Changelog

Varnish Custom Statistics 6.2.2 (2022-06-09)

• Fix an issue that occurs when using -O option: On write failures, VCS would leak the old connection when reconnecting to the socket.

• Introduce per bucket histograms. https://docs.varnish-software.com/varnish-custom-statistics/use-cases/#generating-histograms
• Fix an issue in rpm pkgs where the service is disabled after upgrade (Note: service will still be disabled on this upgrade, since it is part of the old package uninstall policy).

Varnish Custom Statistics 6.1.0 (2020-11-16)
