Hi everyone,

Fresh from PyCon US, comes a 17.5 prerelease. Fancy things in this release:

- twisted.python.url has been spun out into the new 'hyperlink' package; importing twisted.python.url is now a compatibility alias
- Support for OpenSSL 1.1.0.
- Fixes around the reactor DNS resolver changes in 17.1, solving all known regressions
- Deferred.asFuture and Deferred.fromFuture, to allow you to map asyncio Futures to Twisted Deferreds and vice versa, for use the with Python 3+ asyncioreactor in Twisted
- Support for TLS 1.3 ciphersuites, in advance of a released OpenSSL to enable the protocol
- Further Python 3 support in twisted.web, initial support in twisted.mail.smtp

Please see the NEWS.rst file and download the tarball at https://twistedmatrix.com/Releases/rc/17.5.0rc2/ . (rc1 fell to metadata mishaps!)

Let me know if you notice anything out of the ordinary. If there's no problems, it'll release in the next week or so.

Twisted Regards,

Amber Brown (HawkOwl)
