Difference between SAS 9.4 M6 and M7

Hello all,

We are preparing an upgrade for our SAS 9.4 M4 (data management) environment. One of the questions we still need to be answer is which maintenance release we should install, M6 or M7. We are careful to be install the last version of maintenance release M7, because it's recently released (September). So, I want to know what are the difference is between these two versions. Is there an easy way to compare the difference between the maintenance releases?

Thanks in advance.

If you make use of hash objects, stay with M6. We discovered a bug when datasets are read into a hash with a WHERE= dataset option that leads to excessive memory consumption.

Hello @sergie89 , good question.

You can start by checking by yourself the Guide for Updates and the What's new section for the maintenances and per product.
