Prisma 1.2.0 (2018-02-13)

CLI

Added cascading deletes https://github.com/graphcool/prisma/pull/1825. Check the documentation to see how it works!
Fixed AND and OR filters for deleteMany and updateMany https://github.com/graphcool/prisma/pull/1879
The nested update and upsert mutations are now available when only one type in the relation has a relation field https://github.com/graphcool/prisma/pull/1878
Improved upsert mutations https://github.com/graphcool/prisma/pull/1878
Added a deploy error if the old @defaultValue(value: "") syntax is used in Prisma instead of the new @default(value: "") https://github.com/graphcool/prisma/pull/1871
Updating an optional value to null is now always possible https://github.com/graphcool/prisma/pull/1864
Thanks to @seanchambo for fixing a bug where upsert would sometimes fail due to wrong argument order https://github.com/graphcool/prisma/pull/1822
