pitivi: project file incompatibility between release versions

Question

I'm on Ubuntu 18.04, and 've been using pitivi from the standard repo ... version 0.99-3.

I want to start using the flatpak version of pitivi with some rather complicated video projects of mine, but my existing project files are not compatible. The flatpak version I want to use is the one labeled "latest release" on this page ... http://developer.pitivi.org/Install_with_flatpak.html?gi-language=undefined

My current Ubuntu version of pitivi creates project files with this header ...

<ges version='0.4'>

However, the latest flatpak version of pitivi seems to be older, and it produces project files with this header ...

<ges version='0.3'>

If I try to import my existing GES version 0.4 project files into the flatpak version of pitivi, I always get this error ...

Unable to load project "Project1.xges"

This might be due to a bug or an unsupported project file format. If you were trying to add a media file to your project, use the "Import" button instead.

I have tried changing all occurrences of "0.4" to "0.3" in my project files, but I still get the same error. There apparently have been syntax changes between 0.3 and 0.4 project file formats.

Does anyone know how to turn a GES 0.4 project file into one that is readable via GES 0.3? I don't want to have to re-create all these existing projects, just to be able to use the flatpak version of pitivi.

Thank you in advance.

I got it working with the "1.0 Development Snapshot" at the same site that I mentioned above.

I had tried that Development Snapshot before, and it didn't work. But then, I uninstalled pitivi and flatpak, reinstalled flatpak, and then installed the pitivi flatpak distribution like this ...

$ flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
$ flatpak install flathub org.gnome.Platform//3.34
$ flatpak install http://flatpak.pitivi.org/pitivi.flatpakref

Then, my 0.4 project files started being readable.
