After the release of 1.7.0-alpha1 we have been working towards the 1.7.0 release as described in our community update. We feel that the 1.7.0 branch is feature complete and while we're developing tests to find and fix possible regressions and older bugs, no new features or major changes are expected to be implemented before 1.7.0.
This means that the current code base (modulo any and all regressions we can find and fix) will become 1.7.0 when it's ready. To help you find the bugs we need to fix before the release, we have published 1.7.0-beta1. It's available as a Docker image from Docker Hub under the tag "ledgersmb/ledgersmb:1.7.0-beta1". See https://hub.docker.com/r/ledgersmb/ledgersmb/builds/
Additionally, the release can be downloaded as a tarball from the download site:
Robust and Flexible. No vendor lock-in.
