Dear all who are interested in pypar or parallel programming with Python. I have released a new pypar version (2.1.0_49). It incorporates - Race-condition patch from Jim Bosch - Functionality and demo for Bsend by C Makassikis - Deprecated obsolete functions - Migrated Mandelbrot demos to numpy - Fixed demo3.py for version 2 thanks to Felix Richter I also verified that all tests and demos work on a Linux 32 bit platform. Thanks to everyone for all the contributions and looking forward to hearing how it goes. Best regards Ole Nielsen Canberra, Australia
