WordPress bungles critical security 5.5.2 fix and saves face next day with 5.5.3 update.

The day after WordPress pushed out a critical 5.5.2 security update, [patching a remote code execution bug and nine additional flaws], it was forced push out a second update and then a third 5.5.3 update.
The hiccup is tied to the WordPress auto-update feature that accidentally started sending 455 million websites a WordPress update (5.5.2) that caused new WordPress installs to fail. After realizing the error, it put the brakes on the rollout, and inadvertently triggered an Alpha version of WordPress to be downloaded to some customers.
The issue was corrected quickly on Oct. 30, but not before WordPress site operators reported new WordPress installs failing and others grousing over broken administration login pages. WordPress said a final 5.5.3 update is [now available]
