Release History

0.4.0 (2015-06-21)

New Features

  • HTTP/1.1 and HTTP/2 abstraction layer. Don't specify what version you want to use, just automatically get the best version the server supports!
  • Support for upgrading plaintext HTTP/1.1 to plaintext HTTP/2, with thanks to @fredthomsen! (Issue #28)
  • HTTP11Connection and HTTPConnection objects are now both context managers.
  • Added support for ALPN negotiation when using PyOpenSSL. (Issue #31)
  • Added support for user-provided SSLContext objects, with thanks to @jdecuyper! (Issue #8)
  • Better support for HTTP/2 error codes, with thanks to @jdecuyper! (Issue #119)
  • More gracefully close connections, with thanks to @jdecuyper! (Issue #15)

Structural Changes

  • The framing and HPACK layers were stripped out into their own libraries.

Bugfixes

  • Properly verify hostnames when using PyOpenSSL.

0.3.1 (2015-04-03)

Bugfixes

0.3.0 (2015-04-03)

New Features

  • HTTP/1.1 support! See the documentation for more. (Issue #75)
  • Implementation of a HTTPHeaderMap data structure that provides dictionary style lookups while retaining all the semantic information of HTTP headers.

Major Changes

  • Various changes in the HTTP/2 APIs:
    • The getheader, getheaders, gettrailer, and gettrailers methods on the response object have been removed, replaced instead with simple .headers and .trailers properties that contain HTTPHeaderMap structures.
    • Headers and trailers are now bytestrings, rather than unicode strings.
    • An iter_chunked() method was added to repsonse objects that allows iterating over data in units of individual data frames.
    • Changed the name of getresponse() to get_response(), because getresponse() was a terrible name forced upon me by httplib.

0.2.2 (2015-04-03)

Bugfixes

  • Hyper now correctly handles 'never indexed' header fields. (Issue #110)

0.2.1 (2015-03-29)

New Features

  • There is now a hyper command-line client that supports making HTTP/2 requests directly from the command-line.

Major Changes

  • Support for the final drafts of HTTP/2 and HPACK. Updated to offer the 'h2' ALPN token.

Minor Changes

  • We not only remove the Connection header but all headers it refers to.

0.2.0 (2015-02-07)

Major Changes

  • Python 2.7.9 is now fully supported.

0.1.2 (2015-02-07)

Minor Changes

  • We now remove the Connection header if it's given to us, as that header is not valid in HTTP/2.

Bugfixes

  • Adds workaround for HTTPie to make our responses look more like urllib3 responses.

0.1.1 (2015-02-06)

Minor Changes

  • Support for HTTP/2 draft 15, and 16. No drop of support for draft 14.
  • Updated bundled certificate file.

Bugfixes

  • Fixed AttributeError being raised when a PING frame was received, thanks to @t2y. (Issue #79)
  • Fixed bug where large frames could be incorrectly truncated by the buffered socket implementation, thanks to @t2y. (Issue #80)

0.1.0 (2014-08-16)

Regressions and Known Bugs

  • Support for Python 3.3 has been temporarily dropped due to features missing from the Python 3.3 ssl module. PyOpenSSL has been identified as a replacement, but until NPN support is merged it cannot be used. Python 3.3 support will be re-added when a suitable release of PyOpenSSL is shipped.
  • Technically this release also includes support for PyPy and Python 2.7. That support is also blocked behind a suitable PyOpenSSL release.

For more information on these regressions, please see Issue #37.

Major Changes

  • Support for HPACK draft 9.
  • Support for HTTP/2 draft 14.
  • Support for Sever Push, thanks to @alekstorm. (Issue #40)
  • Use a buffered socket to avoid unnecessary syscalls. (Issue #56)
  • If nghttp2 is present, use its HPACK encoder for improved speed and compression efficiency. (Issue #60)
  • Add HTTP20Response.gettrailer() and HTTP20Response.gettrailers(), supporting downloading and examining HTTP trailers. (Discussed in part in Issue #71.)

Bugfixes

  • HTTP20Response objects are context managers. (Issue #24)
  • Pluggable window managers are now correctly informed about the document size. (Issue #26)
  • Header blocks can no longer be corrupted if read in a different order to the one in which they were sent. (Issue #39)
  • Default window manager is now smarter about sending WINDOWUPDATE frames. (Issue #41 and Issue #52)
  • Fixed inverted window sizes. (Issue #27)
  • Correct reply to PING frames. (Issue #48)
  • Made the wheel universal, befitting a pure-Python package. (Issue #46)
  • HPACK encoder correctly encodes header sets with duplicate headers. (Issue #50)

0.0.4 (2014-03-08)

  • Add logic for pluggable objects to manage the flow-control window for both connections and streams.
  • Raise new HPACKDecodingError when we're unable to validly map a Huffman-encoded string.
  • Correctly respect the HPACK EOS character.

0.0.3 (2014-02-26)

  • Use bundled SSL certificates in addition to the OS ones, which have limited platform availability. (Issue #9)
  • Connection objects reset to their basic state when they're closed, enabling them to be reused. Note that they may not be reused if exceptions are thrown when they're in use: you must open a new connection in that situation.
  • Connection objects are now context managers. (Issue #13)
  • The HTTP20Adapter correctly reuses connections.
  • Stop sending WINDOWUPDATE frames with a zero-size window increment.
  • Provide basic functionality for gracelessly closing streams.
  • Exhausted streams are now disposed of. (Issue #14)

0.0.2 (2014-02-20)

  • Implemented logging. (Issue #12)
  • Stopped HTTP/2.0 special headers appearing in the response headers. (Issue #16)
  • HTTP20Connection objects are now context managers. (Issue #13)
  • Response bodies are automatically decompressed. (Issue #20)
  • Provide a requests transport adapter. (Issue #19)
  • Fix the build status indicator. (Issue #22)

0.0.1 (2014-02-11)

  • Initial Release
  • Support for HTTP/2.0 draft 09.
  • Support for HPACK draft 05.
  • Support for HTTP/2.0 flow control.
  • Verifies TLS certificates.
  • Support for streaming uploads.
  • Support for streaming downloads.
