# Roadmap

** English (en)** |

**Русский (ru)**| Edit

This document gives an idea of the current status of the various parts of Lazarus and also helps new contributors to find a suitable place where they can help. It also shows the people implementing the various parts and the targets.

**Legend:**

Working - Stable, most or all parts implemented.

Partially Implemented - Works, but has some features missing

In progress - Someone is working on this

Not Implemented - Nothing done, needs your help

Deprecated - Outdated, obsolete, usage not recommended for new projects

Unknown - Please review whether this component is working, and set its status here
