• http2.Http2ServerResponse.write with array input does not cause an error. test:parallel/test-http-res-write-after-end.js
• http2.Http2ServerResponse.end with array input does not cause an error. test:parallel/test-http-res-write-after-end.js
• http2.Http2ServerResponse's error code start with 'ERR_HTTP2'. test:parallel/test-http-response-add-header-after-sent.js,parallel/test-http-response-remove-header-after-sent.js,parallel/test-http-response-statuscode.js,parallel/test-http-write-head.js
• http2.Http2ServerResponse.setHeader and http2.Http2ServerResponse.writeHead with multiple value of 'content-length' causes an error. test:parallel/test-http-response-multi-content-length.js

Other exposed issues

• http2.connect with http does pass options to net.connect. test:parallel/test-http-localaddress.js related issue
• Call socket.destroy while sending data cause a segmentation fault.(Only with WSL) test:test/parallel/test-https-close.js
• http2.Http2Server does not have server.maxHeadersCount. test:parallel/test-http-max-headers-count.js

Protcol Level Difference

• http2 semicoloned headers *

• http2 does not support '100-continue'

• http1 Connect Method

  • http2 support it by :connect header

• No Content-Length with body

• Host header replaced by :authority

  • https://http2.github.io/http2-spec/#HttpRequest

• 'Connection' Header has no efect with http2

• Upgrade to the websocket
