# Release Management
## Package management
LibreELEC is made up of over 800 packages which are in themselves developed by many other teams and groups across the Internet. These packages are maintained in the `packages` directory. An example of a package is **Linux** which has its main **LibreELEC** `makefile` as `packages/linux/package.mk`, or **Kodi** `packages/mediacenter/kodi/package.mk`.
The project team and Contributors prepare and regularly update the code that makes up the LibreELEC distribution. This is done by "bumping" the `PKG_VERSION` in the `package.mk` file and updating the other variables, code, patches and dependencies that make up the distribution. These are then rolled up into a [https://github.com/LibreELEC/documentation/blob/master/development-1/git-tutorial.md#pullrequests](https://github.com/LibreELEC/documentation/blob/master/development-1/git-tutorial.md#pullrequests "mention")and submitted as a change.
### Release Monitoring
The `update-scan` tool has been developed to check `PKG_VERSION` of packages against release monitoring sites. This tool currently uses **Anitya** from [https://release-monitoring.org/](https://release-monitoring.org) with the following distribution
An example of the output from `update-scan` is below:
```
$ tools/update-scan
Github api usage activated
Updates found:
Package | LE git master | upstream location
--------------------------------------------------------------
Pillow | 8.4.0 | 9.0.1
Python3 | 3.8.12 | 3.11.0a5
RPi.GPIO | 0.7.1a4 | 0.7.0
.
.
.
```
The tool provides a report at the end of the currency of the packages in the current checked out **LibreELEC** code.

Packages are ignored if either the `PKG_VERSION` *or* `PKG_URL` \_\_ are empty or hosted by **LibreELEC**.
For packages not known at the tracker - this means that the package is either not release monitored or not configured for release monitoring at .
The following image shows the **Projects of LibreELEC** monitored by **release-monitoring**.
Adding a project to the distro can be made by logging in using your **Fedora** ID.
Search for the project that you have developed the package.mk for and you want release-monitoring to monitor. In the example - we have added the distro **LibreELEC** to `aixlog`.
Click the `Add new distribution mapping` button within the Project (**aixlog** example.)
You need to choose **LibreELEC** from the **Distribution** drop down. Then click `+ Add mapping to project`.
{% hint style="info" %}
The Package Name must match the `PKG_NAME` variable from the **LibreELEC** `package.mk` file. The `Project name` from the Project in release-monitoring.org does not have to match the **LibreELEC** `PKG_NAME`.
