Last update v2.4.24 breaks around 75 of our websites.

Casually chaging ID’s from panel-grid to panel-row-style? How could you do something like that without giving a setting? We have around 75 websites for clients styled on the ID’s of the panel-grid. Not using Siteorigin CSS but creating our own CSS. What can I do to prevent getting angry clients. Not updating is not an option because of automatic updating. Please help!
