Ray 7cda052bac Release 1.2.3
* dtls/wrapper.py: Add optional parameter to DtlsSocket:
    client_timeout (seconds). If client_timeout is specified,
    clients that have not communicated within the time frame
    will be dropped.
  * setup.py: Version incremented to 1.2.3
  * dtls/__init__.py: Increment version

Ray 0d6ee12121 Release 1.2.2
Produce a Pure Python Wheel instead of a source distribution for Linux.
This speeds up installation and simplifies distribution building.

	* setup.py: Drop support for sdist; add support for bdist_wheel
    without --plat-name switch; persist README.rst; increment version
	* dtls/__init__.py: Increment version

Ray 8ec1dfb56c Installation Fixes and Improvements
Installation as well as distribution generation are now simplified.
With the elimination of MinGW support there is now a unique set of
platform binaries for 32-bit and 64-bit Windows. Pip will now
automatically choose the proper binary wheel or the source
distribution, depending under which platform and Python version it
is being invoked.

	* README.md: add installation section
	* setup.py: rewrite to use bdist_wheel for Windows

    handshaking to 576, suitable for various path MTUs and PPPoE
	* dtls/prebuilt/win32-x86[_64]: Rebuilt with Visual C++ 2008 to
    eliminate requirement to install a C++ redistributable package
	* dtls/prebuilt/mingw-x86: mingw support is deprecated
	* dtls/__init__.py: VERSION introduced
	* setup.py: Version incremented to 1.2.0

Ray 34dc9ca9cd Version rev after fix integration
Increase version to 1.0.1, in preparation for PyPI release. This release
includes a fix by Jayson Vantuyl to an error code import. A proper error
is now emitted when omitting the keyfile on a PyDTLS server.
2014-01-18 20:51:13 -08:00
Ray 7a4919c839 First Stable Release
The version number is incremented to 1.0.0.

Thanks to doneir for reporting that a number of unit test were failing.
This was because two test certificates had expired. This commit replaces
these with updated certificates, along with the tool used for programmatic
certificate generation. The new certificates are set to remain valid for
approximately ten years.
