 Startup and hybrid runs no longer run the 0th time step, consistent with the same change in CAM. (Branch and continue runs never had this 0th time step.) This means you will not get an extraneous initial history file anymore. In some circumstances this may also affect the names of history files.
 
-In most cases, the history “time” variable is now defined as the middle of a history file’s `time_bounds` instead of the end, for consistency with the same change in CAM. The exception is if you specify `hist_avgflag_pertape = 'I'` for that file, in which case it will be treated as an “instantaneous” file. Instantaneous history files (a) have their `time` coordinate set to the end of the last timestep (as did all history files before this tag) and (b) do not include `time_bounds`.

 The history dimension name `hist_interval` (of output variable `time_bounds`) is standardized to be `nbnd`. History variables `time_bounds`, `mcdate`, `mcsec`, `mdcur`, and `mscur` are standardized to include the calendar attribute.
 
 ### New surface datasets and landuse timeseries files ([PR \#2500](https://github.com/ESCOMP/CTSM/pull/2500))
 
 * Transient landuse timeseries files going back to 1700 now possible (and made for f09).  
-* Fix an important bug on soil fields that was there since `ctsm5.2.0`. This has the side effect of `mksurfdata_esmf` now giving identical answers with a change in number of processors, as it should ([issue \#2744](https://github.com/ESCOMP/CTSM/issues/2744))  
-* Surface datasets now provided for the `ne0np4.POLARCAP.ne30x4` grid ([PR \#2716](https://github.com/ESCOMP/CTSM/pull/2716), [issue \#2720](https://github.com/ESCOMP/CTSM/issues/2720))  
-* Surface datasets now have their version number embedded to prevent mismatch of surface dataset and CTSM version ([issue \#2723](https://github.com/ESCOMP/CTSM/issues/2723))

-  * PFT/LAI/soil-color raw datasets; now from the TRENDY2024 timeseries that ends in 2023\. (Issues [\#2570](https://github.com/ESCOMP/CTSM/issues/2570) and [\#2452](https://github.com/ESCOMP/CTSM/issues/2452))

 Note: Dust emissions in CTSM 5.3 will be different from the above simulations because of a tuning update that came in after those.
