# parabola changes and rationale:
# libre:
#   - build without webengine (BR #1167)
#   - build without pip (BR #1035)
#   - disable downloader (BR #1035)
#   - add default session XML (BR #3522)
# technical:
#   - build from versioned source-ball rather than VCS sources
#   - pin to strongly-coupled dependency versions
