Recently the new splash screen pbsplash was merged to edge, which besides fancy looks allows to set text on the splash screen dynamically instead of generating it ahead of time. This means going forward we don't need to regenerate all device packages anymore after changing a splash screen string, and it makes it possible to translate the messages in the future.
After merging, we had regressions on various UIs/devices. A fixup release was already made and merged, but some issues are not resolved yet.
See pmaports issue tracker for details. Please extend the issues if you have more useful information to contribute, or start a new issue if you notice a regression for which we don't have one yet.
