I am using QGIS 3.6.2-Noosa. Last time I merged rasters (a couple of weeks ago) I had options on the Raster Menu that are mysteriously gone now (I would merge via Raster>Miscellaneous>Merge). Now when I click on the Raster menu I have only two options: Raster Calculator... and Align Rasters...

I am not aware of having updated QGIS and cannot find documentation of Merge on QGIS' website. Any idea what is going on?
