Is there a list or something somewhere that states what rulesets were added into 3.0/ I know some of the SARE rules were added, but not sure which ones.
A partial list was in Daniel Q's 3.0.0 pre1 announcement email. It's not comprehensive, but it's a start.

New rules:
- SPF testing, if the Mail::SPF::Query module is installed.
- added new rules and code to combat Bayes poisoning text and random hash-busters; Habeas rules now verify against the Habeas user list, to combat forged marks used in spam.
- URIDNSBL rules. These do DNSBL lookups on URLs, allowing URLs found in the message body to be used in spam determination. Added the SURBL blocklist (http://www.surbl.org/).
- Spamhaus XBL and a variety of new DNSBL rules
- Hashcash support.
- added Bob Menschel's 'longwords' rules
- added 'backhair' rule, technique based on Jennifer Wheeler's ruleset
- added Matt Kettler's 'antidrug' ruleset
- added anti-fraud rules from Matt Yackley
- added some hostname-based blocklist tests based on the envelope sender address.
- a *lot* of other new rules, too many to detail here
