This release contains a fix for LP bug 1484281, "authority data may be deleted during propagation with current values of authority.control_set_authority_field."

For more details see: https://bugs.launchpad.net/evergreen/+bug/1484281

The related upgrade script from this release removes subfield $e in authority tags 100 and 110, but only from the Evergreen default "LoC" authority control set configuration. If your Evergreen system is set up with additional authority control sets besides the default "LoC" one, you will need to run the following pieces of SQL code.

First verify that you have an additional control set besides the default of "LoC". Run the following SQL code and write down the ID number for your additional control set. The number will be an integer like 101.

select *
from authority.control_set
where name != 'LoC'
order by id

In the following code you will need to change the two sections of "control_set = XYZ". Change the part labeled with the text "XYZ", with the ID number from the above query.

If the above query displayed more than one additional authority control set, then you will need to run the code below once for each additional control set ID number.

UPDATE authority.control_set_authority_field
SET sf_list = REGEXP_REPLACE( sf_list, 'e', '', 'i')
WHERE tag = '100' AND control_set = XYZ AND  sf_list ILIKE '%e%';

UPDATE authority.control_set_authority_field
SET sf_list = REGEXP_REPLACE( sf_list, 'e', '', 'i')
WHERE tag = '110' AND control_set = XYZ AND  sf_list ILIKE '%e%';
