Kismac Releases New Version
The Wi-Fi sniffing and monitoring software gets revised to version 0.21a: This is the first stable new release in over a year following the heels of new maintainers of the open-source software project. Development has been ongoing, but it's taken a while to get a version that the programmers feel is ready for broader use.
The new version is a universal binary and supports Intel iMacs, but still lags in the code necessary for the slightly different Wi-Fi chips found in the MacBook Pro and Intel Mac minis. (The iMacs use chips from Broadcom, which hasn't open-sourced its driver code; the other machines use Atheros chips, which should do provide some details on accessing their lower-level functions.)
