# Bytebase 3.9.2 - Aug 28, 2025

> Support hard-delete for projects and instances

## 🚀 New Features

* Add support for hard-delete of projects and instances (resources must be archived first).
* Add support for adding/removing changes in draft plans.

## 🔔 Notable Changes

* Streamline approval by enabling one-click ready for review.
* Update `UpdateMask` values in `UpdatePolicy` to observe AIP. Use field names only; oneof type names are omitted. ([PR #17240](https://github.com/bytebase/bytebase/pull/17240))
* **Terraform** - Deprecate `column`, `member` and `action` field in the `masking_exception_policy`, use `columns`, `members` and `actions` instead. Example: [data\_masking.tf](https://github.com/bytebase/terraform-provider-bytebase/blob/main/examples/setup/data_masking.tf#L113)

## 🎄 Enhancements

* Add support for empty environments in instance and database resources.
* Enhance SQL Editor performance.
* **Entra ID** - Normalize SCIM user emails to lowercase for authentication.
* **PostgreSQL** - Add support for `CREATE RULE`.
* **API** - Add support for pagination and filtering for group API.
* **Terraform** - Add support for `raw_expression` in the `masking_exception_policy`. Once provided, it is used as the CEL expression, and all other ( `database`, `schema`, `table`, `columns`, `expire_timestamp`) fields are ignored.
* **Terraform** - Add support for empty environments in instance and database resources.
* **Terraform** - Add support for filters in group list data sources.
