# parabola changes and rationale:
#   - removed 'qt5-webengine' dependency
#   - set webkit backend as default
#   - condensed the excessive webkit rant on the welcome screen
#   - pin to strongly-coupled dependency versions


# NOTE: Arch has no QT webkit. Parabola retains 'qt5-webkit' primarily
#       to support 'qutebrowser'.
#       Qt5 and webkit are supported upstream; but that may change.
#       Watch https://github.com/qutebrowser/qutebrowser/issues/4039
#       especiallly, WRT movableink/webkit + mnutt/PyQt6-QtWebKit.


# NOTE: for each 'qt5-base' N.N.N release, build order:
#         (qt5-base-N.N.N) <- qt5-webkit <- python-pyqt5 <- qutebrowser
# NOTE: for each ''python N.N release, build order:
#         (python-N.N) <- python-pyqt5 <- qutebrowser
