 If you later switch away from Accelerate to direct TCP, provide the direct URL to the appropriate driver adapter (for example `PrismaPg`) instead of `accelerateUrl`.
 
+### SSL certificate validation changes
+
+Since Prisma ORM v7 uses `node-pg` instead of the Rust-based query engine, SSL certificate defaults have changed. Previously, invalid SSL certificates were ignored. In v7, you may encounter the following error:
+
+```bash
+Error: P1010: User was denied access on the database <database>
+```
+
+To fix this, either keep the previous behavior:
+
+```ts
+const adapter = new PrismaPg({
+  connectionString: process.env.DATABASE_URL,
+  ssl: { rejectUnauthorized: false },
+});
+```
+
+Or properly configure your database certificates using `node --use-openssl-ca` or by setting the `NODE_EXTRA_CA_CERTS` environment variable.

 ### Explicit loading of environment variables
 In Prisma ORM 7.0.0, environment variables are not loaded by default. Instead developers need to
 explicitly load the variables when calling the `prisma` CLI. Libraries like [`dotenv`](https://github.com/motdotla/dotenv) can be used to manage loading environment variables by reading the appropriate `.env` file.
