Kallisti v0.9.3

• Personal emoji: keep your own emoji, collect them from messages with "Add to my emoji", everyone sees them
• Log in, register and link your account with a fediverse account (Mastodon, Pleroma/Akkoma, GoToSocial, …); your avatar comes along
• Several devices at once: one has voice, the others stay in the chat with "Join voice here"; unread state follows across devices
• Threads, text channel categories, channel moderators and voice subchannels
• Picture previews and video posters in the chat; download buttons save files
• Mentions of known users show as pills; spoilers can be hidden again
• A refresh keeps your channel, thread, voice channel, and mute and deafen state
• Drafts and picked attachments survive reconnects; an attachment stays until the server confirms its message, and is never sent twice
• Steadier streams: a playout buffer for watched streams, no join and leave sounds
• Desktop: links open in the system browser; videos play on Linux; macOS stays connected in the background
• Phones: Android keeps voice in the background; the member list opens without a jump
• Many fixes from two code reviews: permissions, bans across all of an account's devices, password changes end Mumble logins, resource limits

Kallisti v0.9.2

• Linux: voice works in the AppImage (GStreamer bundled, microphone permission, Opus fallback); no more hangs when opening Settings or joining voice; less memory use
• Native notifications on all platforms (Linux: app icon and an "Open" button)
• Paste images from the clipboard on Linux
• Smoother start in voice: avatars load separately, music gets a larger buffer at once
• One "Go live" button: screen, camera, or streaming from OBS
• Playback buffer setting, join and leave sounds, camera streams with quality choice
• Direct messages: right-click to pin, close, mute or mark as read
• Long messages fold; private channels show who can read them
• Send button on touch screens
