a7iv Firmware version 1.05 and 1.10 updates

Got an email from Sony Australia advising the a7iv has a firmware updates from v1.01 to v1.05, and then to v1.10.

Here's what it brings:
Alpha 7 IV firmware update now available.
Discover intuitive operation that goes further with new features, giving you even more creative freedom.

New features include:
Select M and S sizes in addition to L when using the RAW recording lossless compression method
Retain shutter speed and ISO sensitivity settings dedicated for flash photography
Touch Shutter function now added
Improved accuracy of Eye AF feature
Record camera’s serial number in the metadata of movie files
Improved operability of Wi-Fi connections
One minute setting to Power Save by Monitor menu now added
Brightness of viewfinder display more responsive to ambient brightness
Improved operational stability of the camera

Rather clunky, but it works.
Needs to be done in 2 separate updates: from v1.01 to v1.05, and then from v1.05 to v1.10, downloading each of the updates and uploading them in turn.
You need to down load each program to your computer from the Sony website, then transfer the program icon to your Sony formatted SD memory card, insert that memory card into slot A, go to Menu - Set-up - Set-up Option - Version - read the instructions and hit install. Camera needs to have a fully charged battery, and it takes about 6 minutes.
Having done the v1.01 to v1.05 update, you repeat the process with the v1.05 to v1.10 update.

What are the M and S settings in lossless compressed RAW?

On SAR it is reported the firmware update is pulled? Couldn't find any other reports....

Guess it should be medium or small, as in Sony finally would support smaller RAW files rather than just full sized ones.
Some chatter over at DP Review that it's been pulled due to update issues depending on what you had the RAW compression set at before the update.

Do I understand correctly that α7 IV has returned to the traditional method firmware upgrades that do not require a separate computer software to be run to do the update?

What site? Checked the Dutch Sony site and only the 1.10 is there, not the 1.20 version.

Well, it is better then you get with your A900

So the 1.10 is out there since several days and it seems people are split in terms of their experiences. There are some that are happy, some still not, some experience worse af after upgrade.
Definitely doesn't help me to decide if I should buy this one...
