 Sven, thanks for the reply. Your suggestions do not work - I still 
 get the March 2016 files. 
Ah, I think I know what may be happening here. Have you at some 
point selected A4-format documentation? (Under 
/Tools/Preferences/General there's an item "PDF manual preference" 
where you can select US letter paper or A4 paper.)
Here's the thing: each release package includes current versions of 
the Gretl User's Guide and the Gretl Command Reference (PDF files) 
in US letter format. But if you want the A4 versions they are 
downloaded on demand. And in this respect there's a gap in our 
updating logic: if you have once downloaded (for example) the A4 
User's Guide, then it will be found on your system thereafter and 
will not be downloaded again, even if it goes out of date. 
Uninstalling gretl won't help: the old A4 PDF files will not get 
deleted since they were not part of the initial gretl installation.
We need to figure out a proper fix for this, but in the meantime 
here are two possible work-arounds:
1. Select US letter format under Preferences, and you'll see the new 
PDF files that were installed with gretl 2016c.
2. Manually delete the old PDF files under the "doc" folder in your 
gretl installation. Then when you go to consult them the new 
versions will get downloaded from sourceforge.
On the other hand, if the Preferences/General dialog is NOT showing 
A4 as your preferred PDF format, then I don't know what's happening. 
I have verified that the 2016c release files on sourceforge contain 
the Guide and Reference as of July 6, 2016.
