PlayerUnknown's Battlegrounds has only been out on Steam Early Access since March 23. Since that launch the game has sold over 6 million copies and been updated 14 times. Developer Bluehole has been holding onto a monthly patch schedule with assorted weekly patches in there as well. Apparently that will be changing in the future.
"Today we are changing our patch and update schedule to improve how we work on the game, as well as set realistic expectations for players," Bluehole North American and European partnerships manager Yoon Chang said in a Steam Community post. "Until the official release of the game, we will not have our scheduled weekly or monthly patches rolling out as often as before."
"We’ve found internally that being rushed to finish certain features, and having shorter QA test time between pushing updates caused more issues than it solved in regards to maintaining a high standard of quality. We want to put our best content out, and ensure that everything we do is making the game more enjoyable with every update."
Basically, Bluehole already knows Battlegrounds is a success, so they can ease off the throttle a bit and take their time on releases. This means that Battlegrounds' live servers will theoretically have fewer bugs and issues.
"Although we may not release a weekly patch, we will utilize the test servers for significantly longer periods of time and deploy patches and hotfixes when necessary," added Chang. "This way, when we have a new feature that we’d like to roll-out it will be more thoroughly polished thanks to extensive community feedback. We will still inform our community with public patch notes outlining changes we’ve made with each update. We would like to assure you all that we are still on-track to release our game as per our updated timeline, and we want to emphasize to you that we are not winding down the development."
Battlegrounds has a planned release before the end of 2017's fourth quarter, with a launch on Xbox One in 2018. The developer has a number of features planned for the game prior to that, including two new maps, a weather system, the ability to vault over walls, and potential changes to the current playable map.
