As of 3 April 2021, wiimpersonator no longer is checking for updates due to a dependency on the now-deprecated Python 2. Past reports are still available.
Note that the first 3 entries were not created on April 15; they were instead generated before Wiimpersonator went public. The first was from March 9th, the second from March 20th, and the third from March 22nd.
In response to the 3.5 update, wiimpersonator was updated to try various configurations on every run. This also allowed the initial Wii U titles to be downloaded 2 days before the console was released, although they could not be decrypted due to a different common key.
