LibreNostr v0.5.0

Added

• Tor support via Orbot: a new "Tor" entry in Settings routes relay
  connections, zap/lightning requests, media uploads, image loading, media
  downloads, video/audio playback, and embedded link previews through
  Orbot's SOCKS proxy instead of connecting directly. Off by default; the
  SOCKS port is configurable (defaults to Orbot's own default, 9050). If
  Orbot isn't detected as installed, the settings screen says so plainly.
  There is no fallback to a direct connection if the proxy isn't reachable
  — connections fail instead of silently leaking outside Tor. The setting
  takes effect on the next full restart, not immediately, since every
  network client in the app is a long-lived singleton built once at
  startup; the app is explicit about this rather than pretending otherwise.
  A new onboarding step (shown once, for both new and existing accounts)
  explains the feature and links to Orbot on Zapstore.

Fixed

• Tapping the zap button could crash the app outright. The zap sheet's
  amount-preset grid was a LazyVerticalGrid sitting inside a Column
  that scrolls to make room for the keyboard — a lazy grid inside a
  scrollable container with no bounded height is disallowed and threw
  immediately. Replaced with a plain, non-lazy grid; the preset count is
  small and fixed, so there was never anything to virtualize.
