What is Wog?

A friend told me about some "Heroes 3.75" and even promised to bring them... I haven't seen him for about three days, but he was very confident about it. And what's the difference between 3.58 and 3.5?

And also: when will 3.59 be released?

Most likely, your friend mistook one of the many fakes for WOG. It is recommended to download the real WOG only from the official project website.
Also, be wary of scammers who will try to sell you the "latest version," "amazing sequel to WOG," etc. WOG has always been and remains a free project, so any attempts to profit from the selfless work of more than 60 fans of the game, we hope, will be met with appropriate skepticism.

The difference between 3.51 and 3.58 is roughly the same as between a Zaporozhets and a Mercedes. I recommend that you install only version 3.58f, as this is the most stable and playable version at the moment.
