MacOS 10.14.5 beta 5 and iOS 12.3 beta 5 were released to developers today and within hours to beta testers. These beta releases came only a week after beta 4 which is generally a sign that unless something unexpected turns up the general release should be within days. Nothing particularly exciting in these updates, some new emojis, some bug fixes, an Apple News+ tweak, and in iOS a new TV app. At this point the major development effort is already going to MacOS 10.15 and iOS 13. I only encountered one significant glitch in MacOS 10.14.5 beta 3, which disabled Malwarebytes Premium auto checking, but that was resolved in beta 4 (at least Malwarebytes started working again concurrent with installing beta 4, but that could have been a coincidence).
CONCLUSION: I have found nothing to be wary about in 10.14.5 or iOS 12.3.
