- A patch can declare compatibility with specific packages and versions,
but patches can still be executed on any package or version.
It is recommended that compatibility is specified to present known compatible packages and versions.
- If `compatibleWith` is not used, the patch is treated as compatible with any package
- If `compatibleWith` is not used, the patch is treated as compatible with any package
- If a package is specified with no versions, the patch is compatible with any version of the package
- If an empty array of versions is specified, the patch is not compatible with any version of the package.
This is useful for declaring incompatibility with a specific package.
This is useful for declaring incompatibility with a specific package.
- A patch can raise a `PatchException` at any time of execution to indicate that the patch failed to execute.
