v2.3.10

Added

• You can now sponsor PrintGuard. Apple charges $99 a year for the Developer Program, and
  without it the macOS desktop app cannot be signed or notarised, which is why macOS calls it
  an unidentified developer the first time you open it. Sponsorship goes towards that licence
  first, and nothing in PrintGuard is locked behind it. Nothing else changed in this release,
  so there is nothing to gain by updating from 2.3.9.
