These operator functions are now always statically linked into your binaries, even when using the runtime library DLLs. This isn't a breaking change for native or mixed code (/clr), however for code compiled as /clr:pure, this change might cause your code to fail to compile. If you ...

Write the test, either adding to existing test files in/test/unit/or add a new file. (If testing the standard library, put it in the/test/unit/stdlib/subdirectory). Make sure that the test functions have the@testattribute. Run tests and see that they pass. (Recommended settings:c3c com...
Previously nghttp2 did not process client magic (24 bytes byte string). To make it deal with it, we had to use nghttp2_option_set_recv_client_preface(). Since v1.0.0, nghttp2 processes client magic by default and nghttp2_option_set_recv_client_preface() was removed....
