Upgrading to Prisma 4

In case you missed it, we held a livestream last week and walked through issues you may run into while upgrading to Prisma 4 and how to fix them!

Major improvements

Ordering by nulls first and last support (Preview)

In this release, we're adding support for choosing how to sort null values in a query.

To get started, enable the orderByNulls Preview feature flag in your Prisma schema:

 generator client {
   provider        = "prisma-client-js"
   previewFeatures = ["orderByNulls"]
 }

Next, run prisma generate to re-generate Prisma Client. You will now have new fields you can now use to order null values:

await prisma.post.findMany({
  orderBy: {
    updatedAt: { 
      sort: 'asc',
      nulls: 'last'
    },
  },
})

Learn more in our documentation and don't hesitate to share your feedback in this issue.

Fixed memory leaks and CPU usage in Prisma Client

In this release, we've fixed the following issues experienced when setting up and tearing down Prisma Client while running tests:

1. Prisma Client now correctly releases memory on Prisma Client instances that are no longer being used. Learn more in this GitHub issue
2. Reduced CPU usage spikes when disconnecting Prisma Client instances while using Prisma Client. You can learn more in this GitHub issue

These fixes will allow you to run your tests a little faster!

Prisma Studio improvements

We're refining the experience when working with Prisma studio with the following changes: 1. An always visible filter panel and functionality to clear all filters at once

1. Improved relationship model view with more visible buttons

Let us know what you think, and in the event, you run into any issues, please create a GitHub issue
