Activity is still low, but that is typical for the early stages of update testing, particularly minor ones that may not require widespread internal or external testing. As a minor update, iOS 7.1.2 is likely to focus on bug fixes and other tweaks rather than major feature additions, and it likely will not even be put through a developer testing period before release.
Apple has already announced that at least two issues will be resolved in a future software update. The first is a problem which Andreas Kurtz, a security researcher, discovered. Contrary to Apple's claims email attachments are not being encrypted in iOS 7. The second is an issue that results in messages sent to a number no longer using iOS to be sent as an undeliverable iMessage instead of as a SMS.
