" Hello everyone, This link will let you download firmware 1916. There are release notes below.
Firmware 1916 iso, for updating from a CD

Files needed to update from USB

This link has an updated document for how to update from USB -- we had to make a couple of changes to that process to make it work with the new firmware. If you're updating from CD, just follow the same procedure as last time.

New USB process (PDF)

The new firmware is not on the SSD downloads page yet, and it may be a while before it is. Apparently there is a large number of corporate procedures that need to happen before we can officially publish new firmware versions... who knew? However, since the firmware itself actually is ready (the lab has completed successful final testing), we decided to post it in the forum right away, because we know how important this is to everyone here, and we appreciate how understanding you have been about how long the testing process has taken.

Enjoy!

EDIT: To make it easier for us to monitor things, I have created a feedback thread for the update, so we can keep all reports and questions in one place. So if you do run into issues, please report them here. Thanks!

EDIT 2: Yes, the links changed. After further review, it was decided to offer only the firmware with active Garbage Collection for now. The links may need to change again, since we are still working towards the official release of the firmware. If they do, I will update this post again.

BTW: The USB (flash drive update) ZIF file unpacked shows an existing "Updater.bat" file - that's a mistake IMHO since from the info in the USB PDF guide SSDCheck is run first to ID the model (capacity I assume) before running Updater.bat. (And my check of the bat file before/after a 256GB update shows the same 80102.exe call in the Updater.bat file.) I didn't check the ISO but I wish they'd included info on which EXE file is for each specific SSD size (64, 128, 256GB). If anyone knows this info let me know.
I flashed my (1819) firmware 256GB SSD w/1916 and initially (with ext HD dock) saw some Some odd issues after the 1916 Firmware Update.
I also welcome any other Mac (MacBook/Pro or Mac Pro, etc.) M225 owner feedback on 1916 as well. (Curious if any Mac Pro owners were able to use the ISO (CD) updater OK.) Longer term use of course will be a better gauge of 1916 firmware, but I still welcome any reader comments on what they've seen so far.
A later post has their 1819 release notes:
