2018-06-08 - Publically available packages from UPLEX

The varnish-cache contributors from UPLEX are happy to announce an alternative source for varnish binary packages for Debian, Ubuntu and RHEL/CentOS (work in progress).

Debian/Ubuntu packages are based on fairly recent varnish-cache master snapshots and are expected to be updated on a bi-weekly basis, synchronized with the official varnish-cache weekly builds.

The main purpose of the UPLEX Packages is to provide simple and efficient access to up-to-date varnish builds and a matching range of additional vmods which are not commonly found in package repositories like blobdigest, re, re2, geoip2 and dcs in addition to the varnish-modules vmod bundle. Other will be added over time.

This packaging effort is still in its early stages and will grow over time.
