I just created:

-rw-rw-r--. 1 gbc difx  54M Mar 26 10:54 DiFX-2.5.2.tgz
-rw-rw-r--. 1 gbc difx  54M Mar 26 10:54 DiFX-2.5.3.tgz
-rw-rw-r--. 1 gbc difx 105M Mar 26 10:54 DiFX-2.5.4.tgz
-rw-rw-r--. 1 gbc difx 105M Mar 26 10:55 DiFX-2.5.5.tgz
-rw-rw-r--. 1 gbc difx 106M Mar 26 10:54 DiFX-2.5.tgz
-rw-rw-r--. 1 gbc difx 120M Mar 26 10:55 DiFX-2.6.2.tgz
-rw-rw-r--. 1 gbc difx 123M Mar 26 10:55 DiFX-2.6.3.tgz
-rw-rw-r--. 1 gbc difx 120M Mar 26 10:55 DiFX-2.6.tgz
-rw-rw-r--. 1 gbc difx 102M Mar 26 10:55 DiFX-2.7.1.tgz
-rw-rw-r--. 1 gbc difx 103M Mar 26 10:55 DiFX-2.7.tgz
-rw-rw-r--. 1 gbc difx 124M Mar 26 10:56 DiFX-2.8.1.tgz
-rw-rw-r--. 1 gbc difx 124M Mar 26 10:55 DiFX-2.8.tgz

(I was wrong, I'd deleted some of the older or buggier releases.)  I can 
shove them into github or else some other place as directed...  This 
collection is 1.3 GB.
