+# SimpleX Chat v4.4 released – with disappearing messages, live messages, connection security verification and French language!
+
+**Published:** Jan 3, 2023
+
+## What's new in v4.4
+
+- [disappearing messages](#disappearing-messages).
+- ["live" messages](#live-messages).
+- [connection security verification](#connection-security-verification).
+- [animated images and stickers](#animated-images-and-stickers) – now on iOS too.
+
+Also, we added [French language interface](#french-language-interface), thanks to the users' community and Weblate!
+
+### Disappearing messages
+
+<img src="./images/20230103-disappearing1.png" width="288"> &nbsp;&nbsp; <img src="./images/20230103-disappearing2.png" width="288">
+
+It is now possible to send the messages that will be deleted from both sender and recipient device after set time – for the sender from the time they were sent, and for the recipient - from the time they were read.
+
+Unlike in most other messengers, it requires agreement of both sides, not just the sender decision. I [wrote previously](./20221206-simplex-chat-v4.3-voice-messages.md#irreversible-message-deletion) why we believe it is wrong to allow the senders to delete their messages without recipient consent, and the same logic applies here – if you want to send the message that will disappear after some time, your contact should be ok with that too.
+
+In group conversations disappearing messages can be enabled by the group owners, by default they are disabled.
+
+### "Live" messages
+
+<img src="./images/20230103-live.png" width="288">
+
+Pressing "bolt" button before you start typing the message will start a "live" message. Now, as you type it, it will be updated for all recipients every several seconds, including only complete words. To finish the message you need to press "checkmark" button.
+
+You can also start a live message after you started typing or after you chose the image – long-press send button and then press "Send live message".
+
+### Connection security verification
+
+<img src="./images/20230103-verification.png" width="288">
+
+SimpleX Chat design prevents the possibility of messaging servers substituting the key during the initial connection (man-in-the-middle attack) by requiring that the invitation link is passed via another channel. I wrote more about how MITM attack works in [this post](https://www.poberezkin.com/posts/2022-12-07-why-privacy-needs-to-be-redefined.html). But this other channel, however unlikely, could still have been compromised by an attacker to replace the invitation link you sent. That is the reason why we recommend sharing QR code in a video call – this is very complex for an attacker to replace it in this case.
+
+This new feature allows you to verify, via yet another channel, that the connection is secure and the keys were not replaced. You can either scan the security code from your contact's app, or compare codes visually, or even read it in a voice call – if your and your contact's app have the same security code for each other then the connection is secure.
+
+If you are sending direct messages to some group members then it might also be important to verify security of these connections, as in this case the invitations were exchanged via the member who added you or another member, and if this member's client was modified, they could have replaced the keys and the addresses, and intercept the entire conversation.
+
+Regardless how connection is established, verifying the connection proves its security. Technically, this security code is the hash of associated data used in the end-to-end encryption, which in turn is taken by combining public keys from the initial key exchange.
+
+### Animated images and stickers
+
+<img src="./images/20230103-stickers1.png" width="288"> &nbsp;&nbsp; <img src="./images/20230103-stickers2.png" width="303">
+
+Android app supported GIFs and stickers for some time, now you can view and send them from iOS app as well, e.g. using GIPHY keyboard - you no longer need to choose between privacy and stickers. Just bear in mind, that third party keyboards can be insecure, so you should not be using them for typing sensitive information.
+
+### French language interface
+
+Thanks to our users' community and to [Weblate](https://weblate.org/en-gb/) kindly providing a free hosting plan for SimpleX Chat translations we can now support more languages in the interface – this version adds French.
+
+Please get in touch if you want to translate the interface into your language!
+
+## SimpleX platform
+
+Some links to answer the most common questions:
+
+[How can SimpleX deliver messages without user identifiers](./20220511-simplex-chat-v2-images-files.md#the-first-messaging-platform-without-user-identifiers).
+
+[What are the risks to have identifiers assigned to the users](./20220711-simplex-chat-v3-released-ios-notifications-audio-video-calls-database-export-import-protocol-improvements.md#why-having-users-identifiers-is-bad-for-the-users).

+
+## Help us with donations
+
+Huge thank you to everybody who donated to SimpleX Chat!
+
+We are prioritizing users privacy and security - it would be impossible without your support.
+
+Our pledge to our users is that SimpleX protocols are and will remain open, and in public domain, - so anybody can build the future implementations of the clients and the servers. We are building SimpleX platform based on the same principles as email and web, but much more private and secure.
+
+Your donations help us raise more funds – any amount, even the price of the cup of coffee, makes a big difference for us.
+
+It is possible to donate via:
+

+# User profiles
+
+## Problem
+
+Convenience of having different communication contexts in a single client without shared metadata.
+
+Currently requires changing chat database and restarting chat.
+
+Events (notifications) for databases other than current are not received.
+
+## Solution
+
+Support for multiple user profiles in a single database.
+
+Separate transport connections with the same servers not shared between profiles.
+
+## Design
+
+### API
+
+- new users are created using existing CreateActiveUser API
+
+- APIListUsers
+
+- APISetActiveUser UserId
+
+- CRUsersList {users :: [User]}
+
+- terminal APIs
+
+### Subscriptions
+
+- get connections for all users, subscribe to all - to receive events for users other than active
+
+- map subscriptions to users?
+
+- option to subscribe to connections for only one user? `StartChat {allUsers :: Bool}` API
+
+- if more than one user profiles - start with last active user (persist?), or always load list of users first and wait for choice? same for terminal?
+
+### Chat items expiration
+
+- store supports this configuration per user
+
+- expire chat items for all users with different ttl
+
+  - in `runExpireCIs` get list of users, for each - `getChatItemTTL` and run `expireChatItems`
+
+### Disappearing messages
+
+- `cleanupManager` - remove parameterization by User
+
+- either `getTimedItems` and start deletion threads for all users, or similar to expiration get list of users and run `cleanupTimedItems` per user
+
+### Events
+
+- events need to have information for which user they happened
+
+  ```haskell
+  data UserChatResponse = UserChatResponse
+    { user :: User,
+      chatResponse :: ChatResponse
+    }
+  ```
+
+- replace ChatResponse with UserChatResponse in APIResponse, toView, etc.
+
+- in `agentSubscriber` don't get currentUser from controller, instead either:
+
+  - get user from database by agent connection id
+
+  - get from subscriptions user-connections map - either requires scan or keys and values have to be inverted, also key would have to be agent connection id not database connection id - probably easier/better to read from db
+
+- non active user profile can be shown in notifications
+
+- interactions via notifications - prohibit for simplicity? or change APIs to allow specifying User?
+
+- changes to chat model are applied only for current user
+
+### ChatController
+
+- currentCalls:
+
+  - change `currentCalls` key? `currentCalls :: TMap (UserId, ContactId) Call`
+
+  - `restoreCalls` - for all users?
+
+  - interaction via notification - prohibit for non active user? change current user before accepting?
+
+- `incognitoMode` - save setting or share between users?
+
+- when changing active user reset `activeTo`?
+
+- in `newChatController` when creating smpAgent - `getSMPServers` have to get servers for all users, or depending on allUsers flag in StartChat; // drop known_servers table?
+
+- `AgentConfig` should depend on network configuration per user?
+
+- double check other state
+
+### Storage
+
+- schema already has support for multiple users
+
+- persist last active user?
+
+- persist user settings? (see below)
+
+### Frontend
+
+- view with list of user profiles available from settings, change active user from there
+
+- do we need additional information in that view? for example, number of unread messages
+
+- network configuration is stored in app preferences - if unchanged will be the same across users
+
+  - persist in database per user and load?
+
+  - different configuration across platforms
+
+  - save network settings in separate preference for each user as json? dynamic preferences or predefined number of users?
+
+- same for other settings - auto-accept images, send link previews, etc.
+
+### Terminal view
+
+- for users other than active view responses to have indication that it's for a different user profile, e.g. `[<user_name>]`, `[user: <user_name>]`
+
+- don't set `activeTo` for non active user profiles
+
+- only way to reply to a message in other user profile is to manually switch current active user first?
