For version 1.1.0, that's \f(CW\*(C`0x10100000L\*(C'\fR. .Sp Any version number may be given, but these numbers are the current known major deprecation points, making them the most meaningful: .RS 4 .ie n .IP """0x00908000L"" (version 0.9.8)" 4 .el .IP "\f(CW0x00908000L\fR (version 0.9.8)" 4 .IX Item "0x00908000L (version 0.9.8)" .PD 0 .ie n .IP """0x10000000L"" (version 1.0.0)" 4 .el .IP "\f(CW0x10000000L\fR (version 1.0.0)" 4 .IX Item "0x10000000L (version 1.0.0)" .ie n .IP """0x10100000L"" (version 1.1.0)" 4 .el .IP "\f(CW0x10100000L\fR (version 1.1.0)" 4 .IX Item "0x10100000L (version 1.1.0)" .RE .RS 4 .PD .Sp For convenience, higher numbers are accepted as well, as long as feasible. For example, \f(CW\*(C`0x60000000L\*(C'\fR will work as expected. However, it is recommended to start using the second form instead: .RE .ie n .IP """mmnnpp""" 4 .el .IP \f(CWmmnnpp\fR 4 .IX Item "mmnnpp" This form is a simple decimal number calculated with this formula: .Sp \&\fImajor\fR * 10000 + \fIminor\fR * 100 + \fIpatch\fR .Sp where \fImajor\fR, \fIminor\fR and \fIpatch\fR are the desired major, minor and patch components of the version number. For example: .RS 4 .IP "30000 corresponds to version 3.0.0" 4 .IX Item "30000 corresponds to version 3.0.0" .PD 0 .IP "10002 corresponds to version 1.0.2" 4 .IX Item "10002 corresponds to version 1.0.2" .IP "420101 corresponds to version 42.1.1" 4 .IX Item "420101 corresponds to version 42.1.1" .RE .RS 4 .RE .RE .RS 4 .PD .Sp If \fBOPENSSL_API_COMPAT\fR is undefined, this default value is used in its place: \&\f(CW30300\fR .RE .IP \fBOPENSSL_NO_DEPRECATED\fR 4 .IX Item "OPENSSL_NO_DEPRECATED" If this macro is defined, all deprecated public symbols in all OpenSSL versions up to and including the version given by \fBOPENSSL_API_COMPAT\fR (or the default value given above, when \fBOPENSSL_API_COMPAT\fR isn't defined) will be hidden. .SH COPYRIGHT .IX Header "COPYRIGHT" Copyright 2018\-2021 The OpenSSL Project Authors.
