You can now download Cryptomator 1.5.0-alpha1 from our GitHub page.
This is not yet feature-complete and even misses a few things from earlier versions, since we decided to do a complete rewrite of the UI code.
This pre-release version does not yet support opening your existing vaults, because we want to broadly test the new vault format first. For production use please stick with 1.4.x for now.
Feel free to post any feedback below this post or on GitHub. Please refrain from opening new topics if you encounter any issues, so we can find all feedback in one place.
