Apple today seeded the fourth beta of an upcoming macOS Catalina 10.15.5 update to developers for testing purposes, one week after seeding the third beta and over a month after releasing macOS Catalina 10.15.4 with Screen Time Communication Limits, iCloud Folder Sharing, and real-time Apple Music lyrics.

The new macOS Catalina beta can be downloaded from the Software Update mechanism in System Preferences after installing the proper software from the Developer Center.
macOS Catalina 10.15.5 introduces a new Battery Health Management feature for Mac notebooks, which is designed to extend the overall lifespan of a Mac's battery by reducing the rate of chemical aging.
The Battery Health Management feature analyzes the battery health of a laptop and its charging pattern, and in some cases, will preserve battery longevity and health by not charging a MacBook to its full capacity, which can reduce battery life.
When a Mac is used plugged in and the battery is largely kept full, Battery Health Management will kick in and will stop short of a full charge. The feature can be enabled and disabled in the Energy Saver section of the System Preferences app.

I hope actually that there will be no major release anymore. Why not just announce what is coming in the next two years and roll it out slowly, feature by feature? I think that this is a much better approach to OS development and would give Apple time to make its OS more stable. I don't want a new OS version each year. I don't need a new OS each year, actually I am happy with what we have now.
i am hanging on to this thing while it sits awaiting an operating system. For a little while longer.
But srsly Apple, get it together.
I've disabled auto-update on all my devices ... my next update will be on 10.16.XXXXXX when WWDC releases 10.17 beta
I do not trust apples software QA/QC anymore
