Downloads: The latest downloads include version 1.8.8 for x86 64-bit version of the application for Windows (7-10) and MacOS (10.10-10.15 Catalina) and version 1.8.9 which is a universal binary x86/arm64 version for MacOS (11.1 Big Sur) on both Intel and M1 Macs. The various support files used by both versions are interchangeable but the installation methods are now different. NOTE: for now, you will need to manually backup your database and any other support files that you have customized if they are located in the TDF_Plan folder before installing any new version of TDF_Plan. After installing a new version, copy those backed-up support files into the new TDF_Plan folder to overwrite the installation defaults. TDF_Plan now allows you to work from a remote copy of the support files which you can store in a preferred data folder located somewhere other than in the application folder in order to simplify future installation updates.
