We released nghttp2 v1.14.1.
In this release, we fixed the bug which causes GOAWAY race with new incoming stream on server side. The bug has been reported in GH-681. This is a regression introduced in 16c4611. We were happy with that commit since nghttp2 server passed all strict mode h2spec tests. However, it turned out that it could not handle some cases well, and one of them is GOAWAY race on server side. We reverted part of that commit to fix this issue. This bug only affects nghttp2 server side session. The client side nghttp2 session is not affected by this bug.
