Outdated warning appears after running brew doctor

[0wnrepo]

• [ yes ] ran brew update and can still reproduce the problem?
• [ this is the issue actually ] ran brew doctor, fixed all issues and can still reproduce the problem? - NO, this is the issue actually.
• [ yes ] ran brew config and brew doctor and included their output with your issue?

What you were trying to do (and why)

Install brew on a new machine / run brew doctor while having Bitdefender installed on macOS 10.14.5 and 10.15.4.
Traffic scan is running ok, the traffic filtering issue was fixed in Bitdefender.

What happened (include command output)

Got a warning that homebrew is incompatible with Bitdefender's Traffic Scan.

Warning: You have installed Bitdefender. The "Traffic Scan" option interferes with
Homebrew's ability to download packages. See:
  https://github.com/Homebrew/brew/issues/5558

Discussed here: #5558

What you expected to happen

Not get a warning, since this is not the case anymore, as it has been fixed.

Warning: You have unlinked kegs in your Cellar.
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
  gettext

Warning: Homebrew's sbin was not found in your PATH but you have installed
formulae that put executables in /usr/local/sbin.
Consider setting the PATH for example like so:
  echo 'set -g fish_user_paths "/usr/local/sbin" $fish_user_paths' >> ~/.config/fish/config.fish

Warning: Your Xcode (10.2.1) is outdated.
Please update to Xcode 11.3.1 (or delete it).
Xcode can be updated from the App Store.
