Map Versions List

This list is a rough list of every date of every map file that came out of Valve from 1998 to 2017.

How It Works:

The Hammer used today in every branch of Source was first compiled on October 24th, 1996. In every subsequent compile of the source code, this snippet will check how many days it has been since that date (Build 0). The version number will correspond to the number of days it has been since Build 0. During the development of all Half-Life and Source engine games, Hammer's source code was compiled many times a week, if not many times a day. VMF files save the Hammer version number that the map was first saved with as editorversion in plain text.

This version number can be added to October 24th, 1996 and it can be found out when the version of Hammer used to create that map was compiled. This is the NET (no earlier than) date. This means that the VMF cannot have been last modified before the date specified. This is vital in figuring out the dates of maps in the WC Mappack and Episodic Mappackleaks that have incorrect "Last Modified" dates. It can be an interesting insight into the development of these games.

The entries are sorted by folder alphabetically, and the VMFs are sorted by earliest date.
