The hints to find the answer are hidden in the text below. Look carefully.


How do edits work?

Users can edit the questions and answers submitted to the site. This gives the site a wiki feel and allows the information to constantly evolve and remain up to date. Those users who are allowed to edit a post can do so by clicking the edit link associated with that post.

Multiple edits made by the same person may be combined into a single revision, if they occur within a short period of time (currently 5 minutes), unless the post is later edited by someone else or one of the events listed at the bottom occurs. Edits made by the original author are considered part of the base revision if submitted within 5 minutes of posting (again, unless someone else edits the post or one of those events occurs) or migrating. This does not apply if the user doesn't have the remove new user restrictions privilege (awarded at 10 reputation on all sites) - edits from these users will always create a new revision.

It is possible to “rollback” changes made in a revision. This can be done during editing by selecting a previous revision to edit from the dropdown, but can also be accomplished via the "rollback" link displayed on previous revisions within the revision history list. This action will earn you a bronze "Cleanup" badge when first used.

When multiple editors submit binding changes, the last one in “wins”, regardless of who began editing first. Both revisions are preserved however, and changes lost can be restored either by rolling back to the previous revision or by manually copying text into a new revision.

To promote good edits, a user who suggests an edit to someone else’s post will get +2 reputation points when that edit suggestion is approved. You do not get the reputation bonus for binding edits, whether this is because you are editing your own post, you are editing a community wiki post and have the edit community wiki privilege, or you have the edit questions and answers privilege. Also, you are limited to a maximum of 1000 reputation points earned from edits, and reputation earned from suggested edits counts toward the daily reputation limit of 200.

Who may edit a question or answer?

The original author of a question or answer may edit their own post. Additionally, users with the edit questions and answers privilege may edit any question or answer. The one exception is locked posts, which may only be edited by moderators, including the original author, until they are unlocked. Additionally, the amount of reputation needed to edit community wiki posts is much lower than that needed to edit ordinary questions and answers. If a user does not have enough reputation to edit directly, they can still suggest an edit (see a related FAQ question, How do suggested edits work?).

How can you tell what has been changed between edits?

Edit indicator

Once your question has been edited, there will be a note of it, with the time since the last edit hyperlinked to a revision history for the post.

Revision history

Each revision is displayed in a separate, collapsible section. Older revisions start out already collapsed. If a comment was specified by the person editing, that will be displayed in yellow next to the revision number; otherwise, the total number of characters added or removed in that revision will be listed, as well as whether the title and tags have been changed (questions only). Once expanded, the revision will be displayed, with changes highlighted.

The edit link on older revisions lets you copy that edition to a new revision, essentially letting you roll back to that revision and edit it at the same time.

Revision diff color key:

  • Green background: characters added
  • Red text + strikeout: characters removed

  • $\begingroup$ @Lezzup I'm the downvoter. I have enjoyed a lot of your puzzles in the last couple weeks and have upvoted most of them. This one however felt like a lot of pointless legwork chasing a more or less obvious mechanic. And the final solution felt a little too meta and pointless. I don't mean to discourage; you are talented and I look forward to more of your good puzzles. $\endgroup$

Between revisions two and three of this question, a number of characters were added and deleted.
(The latest revisions at the time of writing)

The added characters are:
inthepreviouseditthecharactersinthiscolorarespaces
which can be spaced to read:
in the previous edit the characters in this color are spaces

As these are all the added characters, we can assume that "this color" means green.

The deleted character are:
.yranibnierarolocsihtnisretcarahcddodnaneveeht,tidesuoiverpehtni
which can be spaced and reversed to read:
in the previous edit, the even and odd characters in this color are in binary.

And as these are the deleted characters, assume that "this color" means red.

Now let's look at "the previous edit" (from revision one to revision two).

Treating the added (green) characters as spaces, and noting down the removed (red) letters we have:
tmnbdsxs fmqzpwjz fmotsjvu zygkxibd
bmehgxhc liyvkiul jsmvhuuq ntwjxpzx
bionurly zoqmrnue hjmdjvjt nawvlqaz
zmkwfgpu rwovwqih

Now, treating the "even" letters (b,d,f,...z) as 0, and the "odd" letters (a,c,e,...y) as 1, we can convert those into binary:
01000101 01100100 01101001 01110100
01101001 01101110 01100111 00100000
01101001 01110011 00100000 01100110
01110101 01101110

Now those look suspiciously like ASCII, so let's convert them to get:
Editing is fun
