@@ -294,27 +298,25 @@ What is already implemented:
 1. Instead of user profile identifiers used by all other platforms, even the most private ones, SimpleX uses [pairwise per-queue identifiers](./docs/GLOSSARY.md#pairwise-pseudonymous-identifier) (2 addresses for each unidirectional message queue, with an optional 3rd address for push notifications on iOS, 2 queues in each connection between the users). It makes observing the network graph on the application level more difficult, as for `n` users there can be up to `n * (n-1)` message queues.
 2. [End-to-end encryption](./docs/GLOSSARY.md#end-to-end-encryption) in each message queue using [NaCl cryptobox](https://nacl.cr.yp.to/box.html). This is added to allow redundancy in the future (passing each message via several servers), to avoid having the same ciphertext in different queues (that would only be visible to the attacker if TLS is compromised). The encryption keys used for this encryption are not rotated, instead we are planning to rotate the queues. Curve25519 keys are used for key negotiation.
 3. [Double ratchet](./docs/GLOSSARY.md#double-ratchet-algorithm) end-to-end encryption in each conversation between two users (or group members). This is the same algorithm that is used in Signal and many other messaging apps; it provides OTR messaging with [forward secrecy](./docs/GLOSSARY.md#forward-secrecy) (each message is encrypted by its own ephemeral key) and [break-in recovery](./docs/GLOSSARY.md#post-compromise-security) (the keys are frequently re-negotiated as part of the message exchange). Two pairs of Curve448 keys are used for the initial [key agreement](./docs/GLOSSARY.md#key-agreement-protocol), initiating party passes these keys via the connection link, accepting side - in the header of the confirmation message.
-4. [Post-quantum resistant key exchange](./docs/GLOSSARY.md#post-quantum-cryptography) in double ratchet protocol *on every ratchet step*. Read more in [this post](./blog/20240314-simplex-chat-v5-6-quantum-resistance-signal-double-ratchet-algorithm.md) and also see this [publication by Apple]( https://security.apple.com/blog/imessage-pq3/) explaining the need for post-quantum key rotation.

To protect your IP address from unknown messaging relays, and for per-message transport anonymity (compared with Tor/VPN per-connection anonymity), from v6.0 all SimpleX Chat clients use private message routing by default.

 We plan to add:
 
-1. Automatic message queue rotation and redundancy. Currently the queues created between two users are used until the queue is manually changed by the user or contact is deleted. We are planning to add automatic queue rotation to make these identifiers temporary and rotate based on some schedule TBC (e.g., every X messages, or every X hours/days).
+1. Senders' SMP relays and recipients' XFTP relays to reduce traffic and conceal IP addresses from the relays chosen, and potentially controlled, by another party.
-2. Message "mixing" - adding latency to message delivery, to protect against traffic correlation by message time.
+2. Post-quantum resistant key exchange in double ratchet protocol.
-3. Reproducible builds – this is the limitation of the development stack, but we will be investing into solving this problem. Users can still build all applications and services from the source code.
+3. Automatic message queue rotation and redundancy. Currently the queues created between two users are used until the queue is manually changed by the user or contact is deleted. We are planning to add automatic queue rotation to make these identifiers temporary and rotate based on some schedule TBC (e.g., every X messages, or every X hours/days).

 SimpleX Chat is still a relatively early stage platform (the mobile apps were released in March 2022), so you may discover some bugs and missing features. We would really appreciate if you let us know anything that needs to be fixed or improved.
