尽管8.7在欧服和俄服已经放出，但是显然还有一些问题（可能与一些玩家的卡屏掉帧有关）。因此开发者决定开启8.7三测，下面是一些改动：

Hello everyone,

even though the 8.7 is already out on EU and RU servers, there have been apparently some issues with it (possibly linked to sharp FPS drops for some players). This is why the developers decided to open the third version of the 8.7 test, with following changes:

8.7 Test 3

– some special effects are reworked and optimized
– fixed some objects, that didn’t get destroyed properly in collisions
– some environment models have been fixed and finished
– the notification bug, when your own tank was detracked by a HE shell, has been fixed
– removed the possibility to retrain crews to the T-50-2 tank, that has been removed from the game
– finished the work on the voiceover

The update will be a sort of minipatch/hotfix (17Mb)

There will also be a test of the unified premium account.
