v0.2.0

There are not BC breaks coming from the underline components. If you have a running sandbox and you want to update it with this version you just have to checkout v0.2.0 and a docker-compose stop, docker-compose rm, docker-compose up -d is enough.

A few things to know:

1. We store a cached version of Osie in ./state/webdir/misc. If you do not remove that the new one won't be installed.
2. tink-server uses migration now. In this way, we can automatically update the database schema if needed. Migration runs as part of docker-compose. So you should see a new container called tink-server-migrations in status Exit, which means that migrations ran on your system.
3. If you are running sandbox in your own way, just a tip. generate-envrc.sh uses a new file called ./current_versions.sh. It exports a couple of variables that we use to generate our new shiny binaries as well.
