multiple draft versions were published before the final RFC 8446 was released in August 2018.
The –enable-tls13-draft18 configure option currently has no functional effect in the codebase and serves no purpose.
The WOLFSSL_TLS13_DRAFT macro, when defined, modifies version number handling in TLS handshakes to use draft-specific version numbers (TLS_DRAFT_MAJOR = 0x7f) instead of the final TLS 1.3 version numbers. This was designed to maintain compatibility with implementations during the transition period which ended long ago.
Maintaining compatibility with obsolete specifications introduces unnecessary complexity. The TLS ecosystem has fully migrated to the TLS 1.3 standard. For these reasons, we are eliminating draft compatibility.
This decision is not yet final. If you think you need these configuration flags to be available, please reach out to us at support@wolfssl.com and let us know.
If you have questions about any of the above, please contact us at facts@wolfssl.com or call us at +1 425 245 8247.
