v2025.10

Version of SWIFT from October 2025.

Major changes since v2025.04:
 - Memory-lean implementation of FOF,
 - Added extra properties to the FOF catalogs (halo radii, stellar mass, gas mass, SFR),
 -  Reduced the memory footprint of the foreign `gpart`,
 - Fix rounding error bug in calculation of number of top-level cells,
 - Many small bug fixes

v2025.04

Version of SWIFT from April 2025.

Major changes since v2025.01:
 - Updated neighbour finding performing operations at different level in the tree to speed up operations in deep hierarchies with steep density gradients (backport from COLIBRE fork)
 - REMIX-SPH included as a hydrodynamics scheme.
 - Added more equations of state for planetary applications.
 - Added an interface to Lustre such that the code can stripe files cleverly based on the properties of the filesystem it runs on.
 - Many small bug fixes

This version is nearly identical to the base version used for the large COLIBRE production runs.
 - Many updates to the GEAR model.

v2025.01

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.
