Node.js before 5.2.0 can't load 5.2.0 tiddlers?

I’m always letting my node tiddlywiki linger a few versions back. It appears that if I try to load a 5.2.0 file with a 5.1.23 node tiddlywiki I always get a “no tiddlers” message.

Is this to be expected?

Yes, TiddlyWiki releases prior to v5.2.0 cannot see the new tiddler store area. Files saved in v5.2.0 and above include an empty store area in the old format, which is what prior versions will see.
