Changes in libsoup from 2.2.0 to 2.2.1:

	* Updated for a libgcrypt API change between 1.1.9x and 1.2.x
          that caused a crash at runtime if you compiled against
          1.2.x. [66342]

	* SSL certificate validation failure should now always result
          in a status of SOUP_STATUS_SSL_FAILED, rather than getting
          turned into SOUP_STATUS_IO_ERROR. [64414]

Changes in libsoup from the 2.0 series (1.99.x versions) to 2.2:

	* Most of the libsoup datatypes are now GObjects. (SoupUri
	  is currently an exception to this.)

		* SoupMessage now emits signals at various stages of
	          processing. (Eg, "wrote_body", "got_headers".) (You
	          can also still use soup_message_add_*handler().)

	* SoupContexts are gone; soup_message_new() now takes a URI
	  string.

	* All formerly global state is now maintained by the
          SoupSession object. (This includes the connection pool,
          proxy server, cached authentication information, SSL
          certificates, etc.)

		* You can create a SoupSessionAsync (for 2.0-like
		  behavior) or SoupSessionSync (for blocking,
		  synchronous usage).

		* You can add SoupMessageFilter objects to a session
                  to have certain processing automatically performed
                  on every message sent via that session. (Eg, setting
                  up handlers.)

		* NTLM authentication is no longer supported by
	          default. You must enable it by setting the
		  SOUP_SESSION_USE_NTLM flag on the session.

		* The preferred method of handling authentication is
	          now via the "authenticate" and "reauthenticate"
	          signals on SoupSession. (The old style, of encoding
	          the user and password information into the url is
	          also still supported.)

	* The SOUP_ERROR_* values are now SOUP_STATUS_* (so that we
          don't have "SOUP_ERROR_OK" and the like).

		* SOUP_MESSAGE_IS_ERROR() is gone, since some cases
		  want to include 3xx responses and some don't.

		* SOUP_ERROR_CANT_AUTHENTICATE and
                  SOUP_ERROR_CANT_AUTHENTICATE_PROXY are now gone,
                  since they didn't carry any information that
                  SOUP_STATUS_UNAUTHORIZED and
                  SOUP_STATUS_PROXY_UNAUTHORIZED don't.

		* DNS errors now show up as the new status code
		  SOUP_STATUS_CANT_RESOLVE rather than being mixed in
		  with SOUP_ERROR_CANT_CONNECT.

	* Minimal SOAP support has been added back, via
          SoupSoapMessage/SoupSoapResponse

	* The HTTP I/O state machine was completely rewritten, fixing
	  numerous crashes, leaks, and protocol errors.

	* SoupUri now conforms to RFC 2396. Mostly.

	* Various test programs have been added under tests/

	* Removed:

		* Support for OpenSSL (which was horribly buggy) and
		  Mozilla NSS (which was never finished). We only
		  support GNUTLS for SSL now.

		* SOCKS support

		* CGI support in SoupServer
