Initially, this logo was displayed for one day, on April 23, 2017, in a period between 12:25pm and 11:30pm (according to MSK+2), at which it would be reverted to the 2015 logo. This was shown just as an on-screen bug.
On its April 23 appearance, this logo was chosen to appear through voting. It was returned, but permanently, on July 30, 2017.
