# 技术栈

The following describes the tech stack for Chamilo 2.0. All versions stated here are likely to change as new versions of Chamilo are released. Version numbers use [Composer's versions notation](https://getcomposer.org/doc/articles/versions.md) which set rules to allow for some flexibility around versions.

Including hierarchical dependencies, Chamilo uses several hundred Free Software libraries. This list only includes the ones we use the most and that will likely affect the work of a Chamilo developer every week or so. We are greatful to all other Free Software developers out there making ou work easier, more maintainable and more secure.
