Cardano(ADA) just released its 1.5 update. This is an important update as it moves from the old blockchain into a transitional blockchain that will facilitate the Shelley transfer. There will be a hard fork, then Shelley will begin releasing and then afterwards, there will be a hard fork onto the Shelley release and Byron will be retired. There are going to be some big announcements at the Conference from April 14th-24th and hopefully the Shelley releases will start by then.
