 # Changelog
 
+## v0.7.0
+
+### Text styling
+
+- **Rich text rendering** -- messages with Signal formatting now display with
+  proper styling: **bold**, *italic*, ~~strikethrough~~, `monospace`, and spoiler
+  text. Spoiler content is hidden behind block characters (closes #66)
+
+### Sticker messages
+
+- **Sticker display** -- incoming stickers are now shown as `[Sticker: emoji]`
+  in the chat area instead of being silently dropped (closes #67)
+
+### View-once messages
+
+- **View-once handling** -- view-once messages display as `[View-once message]`
+  with attachments suppressed, respecting the ephemeral intent (closes #68)
+
+### Cross-device read sync
+
+- **Read state sync** -- when you read messages on your phone or another linked
+  device, signal-tui marks those conversations as read and updates unread counts
+  automatically (closes #71)
+
+### System messages
+
+- **Missed calls** -- missed voice and video calls now show as system messages
+- **Safety number changes** -- a warning appears when a contact's safety number
+  changes
+- **Group updates** -- group metadata changes (member adds/removes) display as
+  system messages
+- **Disappearing message timer** -- changes to the expiration timer show a
+  human-readable message (e.g. "Disappearing messages set to 1 day")
+
+### Message action menu
+
+- **Enter key menu** -- press Enter in Normal mode on a focused message to open
+  a contextual action menu. Available actions (shown with key hints): Reply (q),
+  Edit (e), React (r), Copy (y), Delete (d). Navigate with j/k, press Enter to
+  execute, or use the shortcut key directly (closes #85)
+
+### Bug fixes
+
+- **"New messages" bar** -- the unread separator no longer persists after viewing
+  a conversation with new messages (#90)

+- **Italic** -- displayed with terminal italic
+- **Strikethrough** -- displayed with terminal strikethrough

 ## Read receipts
 
 signal-tui sends read receipts to message senders when you view a conversation,
 letting them know you've read their messages. This can be toggled off via
 `/settings` > "Send read receipts".
 
+## Cross-device read sync
+
+When you read messages on your phone or another linked device, signal-tui
+receives the read sync and marks those conversations as read. Unread counts
+update automatically.
