Major improvements & new features

Human-readable drift diagnostics for prisma migrate dev

Database schema drift occurs when your database schema is out of sync with your migration history, i.e. the database schema has drifted away from the source of truth.

With this release, we improve the way how the drift is printed to the console when detected in the prisma migrate dev command. While this is the only command that uses this notation in today's release, we plan to use it in other places where it would be useful for debugging in the future.

Here is an example of how the drift is presented with the new format:

[*] Changed the `Color` enum
  [+] Added variant `TRANSPARENT`
  [-] Removed variant `RED`

[*] Changed the `Cat` table
  [-] Removed column `color`
  [+] Added column `vaccinated`

[*] Changed the `Dog` table
  [-] Dropped the primary key on columns (id)
  [-] Removed column `name`
  [+] Added column `weight`
  [*] Altered column `isGoodDog` (arity changed from Nullable to Required, default changed from `None` to `Some(Value(Boolean(true)))`)
  [+] Added unique index on columns (weight)

Support for .env files in Prisma Client Go

You can now use a .env file with Prisma Client Go. This makes it easier to keep database credentials outside your Prisma schema and potentially work with multiple clients at the same time:

example/
├── .env
├── main.go
└── schema.prisma

Learn more about using the .env file in our documentation.

Breaking change

Dropping support for Node.js v10

Node.js v10 reached End of Life on April 30th 2021. Many of our dependencies have already dropped support for Node.js v10 so staying up-to-date requires us to drop Node.js v10, too.

We recommend upgrading to Node.js v14 or greater for long-term support. You can learn more about Node.js releases on this page.
