+## 3.5.8
+At request for Felipe Nevinski, I am having the ultra orbit option in nmea2snr check for three different files.
+I am skeptical ... but I could be wrong.
+
 ## 3.5.7
 
 small issue with bkg high rate downloads. now fixed.

     Note from KL: I believe lowercase is also allowed (and preferred), but the A at the end is still set to be upper case
     (I believe) The SNR files are stored with upper case if given upper case, lower case if given lower case.
 
+    At request of Felipe Nievinski, the ultra option (which points to GFZ ultrarapid orbits) will
+    first look for the orbit on (requested doy, hour 0), then (doy-1, hour 0), and then (doy-1, hour 12).
+    I do not think this first search is correct - but I don't think it makes the code crash so I will
+    keep it there for now.
