+## HD Model Version 5.2.4, 11 March 2025
+
+### Added
++ For coupled modeling using YAC, the script ./autogen.sh is added. The configure script is automatically generated and should not be edited manually. Please, use this new script to update configure when you change ./configure.ac or anything inside ./build-aux/m4.
++ Implement optional setting of start and end times and related nstep calculation to allow a simulation for a specific number of subdaily time steps. The HD offline scripts have also been adapted for running only a few days (IWORK=5) or using subdaily timesteps with daily forcing. For the steering of these offline runs, a sub-script ./scr/hd_subdaily_settings.ksh has been introduced.  
++ Implement the possibility of a dedicated restart writing at a specified time step.
++ Implement an option to periodically restart file writing on a monthly or annual basis.
+	
+### Changed
++ The MO_YAC_FINTERFACE is deprecated starting YAC 3.2.0 and will be removed in one of the next ICON releases. The configure script and the code is updated to use the new YAC module.
++ Regenerate configure script, which drops several manually introduced lines.
+
+### Fixed
++ Correct date/time global attributes in restart file at simulation end.
