 # EESSI Versions
 
-EESSI is organized in different dated versions. Each EESSI version contains a version of the [compatibility layer](../compatibility_layer.md) and its' own set of software applications. In addition, a particular EESSI version will target a different set of [common toolchains](https://docs.easybuild.io/common-toolchains/) to build software with. As an example, the first  EESSI version was released in June 2023 and is named `2023.06`. This version's compatibility layer is based on a particular "version*" of [Gentoo Prefix](https://wiki.gentoo.org/wiki/Project:Prefix) and the software layer contains software built using the `foss/2022b`, `foss/2023a`, and `foss/2023b` [software toolchains](https://docs.easybuild.io/common-toolchains/#common_toolchains_overview) as defined in EasyBuild.

 The vast majority of changes are fully transparent to users. Apart from selecting a newer version when starting up EESSI, and accessing an update collection of software, the functionality remains the same, with little to no extra effort needed to use a new version compared to and older one.
