Compatibility of Parse 1.5.0 client SDK

tl;dr What’s the latest version of parse-server with a REST API compatible with the Parse Javascript SDK version 1.5.0?

I have an ancient application that I wrote right before the original parse.com switched from Backbone to React. It is still a Backbone app using the Parse 1.5.0 JavaScript SDK that was last released before the switchover. I don’t have much interest in making major changes to this code as this project is mostly just in maintenance mode, but MongoDB marches ever forward.

I’m interested if anybody knows if the latest parse-server still has anything resembling compatibility with the REST API used by Parse 1.5.0. The latest version of parse-server I’ve updated to is 2.8.4 and a lot seems to have changed since then.

Did you take a look at the compatibility table in the readme?

Hi @gnu-lorien. Did you have luck with this? We are in the same boat. Mongo is about to force an upgrade, and legacy GCM is shutting down. According to the compatibility chart, server <= 6 is compatible with SDK < 4, and our client is at 1.3. Just wondering if you ran into any issues, as we are working to spin up a server, but unfortunately our client was built with software that is no longer available, so we can’t even point it at the staging server to test at this point.
