 We've had a funding shortfall recently -- we'd really appreciate it if you [[https://github.com/sponsors/FolkComputer|sponsor Folk on GitHub Sponsors]] if you can, so that we can keep doing this free and open work :-)

 === Memory leak ===
+Because I've been trying to run folk2 on the (RAM-constrained) gadget, I've been really wanting to fix the memory leaks in it. It's been tough. My hypothesis (from seeing Jim allocations get out of control and from manually inspecting the heap) is that it's mostly little Jim Tcl heap objects (Jim_Objs, mostly). But hard to trace causation beyond that point so far.

 For now, I guess we'll try to merge folk2 without even the cache, just string reparsing every block, and then later see if some of these other approaches can be revived and can help further.
