3.3.1

[3.3.1] - 2026-08-21

Fixed

• Message composer: Up/Down (and Shift+Up/Shift+Down, wheel
  scrolling) now move by display row in soft-wrapped text, keeping the
  x position in cells, instead of jumping by logical line.

Changed

• Release package files are now uniformly named
  wtmux-<version>-<os>-<arch> (e.g. wtmux-3.3.1-windows-x64.exe
  / .zip / .msi, wtmux-3.3.1-linux-amd64.deb).
• Packaging scripts gained a -Sign option that code-signs the bundled
  executable, the Inno Setup installer and its uninstaller, and the MSI;
  the new build-release-packages.ps1 builds all Windows packages in
  one go. The manual install.ps1 was removed.
