Description of issue

This is not as much of an issue as it is a question. When I run, brew update, I sometimes see "New Formulae" and "New Casks" section listed along with "Outdated Formulae" etc. Bellow is an example,

What are the "New Formulae" and "New Casks" sections listing? Are these the new dependencies of the packages to be updated? Or, are these just advertisements for new software added to Brew?

If these are just advertisements, is there anyway to turn these off?

[ZhongRuoyu]

They are the new packages added since you last updated. To turn these off, set the HOMEBREW_NO_UPDATE_REPORT_NEW environment variable to a non-empty value (e.g., 1).

From https://docs.brew.sh/Manpage#environment:

HOMEBREW_NO_UPDATE_REPORT_NEW
If set, brew update will not show the list of newly added formulae/casks.

Okay thank you :)

[lafkpages]

Is there a way to list these manually?

[gabow93]

im also very much in search of this possibility

No, because it's dependent on the changes that happened between updates.
