matRad's 3.2.3 patch brings first support for oxygen ion planning, including generic base data and the MKM biological model. It further fixes a long-standing issue where range shifters did not produce lateral broadening in the analytical pencil-beam engines, introduces a versioned machine file format for photon base data with corrected kernel normalization, and updates Octave support (mex file management & builds for Octave >= 10). New Features & Enhancements Oxygen ion support: new oxygen_Generic base data, the MKM biological model (matRad_MKM / z*-based LQ models), and oxygen handling in the particle stf generators and pencil-beam engine. Range shifter lateral scattering (matRad_calcSigmaRashi) is now modeled for heavier ions (helium, carbon, oxygen) in addition to protons. Userfolders can now also be set via the environment variable MATRAD_USERDATA. New versioned machine file format: photons_Generic.mat base data now carries a version field alongside meta and data. Version 2 requires correct kernel normalization (without implying a spacing in the convolution integral); old files are treated as version 1 for backwards compatibility. Photon dose calculation (SVDPB) no longer relies on hardcoded convolution-resolution normalization of machine kernels (old kernels are assumed to use the hardcoded factor of 4 for 0.5 mm resolution). Bug Fixes Range shifter lateral scattering is now correctly applied to the lateral dose kernels of the analytical pencil-beam engines (HongPB, Anal...
