Thanks for the update…!

Hi,
Seems fixlet is not updated properly.

Relevance 9: Still have old sha value in fixlet.
And in Action script: Action required restart is still have old sha value

Please refer the below snip:

@amikush although the value in the pending restart and action requires restart statement does not equal the binaries SHA1, it will continue to work. But we’ll get this item corrected in a subsequent publish for consistency purposes. Please try again to patch and you’ll see that it works. Apologies for the inconvenience here. -Gus
