Apple releases macOS High Sierra 10.13 Supplemental Update with bug fixes for Adobe InDesi...
Apple on Thursday issued a supplemental update for its macOS High Sierra operating system, squashing a password hint bug in Disk Utility, a few more minor bugs and improving the update's installer. The changes were so minor, it didn't even warrant a point-zero-one distinction.

The macOS High Sierra 10.13 Supplemental Update is now available as a free download from the Mac App Store. According to Apple, the update improves the stability, reliability and security of a Mac, and is recommended for all High Sierra users.
Specifics for the update include:
macOS 10.13 High Sierra launched to the public last week, with mostly under-the-hood improvements. Most notably it features the new Apple File System for Mac, as well as supports for HEVC video, HEIF image encoding, and Apple's Metal 2 graphics platform.
Apple is working on a macOS 10.13.1 update for High Sierra that remains forthcoming. The first beta of macOS 10.13.1 was issued to developer last week.

To your point, @randominternetperson, Apple has used additional digits when they issued an update to an update. Examples include, but are not limited to:
edit: No idea of the size of these supplemental updates, but my research found that Apple has been doing this as far back as 5 years ago:
I'd say that Supplemental Update was less confusing than #.#.# v#.#.
My laptop was still encrypting the drive (I didn't know it was still doing it) and when the update patch prompted to restart my laptop, I got a bad error saying the patch could not be installed due to the drive still being encrypted, and from that time forward, each restart would only attempt to re-install the patch and not let me back into the system.
So be careful. The Apple Support technician had the nerve to blame me for clicking the restart button instead of waiting to do it later in the day even after I mentioned to him how a user is supposed to know to not install an auto-update patch while the drive is being encrypted! It was my first bad experience with Apple support and Apple in general.
All my data resides in the cloud so 1.25 hours later I was back up and running (without their help) but be forewarned. Avoid any MacOS updates if drive-encryption has not yet completed.
It is not a point release, so one would think that it is compatible with the Nvidia graphics driver - you would be quite wrong. Long story short I had successfully installed High Sierra on a Mac Pro 2010 (2009 firmware update) and had it working with the OS SSD in PCIe slot 2, four SSDs in the original drive bays and a GTX970 (non EFI) graphics card in slot 1 with the original Apple GT120 (EFI) in slot 3 as a backup should an install go wrong...
Plugged monitor into original Apple graphics card just in case, update installed, but on reboot got stuck in reboot loop and would not load the OS. Took out GTX970 card, and put the GT120 (EFI) in slot 1. This is sometimes required to get things working on installation of updates. Machine loaded into OSX, completed installed though with garbled graphics (4K monitor). Managed to change the resolution down 2560x1440 at 30Hz (60Hz will not display properly).
NVidia's driver is not compatible, so Apple's standard OSX driver is in use. Putting the GTX970 back in - with the GTX970 in slot 1, GT120 in slot 3 (monitor attached to GT120) the machine will not successfully boot - Apple logo, then about 75% in it'll restart. Swapping the cards around does not solve the issue. The only way to get the machine to boot into the OS is to completely remove the GTX970 card from the machine.
PRAM resets and what not do not solve this issue. I am wondering if after NVidia update the driver whether or not this issue will even be resolved. It looks like a graphics card problem, but I have never seen this behavior before - usually even if the driver is incompatible, the machine would still boot into the OS successfully.
I hope this helps someone avoid the trouble I have had with this. Surely, this is NOT a point release, it obviously changes too many things. I only installed this because like Karmadave, Mail seems a bit buggy sometimes and I hoped this update would fix it. Big mistake.
As an aside, if you are installing High Sierra on a Mac Pro 2010 you will need to make sure the OS drive is in one of the original hard disk bays otherwise the firmware update required during the install of the OS will fail. I learned this after struggling with this issue due to my OS SSD being mounted on a SATA3 card in a PCIe slot (slot 2, which I recommend after you have successfully got the OS installed). I have not read this advice anywhere on the web, so hope this helps others having trouble installing High Sierra.
Has anyone else experienced this? I tired it several times and I always get the same result.
It's also worth noting that none of the 50+ apps that are deleted go to the Incompatible Software folder.
