It's possible to load a whole slew of features in one go, using
a I<feature bundle>. The name of a feature bundle is prefixed with
a colon, to distinguish it from an actual feature. At present, the
-only feature bundles are C<use feature ":5.10"> and C<use feature ":5.10.0">,
-which both are equivalent to C<use feature qw(switch say state)>.
+only feature bundle is C<use feature ":5.10"> which is equivalent
+to C<use feature qw(switch say state)>.
-In the forthcoming 5.10.X perl releases, C<use feature ":5.10"> will be
-equivalent to the latest C<use feature ":5.10.X">.
+Specifying sub-versions such as the C<0> in C<5.10.0> in feature bundles has
+no effect: feature bundles are guaranteed to be the same for all sub-versions.
