What's new in 1.2.0: • Voice Effects — fun pitch-shift presets for voice messages. • Recall your own burn-after-read messages — tap or long-press your own burn message to recall, within the same 2-minute window as regular messages. • Burn-after-read picker now explains the rules — the recipient's countdown starts when they tap to open, and any unopened message auto-burns 36 hours after delivery. • Multi-select copy — select multiple chat messages and copy them all at once (burn-after-read excluded for safety). • Faster delete — long-press a message and tap "Delete" right in the menu; no longer hidden behind multi-select mode. • Clear chat history — wipe a private chat (chat menu ⋮ → Clear) or a group chat (Group settings → Clear chat history) to free up space locally; the other side's copy is not affected. • File previews — file size shown in the chat bubble before download; oversized files (> 100 MB) now caught at the picker, not after upload starts. • Tap the Messages tab again to jump to the first unread chat (or back to top when nothing is unread). Reliability: • Group message sync improvements — smoother catch-up when rejoining an active group after being offline. • Group Polls list no longer crashes when opened. • Desktop: Esc now closes fullscreen video. • Stability and privacy improvements.
