Document Engine 1.2 introduces some potentially breaking changes. To determine if you need to take action, check your implementation and refer to the information below.

## PostgreSQL database TLS certificate verification

This release introduces new [options](https://www.nutrient.io/guides/document-engine/configuration/options.md) to control PostgreSQL connection encryption (in case `PGSSL` is set to `"true"`). By default, the certificates installed in the container are used to verify the server certificate. If you need to use a custom CA certificate, you can provide the path to the CA certificate file using the `PGSSL_CA_CERT_PATH` or `PGSSL_CA_CERTS` options.

All new options:

- `PGSSL_CA_CERT_PATH` — Optional path to the CA certificate file used to verify the server certificate. Mutually exclusive with `PGSSL_CA_CERTS`.

- `PGSSL_CA_CERTS` — Optional CA certificate used to verify the server certificate. Mutually exclusive with `PGSSL_CA_CERT_PATH`.

- `PGSSL_CERT_COMMON_NAME` — Common name of the server certificate. Defaults to the value of `PGHOST`.

- `PGSSL_DISABLE_HOSTNAME_VERIFY` — A Boolean string that can be used to disable verification of the server certificate’s hostname. Defaults to `"false"`.

- `PGSSL_DISABLE_VERIFY` — A Boolean string that can be used to disable verification of the server certificate. Defaults to `"false"`.

## Database migrations

This release includes one database migration:

- `add_backend_info_to_pdfs_and_attachments` — Adds `backend_info` columns to the PDFs and attachments tables to support multiple S3 bucket configurations. The migration runs automatically during upgrade.
