We just upgraded the version of libapreq2 to 2.17. This caused an app that has been runing for 15 years to stop working.
We have a page with a multipart/form-data form that has a few file upload fields. These fields were showing up in the params list with libapreq2 v2.16 but now with libapreq2 v2.17 they and all the fields after them are not in the params list.
