+ALL FEATURES ENABLED (Python 2 & 3):
+
+- HTTP / HTTPS
+- FTP / FTPS
+- SFTP
+- TCP / UDP
+- Reliable UDP (seq/ack)
+- Resume transfers
+- Directory sync (compare size + SHA-256)
+- AES encryption (passphrase or ECDH key exchange)
+- Compression (gzip)
+- Multicast UDP
+- Rate limiting
+- Size limits
+- Auth + path enforcement
+
+PUBLIC API (UNCHANGED):
+    download_file_from_internet_file(url)
+    download_file_from_internet_string(url)
+    upload_file_to_internet_file(fileobj, url)
+    upload_file_to_internet_string(data, url)
+
+Directory sync policy:
+    Existing files are compared by size + SHA-256; only changed files are transferred.
