This mu-plugin is for site administrators who want to maintain a clean and predictable URL structure. It stops the platform from automatically saving and redirecting old post slugs after a permalink is changed, which can prevent clutter in the database and unintended redirect chains.

Prevents Slug Storage: The core function is to stop the system from saving a history of old post slugs in the database when a post's permalink is updated.

Eliminates Automatic Redirects: By not storing the old slug, the platform will not create an automatic redirect from the old URL to the new one, avoiding potential redirect loops or conflicts.

Simplifies URL Management: This gives administrators full control over redirects, which can then be managed deliberately through dedicated plugins or server rules for a more organized site structure.

Must-Use Plugin: It is designed as a mu-plugin, meaning it is automatically enabled for all sites on an installation and cannot be deactivated from the standard admin panel, ensuring consistent behavior.

Lightweight Solution: The plugin performs a single, specific function without adding a configuration interface, keeping it simple and focused on its core task.
