Version of SWIFT from January 2025. Major changes since v1.0.0: - Removed `engine_marktasks()` and the duplicated task unskipping infrastructure. - Added the option to use adaptive softening for some flavours of the hydro. - Added more physics to the sink particles, including an adaptive smoothing length (search radius). - Added more examples using sink particles. - Updated the configuration scripts to select good compiler options with Intel OneAPI. - Added the option for the star formation models to spawn >1 star particle per star formation event (super-sampling). This can be switched on in the EAGLE model. - Reduced the number of communications of end-of-step messages and replaced them by a all-reduce. - Added the option to run GEAR-RT on top of SPHENIX SPH. - Many updates to the AGN spin-jet model (See the Husko+2024 paper for details) - Many updates to the GEAR model.
