+
+###### New features:
+
+- Added `--file` CLI flag to run a migration from an explicit `export.json` path while keeping `--path` as the base folder for runtime resources.
+- Added diagnostic lines that show the resolved `export.json` path and a dedicated note when this path differs from `--path`.
+- Added anonymisation support for explicit `export.json` path values in diagnostic logs when `--anonymise` is enabled.
+
+###### Improvements:
+
+- Improved stack trace anonymisation to mask only the absolute machine-specific prefix while keeping plugin-root relative file paths visible.
+
+###### Fixes:
+
+- Updated non-zero exit guidance text to use consistent team wording in the final diagnostic instruction line.
