Release notes for 5.5.69?

The latest release has broken the dynamic behaviour of one of my column lookups in form builder and to help me debug and see if I can find a workaround I wonder if there are release notes for this release or perhaps a hint of what has changed.

This app is very simple in having one date column and an an id column. The id column has a lookup that checks valid options based on the date (this is logging class instances so it is looking up classes on another table to only provide the options for those that run on the day of the week corresponding to the date). So there is a where clause that calls a stored function to check validity. This worked until yesterday but is no longer working.

This looks like a regression on a fix that Peter made following this post from me a few months ago – https://wordpress.org/support/topic/wp-data-access-trouble-with-getting-dynamic-conditions-to-work-on-a-lookup/

Any insight would be appreciated.
