There is a 3rd Suricata Beta available, head on over to http://www.openinfosecfoundation.org/index.php/download-suricata .
Be warned that there is still a few items that need to be fixed.
Here is the list from the download section.
Known issues & missing features We have made significant progress towards reaching our first full (non-beta) release of Suricata. Your feedback is always important to us and we appreciate your time and effort. As always, we are doing our best to make you aware of continuing development and items within the engine that are not yet complete. With this in mind, please notice the list we have included of known items we are working on. - Using the http_cookie keyword seems to cause a match on all packets. - Currently we dont' support the dce option for byte_test and byte_jump. - Stream reassembly is currently only performed for app-layer code. - Inconsistent time stamps in http log file due to handling & updating of the http state. - DCE/RPC over udp is not currently supported. - dce_stub_data does not respect relative modifiers. - Engine does not work properly on big endian platforms. - Time based stats are not calculated correctly.
I don’t see anything that would effect the install procedures, it seems like the dependencies have not changed from I have found.
