Psychopy version

dear friends, where can we download psychopy version of 1.82.01 and 1.84.2?

Old releases can be found at Releases · psychopy/psychopy · GitHub

1.84.2 can be found on page 9 (at least today). Expand the assets and you probably want the win32.exe file or the OSX file (the other files are the source code that you do not need).
