Not 100% sure how to answer this question. As written (which may be related to a language issue) the answer is yes because issues that are identified are corrected. As perhaps understood to be meant, I have been able to successfully use EP4 as provided from GitHub on ZC 1.5.6c. Currently, one of the added features is not 100% complete.

The new feature of using the extension of _en or similar to denote a specific language works for the full import; however, does not for one or two of the other imports.

Note, that this new feature has been incorporated to allow continued use of the import file(s) as they were (a language dependent field ending with the language_id associated with how that database is setup) but it also offers some override type features where if both the language_code (e.g. en, de) and language_id were used then one overrides the other.

Further note, that although I chose to be somewhat forceful in discussion with a recent user at the cost of being seen as a jerk, the information obtained led to a solution that resolved the issues that otherwise were going to be ignored.

As far as the software with Zen Cart 1.5.6c there is nothing done to that version of software affecting this, the issues if any are or expected to be related to php versions.
