# Bytebase 3.10.1 - Sep 25, 2025

> Support key–value project labels

### 🚀 New Features

* Add project labels, up to 64 key–value pairs.

### 🔔 Notable Changes

* Environment Rollout Policy:
  * The **Issue Creator** and **Last Issue Approver** roles are being sunset. They no longer appear in new environments, while existing environments remain unaffected. Full removal is scheduled for the *next release.*
  * The **force rollout** mechanism will be replaced by configurable rollout conditions in the *next release*, providing more flexibility and stronger security.
* Restrict **Disallow issue creation for SQL review with errors** option to project level only (was applied to both project and workspace).
* Remove settings pages in **Editor mode**.
* **API** - Change database label filter syntax to `labels.region == "asia"` (was `label == "region:asia"`).
* **API** - Deprecate the standalone `DisableCopyDataPolicy` and migrates its functionality to `QueryDataPolicy`.

### 🎄 Enhancements

* Improve Data Export issue page:
  * Support updating targets before issue creation.
  * Display tasks in a flat list instead of grouping by stages.
* Add option to switch [transaction mode](/change-database/transaction-mode) in Plan.
* **MySQL** - Add isolation level selection when transaction mode is on.
* **Postgres** - Add role selection for executing SQL in Plan.
* Support `instance_id` in risk condition.
* Optimize advanced search with cached filters.
