The Core Components are designed to be flexible and compatible with all supported AEM versions. Because of this a release of the components can contain multiple versions of the same component.
The following tables illustrate the compatibility of the releases of the Core Components along with which component versions are contained in which releases.
The following table, the contents of which are available on GitHub with full release details, gives an overview of the releases of the Core Components and their compatibility with AEM releases and Java versions.

As with AEM, Adobe recommends that developers use the latest release and versions of the Core Components available that is compatible with the version of AEM that they are running in order to benefit from the most up-to-date fixes and features.

Core Components are distributed via GitHub. This allows Adobe to more quickly add functionality to the components and also allow for community input outside of the AEM release cycle.
The Core Components are made available with defined AEM versions with which they are compatible. This means that one AEM version may support multiple versions or releases of the Core Components. This gives more flexibility than the former Foundation Components, which were tied to a specific version of AEM.
The major iteration of the Core Components are the versions. Each component has a version. Versions are denoted with v appended with a nonzero, positive integer such as v1 and v2. Versions are incremented only for changes that are not backward-compatible, which is normally the case for the introduction of new features and functionality.
Developers and administrators can recognize versions of the core components by a number in their resource type paths, and in the fully qualified Java class names of their implementations. This version number represents a major version as defined by semantic versioning guidelines.
For more details about core component versions, see the developer documentation of the Core Components.
The core components are made available through releases and represent the actual published artifacts available on GitHub. Releases are denoted with a decimal number of the format X.Y.Z and collect all core components together as a deliverable package.
Releases can contain multiple versions of the same component.
The same version of a component can appear in multiple releases.
Core Components are an integral part of AEM and supported as is, under the same terms and conditions as if they were delivered as part of the Quickstart.
Like other product features, the general rule of end-of-life is:
This gives customers at least one release cycle to move to the new version of the component, before support ends.
The version of each component clearly states the AEM versions that it supports. When support ceases for a version of AEM, then so does the support of the Core Components for that version of AEM.
For details about the support of component customizations, see the Customizing Core Components page of the relevant Core Components Version.
Adobe’s development emphasis has shifted to the Core Components and new features will continue to be added.
Nearly all Foundation Components have been deprecated with AEM 6.5 and only major bug fixes will be considered for the Foundation Components going forward.
