Patches are distinct from Hotfixes in that they require extended downtime to implement and contain more and larger changes. Hotifixes contain minor changes and bug fixes, and occur much more frequently, they also do not update the game's version.
The current version of WAR (related to the most recent patch) can be found on HammerWiki's main page.
Please note that as the original release of WAR counted as version 1.0.0, subsequent patches increment this number by 0.0.1 for smaller updates or 0.1 for larger ones.
