+### Upgrading to Memgraph v2.15.0
+
+<Callout type="info">
+
+Starting from Memgraph version 2.15.0, password hashing
+has been fortified with salt for improved security. Previously, passwords were
+hashed using SHA256 without salt. Please note that bcrypt, which is the default
+hashing algorithm, has always incorporated salt for enhanced security.
+
+- **Automatic Migration:** Passwords hashed without salt will be automatically
+  reverted to the saltless algorithm upon upgrade. Subsequent successful logins
+  trigger a rehashing process with salt, updating the data on disk.
+- **Seamless Transition:** Most users will experience a seamless transition
+  without any manual intervention. A user's first login post-upgrade triggers
+  the hash update.
+- **Migration Considerations:** Upon starting Memgraph version 2.15.0 for the
+first time, ensure that the `--password-encryption-algorithm` flag is correctly
+set to match the actual hashing algorithm used. This is crucial for maintaining
+authentication data integrity.
