Better explanation of the difference between the file ("CHANGELOG")
and its function "the change log".
Changed
Refer to a "change log" instead of a "CHANGELOG" throughout the site
to differentiate between the file and the purpose of the file — the
logging of changes.
Removed
Remove empty sections from CHANGELOG, they occupy too much space and
create too much noise in the file. People will have to assume that the
missing sections were intentionally left out because they contained no
notable changes.
