A long-awaited feature in the ZPE was the request for an updater built-in to the interpreter and parser. So now with ZPE 1.6.8.1 you can, although a minor update, it is actually a big update for it.
This is a long awaited feature and it's very easy to do. ZPE 1.6.8.1 is now also available to download from my website as of today. To run the update, simply type:
zpe --update
By reference-style variables have yet to be fully implemented and are partially implemented in ZPE 1.6.8.x. They've been disabled within the release versions.
With 2019 just around the corner, ZPE 1.7.0 is also just about ready to be started and readied for release. ZPE 1.7.0 is bringing some performance improvements and one or two new syntax features that aim to make ZPE even better. ZPE 1.7.0 will also bring an automatic updater, expanding on what ZPE 1.6.8.1 brought. Unfortunately, ZPE 1.6.9 which I had hoped to bring out before the end of the year, has been scraped due to the lack of time.
