This release introduces build-on-release from the com9MoTVoellmy module via automatic source download . It also brings several com1DFA fixes, including a memory corruption bug affecting com5SnowSlide, plus new features for selective particle property saving and improved time-dependent release handling. Additionally, com4FlowPy now computes per-cell startCellID and output polygons, com6RockAvalanche fixes a negative-value bug in scarp.py and exposes more configurable parameters, in2Trans gains raster-to-NetCDF conversion utilities, documentation is updated with clearer time-stepping docs and an AI usage guide, and cfgUtils now correctly handles "none" strings in numeric checks. com9MotVoellmy This release introduces a build on release for com9MoTVoellmy: Build-on-install: The C binary is compiled at release generation or on demand within the repository, with source fetched automatically from the latest upstream GitHub release. No precompiled binaries are shipped in the repository. Upstream version: Includes MoT-Voellmy v2026-05-04, which fixes bugs in the AvaFrame-entrainment model (entrainment energy now correctly read from file). com1DFA Fix arrays returned by updateFieldsC to be properly owned copies, preventing memory corruption across Cython calls. This fixes a long-standing bug in com5SnowSlide. Selective particle property saving: configure which particle properties to save, reducing output file sizes. Centralized particle property definitions, extracted into a shared helper function. Time-dependent release improvements: Support multiple time-dependent release files for parallel simulations. Support more release features with time-dependent release. com4FlowPy Compute startCellID per cell and produce output polygons for each process path. Remove release volume min/max output option. com6RockAvalanche Fix scarp.py to disallow negative values in generated raster files. Expand com6RockAvalancheCfg.ini with all adjustable parameters. in2Trans Add rasterUtils functions to convert rasters to NetCDF files. Documentation Clarify time-stepping configuration in com1DFA docs and config file (fixes #1285). Add LLM/AI usage section to the developer guide.
