 ### Internal aspects to consider
 
 - Frequently, at the same time that you want to do an update of parameters or listing, you also want to do something extra before or after.
   The `Base Aave v3 Payload` defines `_preExecute()` and `_postExecute()` hook functions, that you can redefine on your payload and will the execute before and after all configs changes/listings you define.
 
 - The payload also allow you to group changes of parameters and listings, just by defining at the same time the aforementioned `newListings()`, `capsUpdate()` and/or `collateralsUpdates()` and so on. For reference, the execution ordering is the following:
   1. `_preExecute()`
-  2. `eModeCategoriesUpdates()`
-  3. `newListings()`
-  4. `newListingsCustom()`
-  5. `borrowsUpdates()`
-  6. `collateralsUpdates()`
-  7. `rateStrategiesUpdates()`
-  8. `priceFeedsUpdates()`
-  9. `assetsEModeUpdates()`
-  10. `capsUpdates()`
-  11. `_postExecute()`
