Q320

a) When a PC changes from race to a lineage, what happens to racial feats?

For example if an elf takes elvish accuracy upon level up, and then later becomes a dhampir do they loose or retain their elf only feat? If you were a wood elf, but then became a dhampir, can you take wood elf magic?

b) Are there any changes to racial feat eligibility w/ all the new race rules being published?
