Paizo just announced they are changing their process for errata. Instead of waiting to tie the errata to the reprint of the book it was in, they will now release errata twice a year, once in the spring and again in the fall. This will allow them to respond to issues and questions in a more timely manner.
In addition to the announcement, Lead Designer Logan Bonner went over a few of the errata coming out which coincides with the fourth printing of the core rule book.
The biggest change will be with alternate ancestry boosts. This change allows character to choose two free ability boosts from any ancestry. This is to show a wider nuance to the history of the world and characters in it. Players can still use the ancestry's printed options, but now have the option to add more breadth to their character if they choose.
The other big change will be with the alchemist becoming more flexible. With new options coming out in Treasure Vault, this will allow them more flexibility in choosing items for their research field. Alchemists with the chirurgeon field can choose elixirs with healing traits and can substitute their Crafting proficiency rank for anything requiring a proficiency rank in Medicine, including prerequisites. Because they can now choose items that heal HP, there is a ten minute window where characters who gained Hit Points from a perpetual infusion are immune to gaining more Hit Points from subsequent infusions.
Most of the other changes are smaller, like having the soothe spell's wording changed from "1 willing living creature" to "1 willing creature." They did downgrade the gnome flickmace because it was a bit overpowered for a one-handed reach weapon. They reduced its damage, but gave it the sweep trait. A lot of the other errata just clarify where there were two different wordings in the book as to which one was correct or to add in missing information.
