- Uses Parsl >= 1.0.0
- Adds a flag `--no-xyz` for any boolean option xyz (to match the existing `--xyz` flag
- Adds a flag `--memmon N` to print available memory every N seconds
- Preliminary CC-IN2P3 support
- Uses newer versions of Parsl and makes the version number more flexible.

Version 1.1 adds the python_paths feature, which adds to the PYTHONPATH variable for both the pipeline manager and any jobs launched.
