@subsubsection{Version Exceptions}
To make supporting multiple versions of Racket easier, the @tech{package
catalog} software supports @deftech{version exception}s. Version exceptions
allow package authors to specify alternative @tech{package source}s to be used
when installing a given package using a specific version of Racket.
For example, a package that uses on Racket 6.0-specific features could provide
a @tech{version exception} for Racket 5.3.6 using a different branch in the
package's Github repository, or a different zip archive, as package source.
Users installing the package from Racket 6.0 will use the default source for
the package, while those using Racket 5.3.5 will use the alternative branch /
archive.
For more details, see @secref{catalog-protocol}.
