Recent release of PyRFA 8.0.0 (and forward) has dropped support for 32-bit and RHEL5. It supports only 64-bit systems on both Windows and Linux. The reason to drop the support on 32-bit depends on Thomson Reuters RFA C++ libraries that we use to build PyRFA. And since Thomson Reuters has decided not to include the libraries, PyRFA is affected this way.
Feature-wise, we will keep maintaining version 7.6.1 as it is the last version with 32-bit and RHEL5 support. All future bug fixes and enhancement made to 8.0.0 will also be ported back to 7.6.1.
For this case, 220.127.116.11 releases also change the data output format into a pure dictionary just like in 8.0.0.
Thanks for using PyRFA!
