Google announced on Google+ they have pushed out an updated version of the AdWords Editor.

This is version 10.3 and the new features include:

Demographic targeting:

View and update your AdWords demographic targeting on the new Gender and Age tabs.
Include demographic targeting in import and export files.
Copy and paste demographic targets and exclusions between ad groups and campaigns.
Learn more about gender targeting and age targeting in the Help Center.

Audience targeting:

When you assign audiences to ad groups, a new set of interest categories is available under “Affinity categories (reach).”

Sitelink improvements:

Sitelinks can include two additional fields: Description line 1 and Description line 2.
View the approval status for sitelinks in the Status column on the Sitelinks tab and in the Approval status column in exported CSV files.
The new sitelink import setting gives you the option to import sitelinks with the same text and different URLs.
All sitelinks are now upgraded, so legacy sitelinks no longer appear in AdWords Editor.
