 Much quality. Many standards. The **Macro Core** library exists to save time and development effort! Herein ye shall find a veritable host of MIT-licenced, production quality SAS macros. These are a mix of tools, utilities, functions and code generators that are useful in the context of [Application Development](https://sasapps.io) on the SAS platform (eg https://datacontroller.io). [Contributions](https://github.com/sasjs/core/blob/main/.github/CONTRIBUTING.md) are welcome.

 We are currently on major release v4.  Breaking changes should be marked with the [deprecated](https://www.doxygen.nl/manual/commands.html#cmddeprecated) doxygen tag.  The following changes are planned when the next major/breaking release (v5) becomes necessary:
 
-* mf_getuniquelibref.sas to have the deprecated maxtried parameter removed (no longer needed)
-* mp_testservice.sas to be renamed as mp_execute.sas (as it doesn't actually test anything)
