I'm writing on behalf of the WMF Web team that's developing the Desktop Improvements. Your wiki is among early adopting projects. This means your community and readers are able to see the changes first.
The upcoming week (21-24 September) we will move the search widget to the header (by the logo). The widget will be in a more prominent location, more easy to find, and more difficult to forget where it is. Later, we will run tests where only a half of tested users will see the widget in the new location. Hopefully, these users will search more often, and the widget will stay in the header. You can learn more on a page dedicated for the search widget improvements.
If your community uses non-wiki channels of communication widely, please let me know so I could post this information there, or just feel free to share the news by yourself.
To see our plans for more changes, see a list of features to be improved.
