Update to v2.12.1

- Fix bugs related to capping the sizes of caches - Capping a cache to `0` bytes would not completely disable it as documented, fixed - Setting the max ratio value to a negative value would not use the default value as documented, fixed - Thanks to @jml5qh for filing this issue (#41) - Analyzer warning fixes too (not actual bugs)
