Because 11.49.6030 was implemented before the most recent major update, i.e last Winter Update. Usually, the (most recent) is removed from all versions when a major update is released.
I thought our de facto standard was to only refer to major (spring, summer, autumn, winter) updates as "most recent" and not other smaller patches. Often because only the major version introduce (a significant amount of) new content, which would even use the implemented parameters. Another convenience is the frequency of updating this template is strongly reduced if only needed for large updates. -- Bennie (talk ~ fellows) 11:26, April 15, 2018 (UTC)
