list-upgrades - list all available upgrades
Introduction
This command lists all packages that have upgrades available within the
current preferred_state or the installed package's stability,
whichever is less stable. This command does not list releases that are
incompatible with the current PHP version.
If package X is installed with version 0.3.0,
stability alpha, and preferred_state
is stable, Pyrus will list the newest version available
that satisfies stability of alpha, beta
or stable. If package Y is also
installed, with version 1.2.3, stability stable,
only the latest stable release will be listed. In both cases, if the latest
available version that satisfies these requirements is not found, none will
be listed.
Another example: If package X is installed with version
1.0.0, stability stable, and the
preferred_state is alpha, Pyrus
will list the newest version available
that satisfies stability of alpha, beta
or stable.
