-decision that can be verified by checking the warrant canary document in April, +

-2. In the previously mentioned document designed by wneriez in April 2020, +
-the date in its statements was mistakenly written as "April 15th, 2019", +
-which was a typo, but cannot be changed due to the nature of digital signature. +
-We declare that it's hereby corrected to "April 15th, 2020". +

-3. A new member, vimacs (0xEA2DB82FE04A9403) has became a new signer since this +
