Steam's autumn sale will run from 7am on November 26 to 7am on December 2 (all NZT), but it won’t feature any flash sales or daily deals.

The dates initially showed up courtesy of a Steamworks developer group post that made it on to Reddit:

In past sale events, we’ve asked for two discounts—a duration discount that runs for the length of the sale, and a feature discount that runs in the event that a game is featured on the front page. This year, to optimize the sale for customers and to allow us to feature and recommend your products in more ways to more customers, we’re asking for just one discount, to run the length of the sale.

We’ll still be highlighting top games on the front page for 24-48 hour spans, but those products will stay at their most competitive discount, before and after being featured. It’s not a major change, but it does make the sale a lot more valuable for customers, and it allows us to build sale tools that highlight and recommend products all sale long, instead of just during front page features.

The veracity of both claims has since been confirmed by Eurogamer, who received word from Valve via the above notice it sent to Steam developers and publishers.

The notice continues:

For a brand new release, if you can't get approval for your best discount for the full length of the sale, that's OK and we can work on a plan for that game. But the vast majority of your catalog should be running its best discount for the duration of the sale.
