+  - Go module path renamed from github.com/seaweedfs/seaweedfs to
+    github.com/hanzoai/s3; the Go sources import the hanzoai path throughout,

+  - Package tree relocated from the upstream weed/ directory to s3/; the CLI
+    entrypoint lives at s3/s3.go.
+  - Command binary renamed from weed to s3 (Makefile BINARY = s3); the CLI
+    banner and subcommand descriptions are branded "Hanzo S3".
+  - gRPC service identifiers renamed to Hanzo-prefixed names (for example
+    HanzoClient, HanzoFilerClient, HanzoIdentityAccessManagementClient) under
+    s3/wire/.
+  - Go toolchain pinned to go 1.26.4 in go.mod.
+  - Version constants set to the 4.34 series in s3/util/version/constants.go.
+  - LICENSE preface augmented with a Hanzo AI, Inc. copyright line while
+    preserving Chris Lu's copyright and the complete Apache-2.0 license text.
+  - The S3-compatible object storage API under s3/s3api/ is retained as the
+    primary product surface.
