What's New in 1.0.2 ===================
- Serial port support. - GPS (global positioning system), supporting NMEA 0183 and Rockwell Zodiac devices. - GTK2 event loop. - Improved event scheduling support. - Many new examples, including an example of Cocoa (Mac OS X) integration. - Fancy Win32 installer, with Start menu integration. - Large number of improvements to the SSH server. In addition, Twisted now ships with a command-line ssh client (conch), with same options as openssh client. Also included is a Tk GUI ssh client, that does not require a terminal emulator, and a program for generating ssh keys. - Simplified HTTP client API, for fetching URLs. - Dict protocol implementation (RFC 2229). - Improvements to cReactor, a networking event loop implemented in C. - Lenient mode for microdom, which allows parsing very non-standard HTML, and many improvements to the DOM support. - Trial, a unit testing framework, replaces use of Python's unittest.py. The API is almost identical to Python's. - Google querying support. - Shoutcast protocol support. - Client XML-RPC support. - Many improvements to Twisted's DNS support, both client and server. - Bug fixes, more tests and documentation.
What is Twisted? ================
Twisted is an event-driven framework for building networked clients and servers. It contains a powerful and simple networking core, a full-featured suite of interoperable protocols, among them a powerful web server and applications framework.
Twisted supports many event loops for both server apps and GUI integration on the client side, including:
- Win32 events, including GUI support - GTK+ - GTK+ 2 - Qt - wxPython - Tkinter - Java
Twisted can run protocols over TCP, SSL, UDP, multicast, Unix sockets and subprocesses. It also includes scheduling support, threading integration, RDBMS event loop integration and other basic requirements for networked applications.
Also included are implementations of many protocols. In some cases this includes complete frameworks providing facilities on top of the base protocol:
- SSH - FTP - HTTP, including a complete web framework - XML-RPC - SOAP server framework - NNTP and complete NNTP server framework - SOCKSv4 (server only) - SMTP - IRC - telnet - POP3 - AOL's instant messaging TOC - OSCAR, used by AOL-IM as well as ICQ (client only) - DNS - MouseMan serial mice, and GPS devices - Twisted Perspective Broker, a remote object protocol
