# Example py8decayer History

See `CONTRIBUTING.rst` for details of **required** info/format for each entry,
which **must** added in reverse chronological order (newest at the top). It must **not**
be used as a substitute for writing good git commit messages!

## 2024-05-30 Julia Yarba (p8decayer-V11-03-00)
- Test vs Pythia8.3.15 which is the latest as of May 2025
