# Bytebase 3.22.1 - Sep 10, 2026

> GPT-5 Support for AI Features

## 🎄 Enhancements

* The Grant Access account picker can now search for existing service accounts by name or email, instead of requiring their exact auto-generated email address.

* **AI Provider** — Support GPT-5 models for AI features, alongside existing GPT-4o support.

## 🐞 Bug Fixes

* Fix syncing many databases at once exhausting the metadata database's connection pool.

* Fix creating an access grant failing when its SQL statement is very long; show a clear size-limit error instead.

* Hide the unassign action for databases on a project-scoped instance — moving them to another project was never supported.

* **PostgreSQL** — Fix the "Require primary key" SQL review rule flagging unrelated `ALTER TABLE` statements on a table that already had no primary key.

## ⚙️ 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.*
