For those who do not know what these update packages are, we can make a brief summary of it. These types of versions go beyond the direct updates in the System Preferences and in the case of Combo updates, what Apple offers is to offer an update option from the initial version of the software on our Mac. With it we could update in one jump from any version to the latest available such as macOS Catalina 10.15 to the latest available macOS Catalina 10.15.7.
In the case of Delta versions, Apple offers a follow-up upgrade option. In this way users can update their equipment for example, from a Big Sur 11 to Big Sur 11.1 version. This now appears not to be available as a standalone package in the latest version of Apple's operating system.
Every time Apple releases an operating system update, these update options are published practically in unison, but in this case according to the Eclectic Light Company report, published later in iPhoneHacks, Apple has stopped providing separate delta and combo update packages.
Manual downloadable delta and combo updates for Big Sur are no longer available. I will let our resident #MacAdmins expert explain 👇

Most of the users use the traditional update system but some used this type of independent files in the form of .dmg files to perform the updates manually, these packages are generally smaller than the full update and They are useful if the user has a problem installing it from the System Preferences. Well now it seems that these are no longer available in the new versions of macOS Big Sur.
It seems Apple is asking at a forced marches that we abandon its platform and go to windows!
