# Bytebase 3.8.1 - Jul 17, 2025

> New Database CI/CD Experience Preview

## 🔔 Notable Changes

* **New database CI/CD experience** is available in preview. Enable it from the profile dropdown.
* `default_expression`, `default_string`, and `default_null` fields in `ColumnMetadata` are removed from the API. Use the unified `default` field instead. This affects APIs such as `GetDatabaseMetadata` and `GetChangelog`.

## 🚀 New Features

* In **SQL Editor** and **audit log**, show masking reason for sensitive data.

## 🎄 Enhancements

* Data export files are available for 24 hours with unlimited downloads.
* **SQL Server** -  Support Spatial Index in schema rollback and synchronization.
* **Redshift** - Support turning off transaction wrapping using the `-- txn-mode=off` directive before the SQL statement.
* **Terraform** - Support more policies:
  * rollout policy (for environments)
  * copy data policy (for environments and projects)
  * data source query policy (for environments and projects)
  * See [example configurations](https://github.com/bytebase/terraform-provider-bytebase/blob/main/examples/setup/environment.tf#L41).
* Introduce a new 8-part series of [Terraform Provider Tutorials](/integrations/terraform/overview#tutorials).

## ⚙️ Install and Upgrade

* [Fresh install](/get-started/self-host/deploy-with-docker)

*Before upgrading: 1) Back up the [metadata](https://www.bytebase.com/docs/administration/back-up-restore-metadata/) — in-place downgrade is not supported. 2) Do not run multiple containers on the same data directory. 3) Terraform users: upgrade Bytebase server first, then apply the new Terraform config.*
