=head1 NAME

Test2::API::Breakage - What breaks at what version

=head1 DESCRIPTION

This module provides lists of modules that are broken, or have been broken in
the past, when upgrading L<Test::Builder> to use L<Test2>.

=head1 FUNCTIONS

These can be imported, or called as methods on the class.

=over 4

=item %mod_ver = upgrade_suggested()

=item %mod_ver = Test2::API::Breakage->upgrade_suggested()

This returns key/value pairs. The key is the module name, the value is the
version number. If the installed version of the module is at or below the
specified one then an upgrade would be a good idea, but not strictly necessary.

=item %mod_ver = upgrade_required()

=item %mod_ver = Test2::API::Breakage->upgrade_required()

This returns key/value pairs. The key is the module name, the value is the
version number. If the installed version of the module is at or below the
specified one then an upgrade is required for the module to work properly.

=item %mod_ver = known_broken()

=item %mod_ver = Test2::API::Breakage->known_broken()

This returns key/value pairs. The key is the module name, the value is the
version number. If the installed version of the module is at or below the
specified one then the module will not work. A newer version may work, but is
not tested or verified.
