 * Fixed issue with module name checking which caused modules to fail to build on certain linux distributions
 * Exact module version is fetched correctly at build-time to ensure that new releases do not affect upstream dependencies
 * Issue involving priority between some test versions fixed
+* `make patch` when there are no patch files will no longer return an error code.
 
 ## Other changes
 * Removed `require` as a submodule and merged it into `e3-require`.
