There was a little update two days after the 23.04.15 release to fix some small issues. (The version number is always the date of the release in year-month-day format.)
The MEGA download folder has a sub-folder with the old update files: https://mega.nz/folder/CpQXwBDS#wwZlWRrPWoGzZX5h0-MlRQ

It's for the release from 31. March, which is the number on the right in the file name, and updates it to the version from the 17th April. After that, you can use the newest update files to get to the most recent version, 23.05.06.
