@tyler-lutz There's no description in the PR or the commit and github doesn't provide any diff at the file execution flag level.

What did you do to set these as executable? Was it just a chmod +x or did you use git update-index?

[tyler-lutz]

I just used chmod +x

@AristurtleDev you can see in the files changed section the mode modification:

644 -> 755 means he added executable bit for each category to the file, each one of those numbers represents a category (owner, group, others), and each number uses 3 bits for read(1 << 2), write(1 << 1) and execute(1 << 0).
