* The packaging of this release differs slightly from previous Varnish versons. This is described in the `upgrading notes <docs/6.0/whats-new/upgrading-6.0.html#packaging-changes>`_ for 6.0. These changes were originally intended for the initial 6.0 release, but unfortunately they did not make it into the 6.0.0 or 6.0.1 packages.
Varnish Cache 6.1 is a continuation of the development of Varnish Cache 6, and it brings new features and greater stability without any major breaking changes to most users' setups.
If upgrading from 6.0, you should not expect to encounter any problems. However, VMODs and and VUT programs have to be recompiled.
