Please tell me the reason for this change. Due to this change, many blogs no longer display their posts.

In Japan, “/%year%/%monthnum%%day%/%hour%%minute%%second%/” permalink is used in a famous blogging platform. Many blogs that have migrated from the service to WordPress with the same permalink are in trouble.

It was better not to do it with a minor update. I think we should make an announcement in advance and do it with a major update.
