Dota 2 developers are making a major change to how they update the game. Rather than releasing massive updates twice a year, they will instead be adding things in smaller bite-sized chunks every two weeks. These updates will always happen on a Thursday and will be on a trial-run period for the next six months. At that point in time the Dota 2 developers plan to reevaluate how the every two week updates have been received.
This certainly makes it seem like the developers will be paying close attention to how fans react to the every two week updates. If it turns out everyone hates them and wants to go back to the twice yearly mega updates, they might consider that. I can only imagine that if the team decides the fortnightly updates are too much stress on the team, they'll go back to the previous update schedule.
At the least these more frequent and smaller updates to Dota 2 should allow fans to better digest major changes. Rather than having to completely re-learn the game seemingly from scratch, Dota 2 players will be able to go over major changes and readjust their playing style from there (hopefully) rather quickly. Another big change Dota 2 is making is adding a notification system in-game that will tell you when a change has been made to a hero within your match. That way, if you haven't gotten a chance to check out the patch notes, you'll still know if a change will be affecting you.
It seems the team has very thoughtfully considered this change, and we'll have to see how it works out from here.
