 ## Caveats
 
+### ALPN support
+
 `HTTPS` TLS backend is ruby's own `openssl` gem.
 
 If your requirement is to run requests over HTTP/2 and TLS, make sure you run a version of the gem which compiles OpenSSL 1.0.2 (Ruby 2.3 and higher are guaranteed to).
 
 JRuby's `openssl` is based on Bouncy Castle, which is massively outdated and still doesn't implement ALPN. So HTTP/2 over TLS/ALPN negotiation is off until JRuby figures this out.
+
+### Known bugs
+
+Doesn't work with ruby 2.4.0 for Windows (see [#36](https://gitlab.com/honeyryderchuck/httpx/issues/36)).
