What part(s) of the article would you like to see updated?

In the table presented in the Setting a notice message section, the description for endColumn in the Value column is now:

End column number

It should also explain whether the 1-based column number is inclusive or exclusive, e.g.

End column number, starting at 1. This is exclusive, i.e. the character at the given position
is _not_ considered as part of the text to associate the message with.

Additional information

Here's one example of evidence where a developer seems to have verified that endColumn is exclusive:
