Define "earlier" ? The permissions handling has been extensively rewritten
since 1.7.34.
Probably from a few months ago, but I can't confirm. I've been trying to
figure out how to revert back to an earlier version to verify this. Where
can I find archived versions of Cygwin?

Which will then prevent opening it from Explorer by file association.
Not really... In the above example if I 'chmod 644 newfile.txt' in Cygwin,
Windows can still open up the file in notepad by just double-clicking on the
file. Checking the file permission under Windows shows "Special permissions"
checked. It also works even if I remove the ACL bit shown below:
[user@hostname ~]$ chmod 644 newfile.txt
[user@hostname ~]$ ls -l newfile.txt
-rw-r--r--+ 1 user Domain Users 0 Sep 23 10:30 newfile.txt
[user@hostname ~]$ setfacl -b newfile.txt
[user@hostname ~]$ ls -l newfile.txt
-rw-r--r-- 1 user Domain Users 0 Sep 23 10:30 newfile.txt
At this point I double-clicked on the file in Explorer and it opened in
Notepad, which I then added a line of text and saved it.
[user@hostname ~]$ ls -l newfile.txt
-rw-r--r-- 1 user Domain Users 18 Sep 23 10:32 newfile.txt
[user@hostname ~]$ cat newfile.txt
this is a new file
[user@hostname ~]$

Likely it is caused by the change in Cygwin permissions handling.
It now correctly inherit permissions in most cases.
