#Amethyst v0.87.0: Data Vending Machines (DVMs) and Gossip Model

This version adds support for Data Vending Machines for content discovery. You can request a job by simply navigating to the 4th tab and choosing one of the DVMs. It also starts our support for the Inbox/Gossip model. The relay setup screen has been rewritten to support the many types of relays Amethyst will start to use. Please add your relays as you see fit.

Our video caching system has been improved. Most of the high-bandwidth use of the app in the last month has been due to a faulty caching system for some video types. The app was just downloading them at every playback. In a similar way, the caching system for encrypted events has been massively improved. The app should feel visibly lighter at this point.

If you generated your keys from NIP-06 seed words you can now type them on the login screen to start the app. We are not generating seeds yet, but this will be available in the upcoming versions.

We are also moving to deprecate and remove most of the NIP-04 usage in the app. In the future, users won't be able to send new NIP-04 DMs but the history of past DMs will be available for as long as we can support it.
