# Bytebase 3.21.1 - Aug 13, 2026

> DynamoDB Cross-Account AWS Credentials

## 🎄 Enhancements

* **DynamoDB** — Configure per-instance AWS credentials, including a cross-account role ARN and external ID. A stored role ARN is now enforced when connecting — verify yours with Test Connection after upgrading.

## 🐞 Bug Fixes

* **SQL Editor** — Fix workspaces configured to land on the SQL Editor redirecting to the default landing page instead, after signing back in.

* **Schema Sync** — Fix the target database search returning cut-off results.

* **LDAP** — Fix multiple Test Connection issues: it no longer reports a false error for correctly configured providers, now runs a real sign-in test showing the mapped fields and directory attributes, and the Phone field mapping now takes effect.

* **CosmosDB** — Fix query results not showing the executed statement, and exports omitting the target container.

* **Oracle** — Restore support for connections to Oracle 11g.

## ⚙️ Install and Upgrade

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

* [Upgrade](/get-started/self-host/upgrade)

*Before upgrading: 1) Back up the [metadata](/get-started/self-host/upgrade#back-up-and-restore) — 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.*
