What's new in 4.1

The OpenBSD Project maintains a complete list of changes since 4.0 on its Web site. There have been hundreds of small improvements, but here are the highlights:

* spamd enhancements: Greylisting is now enabled by default, and changes have been made to enhance performance.
* Multiple Packet Filter improvements: Many changes have been made to the OpenBSD Packet Filter that enhance its default security, expand the degree to which it can be customized, and improve its logging abilities.
* Initial RIM BlackBerry support: You can now plug in and charge your BlackBerry device through a USB cable connected to an OpenBSD machine. Unfortunately that's all there is to say about OpenBSD's BlackBerry support right now.
