Hi @Lexy
Ah the changelog is on the beta site. Good to know. I also subscribe to the newsletter to not miss out of any changelogs in the future.
So just to be sure we do the correct thing next time:
In IT in general deprecation means that use of a certain functionality or API is discouraged, but you are still permitted to use the functionality. This also means the functionality remains as is, but you are encouraged to use another method. After a deprecation announcement typically another announcement is made that you per a-certain-date should really change your code because in a new release the functionality will be changed or removed.
So when bunq accounces that on October 8-th 2019 the notification_filters will be deprecated should you update before 8-th of October or will there be another announcement that will announce the removal of the deprecated notification_filters?
