Last version of ownCloud Android that uses file system

Now I’ve read quite a bit about the reasons why the ownCloud App does not store offline files anymore and I guess we’ll have to live with that.
Which brings me to a new question: which ownCloud Android App is the last version, that still stores local files and where can I get it?
I’ve looked on FDroid, but could not find any version older than 2.19 which is definitely not the version I need.
