ABOUT PyDDE

PyDDE is an open source numerical solver for systems of delay differential equations (DDEs), implemented as a Python package and written in both Python and C. It is built around the numerical routines of the R package ddesolve, which is itself based on Simon Wood's Solv95, a DDE solver for Microsoft Windows systems written in C.

RELEASE NOTES

0.2.2_2to3 - 21 December 2011

-- Patched 0.2.2 for python3 (patch via renato)

0.2.2 - 07 December 2008

-- Fixed a bug that resulted in failure to compile on some Mac OS X systems. (Thanks to Josh Lippai who reported the bug and coded the fix.) -- Various minor typographical corrections to the code and manual.

0.2.1 - 31 October 2007

-- Migrated to use the back-end from the R package 'ddesolve'.

0.1.3 - 25 April 2007

-- Fixed a memory 'leak' due to poor reference handling of Python objects in the C code. Python was keeping a reference to objects that should have been deleted. -- Fixed a segfault when updating or cleaning up the history buffer for models without any history variables. -- Fixed an apparent bug in setup.py. The libraries field doesn't work with some versions of Python. Removing it doesn't seem to hurt, either.

0.1.2 - 23 April 2007

-- Improved memory management by better allocating and freeing the simulated data and history buffer at each dde.solve() call.

0.1.1 - 13 April 2007

-- Fixed a bug whereby a data variable would be defined twice, causing compilation errors on some systems (e.g. OS X with gcc 4.0.1).

0.1.0 - 14 December 2005

-- First release of PyDDE.
