Bro 2.6 release

Bro v2.6 is now released and available for download:

The most significant change to be aware of is that Bro has
switched to using the new Broker communication library. As a
result, user-written scripts related to cluster operation or
remote communication that worked in previous versions may
require porting to new APIs.

Please read the release notes carefully for helpful porting tips
or other changes relevant to the upgrade process:

Also note that the Bro project is in the process of being
renamed to Zeek, however, the software distribution for this
release is still named Bro. There's not yet been any related
naming changes that alter usage for any provided tools or APIs.

Woo! Always an exciting day.
