-None.
+. Due to personal reasons, wnereiz (0xFDFF2E13AA25BE72) voluntarily decided
+to quit from the warrant canary team and he is no longer a signer of the
+warrant canary documents since April 15th, 2020. All statements from the
+warrant canary documents before this date are still valid. This is an official
+decision that can be verified by checking the warrant canary document in April,
+signed by wneriez.
+. 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".
+. A new member, vimacs (0xEA2DB82FE04A9403) has became a new signer since this
+month. You can validate the new keys by cross-checking the other two copies of
+this document, signed by biergaizi and persmule.
+. Due to the ongoing security issues of OpenPGP keyservers, it makes signature
+verification an issue and somewhat a challenge. For completeness, complete
+procedures for canary verification has been added.
+Canary Verification Procedures
+~~~~~~~~~~~~~~~~~~~~~~~~
+. To verify biergaizi's signature...
+    a. Obtain the public key from any traditional OpenPGP Keyserver, such as
+    https://keyserver.ubuntu.com, and import the public key. The fingerprint
+    is 0x255211B2395A5A3E0E48A0F1FAD3EB05E88E8D6D.
+    b. Use the latest GnuPG in any operating system.
+. To verify persmule's signature...
+    a. Unfortunately, it's not possible yet. Recent attacks on OpenPGP key-
+    servers have raised great security concerns within the community, as a
+    countermeasure, persmule's new public key has been published to the
+    https://keys.openpgp.org/ keyserver, but without a User-ID. Currently,
+    it's impossible to import a OpenPGP public key without User-ID for a
+rd-party to verify the canary document signed by persmule.
+    b. We are looking for a solution. But for now, you should check the
+    canary documents signed by biergaizi and vimacs to decide the validity
+    of the canary documents. This effectively reduced the number of signers
+    to two people. It reduces the level of confidence, but currently there is
+    no alternative option yet.
+    c. Once the technical problem of using a public key without User-ID is
+    resolved, you can check the previous signatures retroactively, and this
+    would effectively restore the level of confidence. You can archive the
+    documents to your own machine as soon as it's published to ensure no data
+    tampering has occurred.
+. To verify vimacs' signature...
+    a. Due to the recent attacks on OpenPGP keyservers, vimacs has published
+    the OpenPGP public key to https://keys.openpgp.org, again, without a User-
+    ID. But it's possible for a 3rd-party to verify the signatures by following
+    these steps.
+    b. Use Debian GNU/Linux operating system and install GnuPG. Other operating
+    systems may lack the necessary out-of-tree GnuPG patches required, Debian
+    must be used.
+    c. Fetch vimacs' old public key from a traditional OpenPGP Keyserver, such
+    as https://keyserver.ubuntu.com, and import the public key. The fingerprint
+    is 0x7079B481F04B5D8B65A0ECDEEA2DB82FE04A9403. You should see an expired
+    public key.
+    d. Fetch vimacs' new public key from https://keys.openpgp.org, using the same
+    fingerprint, and import the public key. You should see that the public
+    key has been updated.
+    e. Please note that the key is still shown as "expired" because the new key
+    has no UID associated. But you should be able to see a new, valid (not
+    expired) subkey by...
+        $ gpg --list-options show-unusable-subkeys 	--list-keys 0x7079B481F04B5D8B65A0ECDEEA2DB82FE04A9403
+    f. Now, it's possible to verify the signature by following the standard
+    procedures. Ignore the "key expired" warning (because the latest UID is
+    not published, only the expired UIDs are available).
