RubyInstaller-2.5.3-1 and RubyInstaller-2.4.5-1 are released. These are maintenance releases with bug and security fixes. See ruby-2.4.5 release notes and ruby-2.5.2 release notes. Bundled OpenSSL versions are updated to 1.0.2p and 1.1.1.
The installer executables are now signed with a Microsoft trusted certificate of “Open Source Developer Lars Kanis”. This should give some confidence about the downloaded files and should soften the disposition of anti virus products.
