Emacs Version Numbers

This are some notes based on my observations.

  • X.0.Y are alpha/beta stage. When Y is 90 or above they are "pretest". Usually very stable
  • I have only seen Y at 50 and 90, 91, 92. But I assume they slowly increment them.
  • X.1 is the first stable release
  • There are usually rc for every minor version except 0; sometimes many.
