Bug Fixes

• http1: fix preserving header case without enabling ffi (#​2820) (6a35c175)
• server: don't add implicit content-length to HEAD responses (#​2836) (67b73138)

Features

• server:
  • add Connection::http2_max_header_list_size option (#​2828) (a32658c1, closes #​2826)
  • add AddrStream::local_addr() (#​2816) (ffbf610b, closes #​2773)

Breaking Changes

• ffi (unstable):
  • hyper_clientconn_options_new no longer sets the http1_preserve_header_case connection option by default.
    Users should now call hyper_clientconn_options_set_preserve_header_case if they desire that functionality. (78de8914)

@Turbo87 I cannot merge PRs even though I have the write access, is this intentional?

[Turbo87]

@JohnTitor nope, you should have merge access.

@pietroalbini any idea what might be wrong?
