There are a lot of new Advisors.  I also beleive Automatic Memory Management was new in 10g.

The New Features doc is the best place to start:
http://docs.oracle.com/cd/B19306_01/server.102/b14214/chapter1.htm

In that doc be sure to check out: Automatic SQL Tuning.

Regretfully perhaps, but it's time to RTFM as recommended.  Two factoids I found useful were that the CHOOSE hint was dropped as the CBO default; and that STATSPACK was replaced with the automated workload repository (AWR). E-E and Metalink also have tons of previously asked questions about tuning.  HTH

SQL Profiles is a new feature from 10g which is managed by Oracle Enterprise Manager as part of the Automatic SQL Tuning process. Apart from OEM, SQL Profiles can be managed through the DBMS_SQLTUNE package
