parents 4914e0e1 cee6e7d9
Pipeline #17168 passed with stage
in 22 minutes and 1 second
o Minor features (compilation):
- Give an error message if trying to build with a version of LibreSSL
known not to work with Tor. (There's an incompatibility with
LibreSSL versions 3.2.1 through 3.4.0 inclusive because of their
incompatibility with OpenSSL 1.1.1's TLSv1.3 APIs.)
Closes ticket 40511.
