What happened to the grace period of 5 minutes for editing a post?


1 Answer 1


The comment broke the grace period.

According to ex-CM Shog9's answer,

Edits will be rolled into the previous revision if the previous revision was created by the same author and none of the following conditions are present:

  • The previous revision was created 5 minutes or more in the past
  • A comment has been added to the post after the previous revision by anyone other than the editor
  • An answer has been added to the post after the previous revision (even if the answer was posted by the editor)
  • The previous revision was a rollback
  • The new revision is a rollback
  • [as of April 3rd, 2017] The question was closed after the previous revision.

(Emphasis added)

According to the post's timeline:
