Release 0.18.20 - Remove the Corpuscles dependency; neutrino PDG codes are now hardcoded. This also drops Unitful/UnitfulAtomic and eliminates load-time recompilation. - Move HDF5 into a package extension (KM3ioHDF5Ext). using KM3io no longer pulls in the HDF5/MPICH stack; HDF5 features now require `using HDF5`. - Add a PrecompileTools workload so the first ROOTFile open/read is ~2.4x faster. - Convert the Cherenkov-times docs example from PGFPlotsX to CairoMakie. - Add diff tools (compare, Diff, FieldChange, ...). - Fix aux test.
