@@ -47,6 +47,10 @@ Hush enabled enforced privacy (z2z) at Block 3400000 in November 2020, directly
 This is enforced privacy at the blockchain level. Hush also has network-level privacy: Hush nodes use TLS 1.3
 to talk with eachother, not plaintext, like Bitcoin and Zcash.
 
+The original Hush source code had TLS implemented, and then when we migrated to KMD, that was lost. Finally,
+the developer `miodrag` wrote a new TLS 1.3 implementation and Hush now requires all nodes to use encrypted
+p2p connections as of Hush 3.6.1. This used to be called `-tls=only` (when TLS was optional) but now that option has no effect and the internals always enforce privacy.

 ## New Domain: hush.is
 
 Hush switched from myhush(.)org to [hush.is](https://hush.is) because some ex-community members stole and sold the domain in some good old-fashioned Internet Drama, documented [here](https://git.hush.is/hush/fraud/)
