This release includes the following bugfixes:
.IP "-1, --tlsv1"
(SSL)
Forces curl to use TLS version 1.x when negotiating with a remote TLS server.
-You can use options \fI--tlsv1.0\fP, \fI--tlsv1.1\fP, and \fI--tlsv1.2\fP to
-control the TLS version more precisely (if the SSL backend in use supports such
-a level of control).

+in use supports such a level of control).
.IP "-2, --sslv2"
(SSL) Forces curl to use SSL version 2 when negotiating with a remote SSL
server. Sometimes curl is built without SSLv2 support. SSLv2 is widely
(SSL)
Forces curl to use TLS version 1.2 when negotiating with a remote TLS server.

+.IP "--tlsv1.3"
+(SSL)
+Forces curl to use TLS version 1.3 when negotiating with a remote TLS server.
+(Added in 7.51.1)
.IP "--tr-encoding"
(HTTP) Request a compressed Transfer-Encoding response using one of the
algorithms curl supports, and uncompress the data while receiving it.
