Hi,
currently we work hard to add new features and to improve some parts for release version 6.0. The feature list for version 6.0 is growing and we use the current flow to add more features and to improve more parts of the application. As soon as we have a stable release tag we will publish the new version.
We would also like to make you aware of bringing in your ideas and desired feature so that we can decide what we can do or add to the next version. A lot of features are user driven. Send us your wishes and we will schedule them for the next releases.
