Collector 3.0.0

We are pleased to announce the release of Snowplow Collector 3.0.0!

The main change compared to the previous version (2.10) is that we moved from Akka HTTP to http4s as our HTTP framework.

The version of Akka we were using no longer receives security patches; subsequent versions of Akka are only available under a commercial license from Lightbend. http4s has no such limitations, as it’s released under the Apache 2.0 license. Moreover, we have been using http4 in all other http-enabled services (e.g. Enrich). Having the same framework across our codebase helps us share code between applications and develop faster.

We’ve strived to maintain full compatibility between 2.x and 3.x versions of the Collector, but there are still a few adjustments you will need to make to your configuration. See the upgrade guide for more details.

Note that per our recent licensing announcement, Snowplow Collector 3.0.0 is released under the Snowplow Limited Use License Agreement.
