Patch History

From Dota Auto Chess Wiki
Jump to: navigation, search
The goal of this article is to slowly build up an easy to digest and detailed history of the changes to Dota 2 Auto Chess. If all you care about are the most recent changes or bug fixes, then you can go to the official workshop page where the creator posts the most recent change notes.

If there is enough interest in the game, and myself and/or others have the time or care to build up the systems then this page would server as an improved version of the workshop page. Listing changes here and integrating them would benefit the reader with keywords linked to other related resources, or the individual filtering of a single chess pieces history. Which could give greater context as to how something has changed over time.

Patches are updates to the map that have been made by the map creator. A patch could be as small as a single bug fix, or as large as a major balance rework. Most of the patch notes are succinct enough, but sometimes the translation from Chinese to English can be lost. The exact words should be placed as to not infer what a change could mean.
