# Deprecations and removals

This page contains information on the deprecation and removal of SonarQube Server features and API endpoints.

* Each deprecated feature or API endpoint will be removed in a future release. We recommend to start using its replacement (if any) as soon as possible.
* To check for breaking changes before you upgrade, read the [Release update notes](/sonarqube-server/2025.1/server-update-and-maintenance/release-notes-and-notices/release-upgrade-notes.md) for all the versions between your current version and the target version.
* Plugin API deprecations are announced in the [sonar-plugi-api GitHub repository](https://github.com/SonarSource/sonar-plugin-api/releases).

**Deprecation time frame**

A deprecated feature can be dropped in the year following the year it was deprecated, after the new LTA, with a minimum of 6 months after deprecation.

For example, a feature deprecated in the 2025.2 version is kept until the 2026.1 LTA (Long-term active) version and dropped in the 2026.2 version or later. See [Release cycle model](/sonarqube-server/2025.1/server-update-and-maintenance/update/release-cycle-model.md) for more details.

A backward-incompatible change or dropping of a public API endpoint, a workflow, or a feature is subject to the deprecation. Once deprecated, they will be removed in a future version.

**Deprecation of property encryption on the scanner side**

Property encryption on the scanner side is now deprecated.

**Removed sonar.password property**

The `sonar.password` scanner property that was deprecated in SonarQube Server 9.8 has now been removed.

**Removed password hash**

The BCrypt hash method used for passwords was deprecated in SonarQube Server 8.9. It has now been removed. As a result, the passwords of users who have not logged in since SonarQube 8.9 are deactivated and an admin must reset them if these users need to log in again

**Removed complexity metrics**

The following complexity metrics, which were deprecated in SonarQube Server 6.7, have now been removed:

* `file_complexity`
* `complexity_in_classes`
* `class_complexity`
* `complexity_in_functions`
* `function_complexity`
* `function_complexity_distribution`
* `file_complexity_distribution`
