2018-11-12 - Varnish 6.0.2 released, official Long Term Support¶

We are happy to announce the release of Varnish Cache 6.0.2.

This release is recommended for everyone running 6.0, and it contains many bug fixes and some new features.

At the same time we bring you the news that that 6.0 will maintained much longer than other Varnish Cache Releases, and that new repositories, Varnish 6.0 LTS, are introduced.

If you are currently using official packages, you need to change to the new LTS repositories to get 6.0.2. Please follow the instructions on the release page to set up the new repository for your platform.

The packaging of this release differs slightly from previous Varnish versons. This is described in the upgrading notes 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.

At some point the previous LTS, Varnish 4.1, will reach its End of Life. It was first released in September 2015, and now is the time for users to start upgrading to Varnish 6.0 LTS.

If you are still using Varnish 4.1, you should be able to migrate to 6.0 without touching your VCL. In our experience so far, upgrading is very straightforward.
