CHANGES (p.h2-async.0.8.0.doc.CHANGES)

h2: client / server: execute request/response body reads as data frames arrive (#130)
h2: client / server: only give back flow control tokens after surfacing reads to the application (#131)
h2: Set a default of 128MiB for the initial receiving window size (#132)
h2: don't attempt to write frames to an encoder that has closed (#134)
h2: Handle frame size errors in a more robust manner when parsing (#133)
h2: Create push streams with the right priority (as per RFC7540§5.3.5, pushed streams initially depend on their associated stream) (#136)

h2-lwt: Close the communication channel after shutting down the client (#108)
h2-lwt-unix: fix premature SSL termination in the SSL / TLS runtimes (#109)
h2-lwt-unix: TLS runtime: adapt to TLS v0.11.0 (#109)
h2-lwt-unix: feed EOF to the state machine if the socket has been closed -- this is especially important on the client because it allows connections to terminate cleanly. (#112)
h2: Refactor the Settings module API (#113)
h2-lwt, h2-lwt-unix: Use gluten to implement the Lwt-based runtimes (#114)
h2: set a lower bound on Angstrom 0.14.0 (#118)
h2: in the client implementation, don't report an error if the server has sent an RST_STREAM frame after sending a complete response (#119).
h2-lwt-unix: fix a regression that prevented the SSL / TLS runtimes to negotiate an HTTP/2 connection over the ALPN extension of TLS, in their default implementations (#122)

h2, h2-lwt, h2-lwt-unix, h2-mirage: Remove support for versions of OCaml lower than 4.06 (#74)
h2: Expose more information in client error handlers when initiating a connection (#80)
h2: Make H2.Status.t a strict superset of Httpaf.Status.t (#83)
h2-lwt, h2-lwt-unix: split HTTPS functions in 2: one that sets up a default secure connection and performs the TLS handshake / accept, and one that is more "raw", i.e. leaves that responsibility to the caller. Also exposes the socket type to make it easier to abstract over HTTP / HTTPS (#84)
h2-lwt, h2-lwt-unix, h2-mirage: Improve the H2_lwt.IO interface, don't require a report_exn function, only a state function that returns the socket state (#85)
h2, h2-lwt, h2-lwt-unix, h2-mirage: Add support for starting HTTP/2 for "http" URIs. Covers section 3.2 of the HTTP/2 specification (#87)
h2: Fix misinterpretation of the spec where h2 would consider a request / response malformed if it had a non-zero content-length header and no DATA frames (#89)
h2: Add Request.body_length and Response.body_length (#90)
h2: Fix a bug that caused DATA frames to be incorrectly chunked when returning a streaming response (#91)
h2: Drain pending bytes after getting a Close report from the runtime (#92)
h2: Report connection errors for unknown frames that exceed the maximum payload size -- they may not be speaking HTTP/2 (#93)

h2-mirage: depend on mirage-conduit instead of conduit-mirage, effectively placing a lower bound of OCaml 4.07 on the next release of h2-mirage (#67)
h2-lwt-unix: replace the dune file (previously written in OCaml) with a (select) form to avoid depending on ocamlfind (#68)
h2-lwt, h2-lwt-unix, h2-mirage: Refactor interface code through common H2_lwt_intf and expose less (internal) types (#65)
h2-lwt, h2-lwt-unix, h2-mirage: Expose Client.is_closed (#65)
h2: Don't count peer max concurrent streams based on what the endpoint receives; the endpoint is responsible for selecting it (#71)
h2: Fix bug in Headers.remove that prevented removing the last header pair (#73)
h2: Fix bug in Headers.replace that prevented replacing the last header pair (#76)
h2-mirage: Adapt to Mirage 3.7 interfaces. h2_mirage now requires conduit-mirage >= 2.0.2 and mirage-flow >= 2.0.0 (#77)

h2-mirage: Provide Server and Client functors that take a Mirage_flow_lwt.S module as an argument (#37)
h2: Fix bug in the client implementation that didn't report connection preface errors as soon as they happened (#38)
h2: optimize the stream scheduler: previously when the writer yielded between writes, a wake up function was registered with all the (active) streams, which required a linear traversal of all the streams. The optimization is to allow every stream to wake up a global writer to which they hold a reference (#40)
h2: improve handling of received frames against closed streams (#40)
h2: in the client implementation, call the stream level error handler when receiving an RST_STREAM frame (#42)
h2-lwt-unix: fail earlier when setting up a SSL/TLS server without the depopts being available (#46)
h2-lwt-unix: improve the default ALPN negotiation mechanism in the SSL binding (#46)

h2: Fix false negative related to receiving trailer headers with CONTINUATION frames (#11)
hpack: Fix bug where trying to add an entry to an HPACK dynamic table with 0 capacity resulted in an out-of-bounds array access (#13, #35)
h2: Add support for the 421 (Misdirected Request) status code as per RFC7540§9.1.2 (#15)
h2, h2-lwt, h2-lwt-unix, h2-mirage: Add an HTTP/2 client implementation (#16)
h2: Remove dependency on the result package (#18)
h2: Track SETTINGS frames that haven't been acknowledged by the peer (#22)
h2: Don't treat CONNECT requests as malformed (#32, #34)
h2: Respect the initial MAX_FRAME_SIZE setting when allocating the underlying buffer for the frame writer (#34)
