The DateLoom plugin for RapidWeaver was discontinued in late 2017. The plugin is no longer for sale or being developed. However, as a courtesy to our customers, we have built a version that will work on macOS Catalina. You can download this version below.
Please be aware that this build only has Catalina security fixes. NO other changes were made. This build should be considered as is. I recommend looking for another product going forward, but at least this gives users time to do so.
