The publishing of TLS 1.3 and DTLS 1.3 obsoleted TLS 1.2 and DTLS 1.2. Note that there are known vulnerabilities in SSL 2.0 and SSL 3.0. In 2021, IETF published RFC 8996 also forbidding negotiation of TLS 1.0, TLS 1.1, and DTLS 1.0 due to known vulnerabilities. NIST SP 800-52 requires support of TLS 1.3 by January 2024.

TLS 1.3 support was subsequently added — but due to compatibility issues for a small number of users, not automatically enabled [50] — to Firefox 52.0, which was released in March 2017. TLS 1.3 was enabled by default in May 2018 with the release of Firefox 60.0. [51] Google Chrome set TLS 1.3 as the default version for a short time in 2017.
[3] [4] [5] HTTP/2 is the first new version of HTTP since HTTP/1.1, which was standardized in RFC 2068 in 1997. The Working Group presented HTTP/2 to the Internet Engineering Steering Group (IESG) for consideration as a Proposed Standard in December 2014, [ 6 ] [ 7 ] and IESG approved it to publish as Proposed Standard on February 17, 2015 (and ...

It is also supported by major web servers over Transport Layer Security (TLS) using an Application-Layer Protocol Negotiation (ALPN) extension [10] where TLS 1.2 or newer is required. [11] [12] HTTP/3, the successor to HTTP/2, was published in 2022. [13]
At that time the dominant Application layer protocols were SSL and TLS 1.1 (TLS 1.2 was only published as an RFC in 2008 [5]), those supported many legacy algorithms and had poor security standards. As Google was in full control over the machines that needed secure transport of RPCs, deployment of systems was relatively easy, and so Google ...
LibreSSL is an open-source implementation of the Transport Layer Security (TLS) protocol. The implementation is named after Secure Sockets Layer (SSL), the deprecated predecessor of TLS, for which support was removed in release 2.3.0.
