SUMMARY I created 5 projects last week, with kdenlive-19.04.2-39137f4-x86_64.appimage version. Today I downloaded kdenlive-19.04.3-x86_64.appimage and when I try to load any of mentioned projects, kdenlive 19.04.2 shows an error "This project type is unsupported (version 0.99) and cannot be loaded. Please consider upgrading your Kdenlive version.". However, I can load projects not saved with kdenlive-19.04.2-39137f4-x86_64.appimage STEPS TO REPRODUCE 1. Save a project with kdenlive-19.04.2-39137f4-x86_64.appimage version 2. Try to load that project with kdenlive-19.04.3-x86_64.appimage version OBSERVED RESULT A window showing "This project type is unsupported (version 0.99) and cannot be loaded. Please consider upgrading your Kdenlive version." EXPECTED RESULT To load the project without issues. SOFTWARE/OS VERSIONS OpenSUSE 15.0 64bits KDE Plasma Version: 5.12.8 KDE Frameworks 5.51.0 Qt 5.12.4 (built against 5.12.4) The xcb windowing system ADDITIONAL INFORMATION I tried to load with nightly version kdenlive-19.07.70-b901b42-x86_64.appimage and it worked fine, but I would like to use the latest stable version to avoid again this problem.
Where did you get the AppImage "kdenlive-19.04.2-39137f4-x86_64.appimage" ? If it was downloaded from binary-factory.kde.org, it was probably a naming mistake, and the AppImage was in fact using git master - binary-factory always compiles git master. Good news is that 19.08 will be released very soon (rc should be published friday)
I can't locate the URL from where I downloaded the mentioned version. Anyway, thank you for your news. I'll wait to try the new version.
