What is this?
Twisted is an event-based framework for internet applications. It
includes a web server, a telnet server, a multiplayer RPG engine, a
generic client and server for remote object access, and APIs for creating
new protocols and services. Twisted supports integration of the Tk or GTK
event loop with it's main event loop. It also has basic support for
running servers on top of jython.
Twisted currently supports the following protocols, all implemented in
pure python, most of them as both servers and clients:
- AOL's instant messaging TOC
- DNS (client only)
- LDAP (client only)
- Echo, discard, chargen and friends
- Perspective Broker

What's new in 0.11.0?
twisted servers can now run using jython, albeit in an inefficient manner.
twisted.names, a DNS system, was checked in. It is still being worked on.
SSL support is now much more robust, and dirdbm works much better as well.
LineReceiver (used by HTTP, SMTP, etc.) limits line length, preventing
DoS attacks. SafeNetstringReceiver serves a similar purpose for netstring
Servers -- especially Web servers or others that open and close
connections frequently -- under high loads should run faster, since
multiple accept() calls are done per select(). Threaded apps might run
faster as well.
Enhanced the twisted.web.widgets API to accomodate multiple deferreds.
Protocol revision in PB, refactoring authentication into simply being an
object one can connect to.
New connection API for PB, simplifying and reducing the number of
potential failure points in the process of writing a PB client.
Much more example code for PB, including some simple examples involving
web.widgets and GTK clients for PB services.
