The new features are all available in the new AdWords interface.
Google made a few announcements for AdWords advertisers just in time, before Black Friday kicks off the holiday shopping season in the US next week.
About a year ago, Google started testing promotion extensions in text ads. That beta extended to the new AdWords interface this summer. Now, they are rolling out globally in all supported AdWords languages and currencies in the new AdWords interface (aka the new AdWords experience). Promotion extensions let advertisers display specific offers in their text ads without having to create new ads. They can include a percentage off, a promotion code and offer period.
