This is a patch release that optimizes statistics inserts into the database, lowering CPU usage of Brainz.
It also normalizes dynamic backends statistic counters for the
vmod-goto. Meaning that stored statistic counters
vmod-goto in Varnish Controller will have the ID from the counter name removed.
Upgrading from 2.0.4 does not require any configuration changes to any of the components.
See Varnish Controller Changelog.
This update is recommended for all users.
