prisma/prisma 2.0.0-preview-6

on GitHub

Today, we are issuing the sixth Preview release: 2.0.0-preview-6 (short: preview-6).

Major changes

Next to a lot of bug fixes, this release ships with a completely overhauled core of the Prisma query engine which makes the resolution of Photon queries a lot more stable.

Unfortunately, due to the overhaul there is one known regression to be aware of: Required relations are not enforced as NOT NULL on the database level. They are enforced by the query engine though. This is intermediate until we have fixed a limitation in the query engine. You can track the progress of this issue here.
