This patch release comes with a few new experimental memory metrics. Furthermore, it resolves an issue where the memory usage would grow without bounds on some systems.

We have switched the allocator back to the system allocator for now, as the mimalloc setup led to significant memory usage issues on some systems.

Furthermore, we added quite a few experimental memory-usage related metrics to metrics "memory", providing additional insight into the memory usage of Tenzir.
