WordPress Alpha Version Automatically Installed When I am Not Opted In

[guyhaines]

I just got notifications from two sites (so far) which "updated automatically to WordPress 5.5.3-alpha-49449" .. I went in and re-installed 5.2, but I do not have any directive to install automatically any development release.

Many of my functions files across many sites have

add_filter( 'allow_minor_auto_core_updates', '__return_true' );

Which has opted me into minor releases, but not development releases... for several years.

I just added

add_filter( 'allow_dev_auto_core_updates', '__return_false' );

Which I hope protects me from development releases here on out on those sites. But I worry I will have to spend my day tracking down all sites to manually re-install 5.5.2

@guyhaines this should be resolved now, see more details in #51679.
