Rockylinux 9.0 is a rolling update mirror version?

Every time a bug or other problem is fixed, will the image be repackaged and released again?
Recently it has been found that ISO is frequently updated。
Example:
Rocky-9.0-20220728.0-x86_64-dvd.iso
Rocky-9.0-20220807.0-x86_64-dvd.iso

ISO’s are only issued to resolve problems not found on initial release or not found by the testing team. Please see the following bug reports for examples.
