Not sure if these are updated in the version that just came out, but a few updates for those of you with the previous version of the guidebook:
At Solheimajokull and Reynesfjara (the black sand beach) parking was no longer free. Paid parking was required through the Parka app. There was no wifi and no other payment options listed, so not sure what to do if you are planning on travelling without cellular data.
At Gulfoss, as of 4/18 the lower parking lots and all the lower trails were still closed for the winter.
At Dyrholaey, the upper road to the lighthouse is now paved and easy to drive up.
