‘guix pull’ updates the versions of packages that are *available* 
(guix package --list-available), but does not update any packages 
currently *installed* on your system.  For example:

  $ guix package --list-available=icecat
  icecat	78.3.0-guix0-preview1	...

  $ guix install icecat

  $ icecat --version
  GNU IceCat 78.3.0esr

  $ guix pull

  $ guix package --list-available=icecat
  icecat	78.4.1-guix0-preview1	...

  $ icecat --version
  GNU IceCat 78.3.0esr

  $ guix upgrade icecat # or guix install icecat

  $ icecat --version
  GNU IceCat 78.4.1esr

Kind regards,
