- update to 1.10:
  * Fixed compatibility with OpenSSL 1.1.x (thanks Antoine Amarilli)
  * Fixed a few minor Win32 compatibility bugs.
  * Fixed an error if the TCP connection to the IRC server couldn't be established under 250ms.
  * Fixed a potential deadlock caused by WSAStartup() being called in DllMain()
