Championship clubs are now free to complete transfers and many pieces of business have already been concluded.
There is only a short turnaround for the start of the 2020/21 season, with the competition beginning on September 12 - but the transfer window will remain open for almost another month before closing on October 6.
While it is expected that there will be a reduction in big-money transfers due to the economic impact of the coronavirus pandemic, there is still likely to be millions spent as clubs prepare for the new season.
Here, we have gathered every single piece of business completed so far and we will update this page throughout the summer.
