Another aspect to consider is the implementation of `__getitem__`: https://github.com/OceanParcels/Parcels/blob/d4fdc01e9913db51dd18e4eb1afcf2e6c8250b02/parcels/particle.py#L141-L143 See also https://github.com/OceanParcels/Parcels/pull/2122#discussion_r2285507966

Note that https://github.com/OceanParcels/Parcels/pull/2199#issuecomment-3285145938 now has a minimal breaking example

OK, so I dived deep into this KernelParticle Issue, and I think I fixed it. The minimal example above is actually quite easy to fix: ```diff def __getitem__(self, index): -...

@VeckoTheGecko and I just had a f2f discussion, and we decided to (at least temporarily) implement a fourth option: 4. Keep datetime64/timedelta64 in the pset.execute and kernel loop, but use...

Another complication is that we may want to use `particle.time` in its original `datetime64`/`timedelta64` format in the Interpolators (see #2081), so that option 4 above (cusing float iniside the Kernels)...

I'd vote for a bit of a mixture between the first and the second. So have a migration guide, have the documentation just focussed on v4 _and_ have (temporary) info...

I feel just `verbose=True` is too vague for new users. I see the progress bar as a form of logging, so in my mind `verbose_logging` encapsulates the progress bar, the...

Hi @nilodna, perhaps #2184 or #2275 would be good Issues to pick up?
