(Original title: "Regression: Smart group with Change log criteria is not saved.")

If you create a smart group which uses a relative date filter (e.g. "Last 60 days" or "This calendar current year"), the relative date filter is not saved correctly.

This issue entails two aspects:

1. (Code update in 5.16.4) Fix the code so that smart groups are properly saved
2. (Data cleanup; case-by-case) Identify any smart-groups which were created or edited in the past month (5.16.x). Determine if they should be updated to use a relative date filter.

The following fields are believed to affected:

• log_date_relative
• pledge_payment_date_relative
• pledge_start_date_relative
• pledge_end_date_relative
• pledge_create_date_relative
• member_join_date_relative
• member_start_date_relative
• member_end_date_relative
• birth_date_relative
• deceased_date_relative
• mailing_date_relative
• relation_date_relative

• relation_end_date_relative
• relation_action_date_relative
• contribution_recur_start_date_relative

• contribution_recur_cancel_date_relative
• contribution_recur_end_date_relative
