On behalf of Twisted Matrix Laboratories, I am pleased to announce the release of Twisted 13.1.

Highlights for this release include:

* trial now has an --exitfirst flag which stops the test run after the first error or failure.

* twisted.internet.ssl.CertificateOptions now supports chain certificates.

* twisted.conch.endpoints.SSHCommandClientEndpoint is a new IStreamClientEndpoint which supports connecting a protocol to the stdio of a command running on a remote host via an SSH connection.

* twisted.web.xmlrpc.QueryProtocol now generates valid Authorization headers for long user names and passwords.

* twisted.internet.endpoints.connectProtocol allows connecting to a client endpoint using only a protocol instance, rather than requiring a factory.
