Messages arriving while a conversation was open were never marked as read,
so the chat list kept showing them as unread after going back. The screen
now marks incoming messages read while it is on top and the app is in the
foreground, again when the app returns to the foreground, and on leaving.
Read state is now monotonic in Conversation.updateMessage, so a stale copy
of a message (attachment download, delayed resend) can no longer flip it
back to unread.
Also create the swipe-to-reply animation controller lazily instead of in
dispose().
A new look across the app and a set of everyday messaging features.
Interface
- Home screen with Chats, Contacts and Settings tabs, a large title,
search across chats and message text (diacritics-insensitive), filters
and pinned chats.
- Conversation view with a translucent header and composer, grouped
bubbles, author avatars and colours in groups, swipe to reply, an
"N new messages" marker, a jump-to-latest button and in-chat search.
- Contact and group profiles: verification, shared photos, groups in
common, disappearing messages, mute, block; members, admin badges,
adding people, rename and leave for groups.
- Full-screen photo viewer that pages through the whole conversation.
- A stable avatar colour per person and a clearly visible read state.
Messaging
- Polls in chats and groups, single or multiple choice, with votes that
can be changed or withdrawn; older clients see them as text.
- Drafts survive leaving a chat and show in the chat list.
- Forwarding of messages, photos, files and voice messages.
- Notes to self: a local-only, encrypted chat that never reaches the
relay.
- @mentions in groups that notify even when the group is muted.
- Typing indicators sent as ephemeral messages, opt-in and mutual like
read receipts.
- Delivery and read times per message and per group member.
- Profile photos, cropped, resized and stripped of metadata, delivered
encrypted to contacts.
- Voice message playback at 1.5x and 2x.
- Call buttons in 1:1 chats and call log entries.
Fixes
- Muted groups no longer notify: muting was checked against the
author's chat instead of the group.
- A blocked contact could unblock itself by changing its delivery
address.
- Read receipts no longer regress to delivered when a late delivery
receipt arrives.
- A message marked as failed corrects itself once it is delivered.
- Double ticks in groups now mean delivered to every member.
A message sent into a dead socket ended up as failed — attachments even
stayed on "sending" forever — and only the user could send it again by
hand. Mobile NAT drops idle TCP silently, so neither side knew.
- pingInterval on the WebSocket, so the client notices a dead link itself
- outbox: after every reconnect, stuck messages are re-sent (batch of 30,
up to a day old); permanent errors are not retried
- sendAttachment gained the try/catch it was missing, otherwise the
attachment never reached the outbox
- de-duplicate by message id: a retry re-sends the SAME message, which
would otherwise show up twice on the other side
Initial public release. Anonymous on-device identity (no phone number,
e-mail, or password), Signal-protocol cryptography (X3DH + PQXDH, Double
Ratchet, sealed sender) via libsignal, a metadata-minimizing relay,
group chats, disappearing messages, encrypted local storage, optional
Tor transport, and a UI localized into Czech, English, German, Russian,
and Italian.
