Apple issues iOS 9.3.6 and iOS 10.3.4 updates for older iPhone and iPad models
Apple has quietly issued updates to some earlier iOS versions, including new builds of iOS 9.3.6 and 10.3.4 for use by older iPhone and iPad models that are not able to update to the latest iOS versions.

Issued alongside the update to iOS 12.4 that is available for many iOS devices, Apple has shipped an update that applies to devices not able to use the current operating system release. On Monday, updates for iOS 9.3.6 and 10.3.4 were made available to download to a small number of devices.
The iOS 9.3.6 update is meant for the iPad 2, iPad mini, iPad 3, and iPhone 4s, while iOS 10.3.4 is for the iPad 4 and iPhone 5.
According to release notes for the updates, they consist of a number of security updates, as well as a fix for a GPS bug.
Apple's main focus is on keeping its main operating system releases up to date and secure, but the company can periodically issue software updates for older operating systems. Typically this is used to close security issues that affect the older hardware.
The updates will be the first of their kind for the older iOS hardware for quite some time.
Apple issued iOS 9.3.5 in August 2016 and iOS 10.3.3 in July 2017. Code signing for each version was stopped in October 2016 and October 2017 respectively.

Comments
In Canada, the release notes talk about new data transfer option.
I have no fu**ing idea why Apple doesn't promote this use more often. Apple would easily take over Alexa if they allowed a docking mode for older devices people have laying around.
I still can’t load all my iCloud books on iBooks.
These updates do not include any security fixes, only a GPS bug fix. Only iPhones and cellular iPad models have GPS hardware.
Oddly the iPhone 5C misses out even though the iPhone 5 is getting an update. Perhaps the GPS hardware/firmware in the iPhone 5C is different because the model is a year newer, and doesn’t have the bug?
Apple recommends all users with eligible devices install the new updates. Apple devices won't be affected until November 3, 2019, so there should be plenty of time for users with affected iPhones and iPads to install the new software.
According to Apple, those who don't update to the new version of iOS by November 3 might see their iPhones and iPads failing to maintain an accurate GPS position, and features that rely on correct date and time, like syncing with iCloud and fetching email, might not work.”

Its endlessly waits for Download and Install on iPhone 4s.
After installation, the iPad 2 says Hello, and wait for activation indefinitely, rendered it totally unusable!
The iPad mini can’t even find the update!
After reinstalling 9.3.5 ITunes says the system is up to date when asking to check for update.
