+### Fixed
+- A full restore onto MySQL/MariaDB stopped with "Incorrect string value" when it created a table
+  (of an app that is not installed here) whose rows hold emoji or other 4-byte characters: the
+  table got 3-byte utf8. Tables the restore creates now get this installation's character set and
+  collation (utf8mb4). Found in a disaster recovery simulation onto MariaDB.
+
+### Changed
+- README: a roadmap, the tested disaster recoveries, measurements for OVH S3, the Storage Box over
+  SFTP and SMB, how to build the SMB extension when PECL is down, and what works without shell
+  access. The guide lists shell access among what you need.
+- The full-restore integration test checks a 4-byte character in a table the restore creates, and
+  retries app installs from the app store.
