v2.2.0

• Updates to the Photoelectron file format and IO classes
• Add method for saving and loading a Camera object via pickle
• Add method to reinitialise pixel mapping to change n_pixels
• Moved Photoelectrons class outside of the event module
• Refactoring of ReferencePulse into PhotoelectronPulse (with deprecation cycle)
• Altered approach of SPESpectrum classes, to handle their own probability sampling
• Created the SiPMPromt and SiPMDelayes SPESpectrum classes, which add additional photoelectrons to simulate the opct behaviour
• Created the ACFilterCoupling and ACOffsetCoupling classes

v2.1.0

• Created the PhotoelectronReader to read files containing photoelectrons sourced elsewhere (e.g. corsika+simtelarray)
• Added the ability to attach metadata to a Photoelectrons object
• Bumped minimum ctapipe version to v0.8.0
• Separated the electronic noise component into one each for readout and digitisation. Both take the same ElectronicNoise class
• Improved trigger logic to use a fixed trigger signal length (more realistic)

v2.0.0

• Corrected waveform sampling to result in correct units (accounting for sampling rate)
• Created schematic diagram
• Refactored mapping into a single class, containing multiple CameraCoordinate classes
• Created Trigger class, allowing the selection of different trigger logics at runtime

v1.0.0

First release, providing full pipeline simulation with simple camera descriptions.
