Here is the response I got from Motorola. The link mentioned in the message (all the links except for the blog all go to the same page) is not helpful. I love that the G5+ is now called an 'older device', but it's probably based on a misunderstanding. All the countries mentioned in the discontinued chennels list are now covered by the 'reteu' channel. The author is possibly not aware that 'retgb' has remained separate - even, I suspect, in 'newer devices'. Anyway, this reply, while polite, is not very useful as it doesn't recognise the difference between security updates and Android version updates. As Macdtek says above, any security update from this year would be nice.

Dear Mr. Thomas
Thank you for contacting Motorola.
Thank you for your email.
As far as "Software Channel" is concerned. - in older device there were channel that are country specific such as "RetFR", retDE, retPL etc. etc. and the trend over time that they all get under blanket reteu - in some newest devices, there are no more retGB, however some, such as yours still have retGB.
We do not know why this is happening in such order, but it is pretty likely that regb will be phased out in the future.
The relevant team is aware that some countries have not received the updates yet and they are working on releasing such updates.
We try to deliver upgrades as soon as they are ready. Across our product portfolio, the mixture of devices, regions and distribution channels means that we have hundreds of software versions to validate and test before pushing to your specific device.
There can be dependencies on carriers and other key partners that will take more time (certifications, independent testing or requests for additional changes). This is why sometimes you will see an upgrade for a device model go to one group of users, but take significantly longer to get to another - even in the same region.
As soon as we know your specific device will be upgraded and when, we post the latest information on Motorola’s software updates page<https://mobilesupport.lenovo.com/uk/ek/softwareupgrade>.
We also have a blog<https://plus.google.com/u/0/+DavidSchuster/posts/1q74Bx3K4my> that discusses current software update issues and questions hosted by one of our internal experts!
We get their information from the same software updates page<https://mobilesupport.lenovo.com/uk/ek/softwareupgrade>, so if you don’t see a specific date on our site, it’s because we don’t have a date for your device yet.
I recommend to check our Software Update Page occasionally -

For any further assistance or information please do not hesitate to contact us, quoting your Customer Reference number. We are reachable on 03339 997 550 to discuss the matter further with one of our experienced customer service agents. Please contact us any time between the hours of 8 AM and 6 PM from Monday to Friday.
Kind regards,

Why are G5 Plus phones on the 'retgb' software update channel still on the November 2017 security update? Phones in Brazil, India (for sure), the USA and EU (I believe) have additionally had January and March 2018 updates? I know this from the evidence of my own phone and from contributions to Motorola forums on the Motorola and Android Central sites.
Does Motorola think the UK market is so small that it can't be bothered with updates? Or does Motorola think the UK is covered by 'reteu' channel updates? It isn't. For whatever reason (maybe wifi channel ranges, which aren't standardised worldwide) the UK has always had a separate Motorola update channel.
Can you please ask the relevant department to release the January and March updates to the UK?
Best regards,
Graham Thomas
