You can just retrieve them as below, which will get their current value at the time of the save. 

const val = await request.$context.AttributeName;

Alternatively you could use a change request handler, which gives you both the new and old values as properties of the request. See https://customerfx.com/article/responding-to-an-event-when-a-field-is-changed-on-a-creatio-freedom-ui-page/
