These images are grayscale (only one value per pixel, not the three usual R/G/B) and lack an alpha channel.

The first thing you need is to add the missing alpha channel: Layer>Transparency>Add alpha channel

Then three ways:

#1: Given than the images are strictly black and white (no gray pixels), you can just use the "By Color Selector", click on an either black or white pixels to select that color, and hit [delete].

#2: Set the bucket-fill tool to Color erase mode, and bucket-fill with the color you want to make transparent

#3: Convert the image to RGB (Image>Mode>RGB) and then use the Color>Color to Alpha  (which is likely what you were used to do).

Converting the image to RGB is also an option before/after the first two methods, to export to the more common PNG variant.
