Hello Juha & Werner,
I see you disabled the new item format for project info files by default on Werner's request. I understand that the first version wasn't ideal - if you needed to open a project in 2.1 and 2.0/1.8 you always had to check the compatibility mode when opened in 2.1.
But the current version is not ideal either - most people do not open projects in legacy versions and they have to disable compatibility mode for every new project manually.
I came up with a reasonable solution:
1.) set CompatibilityMode automatically for legacy projects. 2.) disable CompatibilityMode for new projects.
That should be good for everybody - the CompatibilityMode flag doesn't get lost if you open&save a project in a legacy Lazarus version and new projects use the new format.
