<div dir="ltr"><div class="gmail_quote"><div dir="ltr">Hi all,<div><br></div><div>I have noticed that old models don't work in the new processing modeler. This is really, really bad. Breaking a format is just as bad, or even worse, as breaking a API. Users don't care (much) for APIs but they care about formats and when they stop working people get annoyed.</div>
<div><br></div><div>Processing is a core plugin and therefore people consider it part of QGIS, changes in it effect us as a whole product. If I break one of my plugins that hurts me, if I change a core format (e.g qgs, qlr) that hurts the whole QGIS project.</div>
<div><br></div><div>I can understand the need to move forward to something better, and the new JSON format is much better then a custom format I will never argue for the later. However not providing a way to import old models, or even doing it by auto magic, is really bad. </div>
<div><br></div><div>Some people invest a lot of time into creating models for processing and having it break under them with no option but to recreate will leave a bad taste with people, trust me on that. As processing has been "core" since 2.0 you can expect a lot of models in the wild and a lot of annoyed people if there is no option to upgrade.</div>
<div><br></div><div>What I am NOT proposing is to revert that work, we do need to move forward but I do think there needs to be a conversion function/s. </div><div><br></div><div>However if it comes close to release and there is no conversion ability then I would say we should revert the plugin in core and wait for the next release to upgrade the models. Breaking the models on people with no convert option will have much more effect then not having some of the new features.</div>
