# Bytebase 3.20.1 - Jul 16, 2026

> Improvements and Bug Fixes

## 🎄 Enhancements

* **Plan deployment** — Enhance the deploy section to show task execution details inline, without opening a separate detail panel.

* Faster approval checks for multiple database changes, improved access-grants filtering, and `LIMIT`-aware row estimation.

* **Maximum role expiration** — Restore the workspace setting that was renamed to **Maximum request expiration** in 3.20.0. The two are now separate settings: **Maximum role expiration** caps how long a requested role can last, while **Maximum request expiration** caps just-in-time access requests. For Terraform configuration and migration, see the [Migration Guide](https://github.com/bytebase/terraform-provider-bytebase/blob/main/migration/3.20.3.md).

## 🐞 Bug Fixes

* Improve SQL Editor autocompletion and fix the high CPU usage it caused when entering or editing large multi-statement sheets.

* Fix stale syntax-error markers lingering in the SQL Editor after a statement became valid.

* Fix approval flow rule validation.

* Show the actor on bypass-and-deploy activity entries instead of an anonymous entry.

* Fix assorted UI issues: SQL Editor URL redirects and query-result display, schema editor preview for new tables, custom branding not refreshing, overly long statements slowing the page, and the initial setup flow.

* **PostgreSQL** — Keep `public` in the session search path when a schema is selected in the SQL Editor, so extension functions installed in `public` resolve again.

* **Oracle** — Fix schema sync failing when a view definition contains invalid UTF-8.

* **MongoDB** — Render doubles in mongosh notation instead of scientific notation across query results, the detail panel, copied values, and exports.

## ⚙️ 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](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.*
