v2.21.0

New Features

• voice: a second screen share engine, Smooth Video. Chromium's capture gives up at
  around 0.2 fps once a game has the graphics card to itself; this one captures and encodes on
  the card and holds its framerate through the game. The share dialog picks between it and
  Sharp Video, the old path, which is still what you want for text and code. Windows only —
  and where it cannot run, the share falls back to sharp on its own
• voice: the game you are playing is offered right above the voice controls — its icon, its
  name, and one click to share that window without going through the picker
• ios: tapping an mqvi.net invite or channel link opens the app instead of the browser, and
  a DM notification is pulled back off the lock screen once you read the conversation on
  another device

Bug Fixes

• voice: sharing a single window sent everything the machine was playing — the film in the
  next window came through with the game. A window now contributes only its own sound, while a
  shared monitor still carries everything except mqvi itself

Other Changes

• desktop: Electron 33 → 42 (Chromium 130 → 148), picking up about a year and a half of
  security and platform fixes
