# 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`

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.sonarsource.com/sonarqube-server/2025.1/server-update-and-maintenance/release-notes-and-notices/deprecations-and-removals.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
