Unneeded serialization and base64 encoding

Hi,
in your code I’ve seen these lines before and after transient set/get:

Before setting :
$instagram = base64_encode( serialize( $instagram ) );

After getting:
$instagram = unserialize( base64_decode( $instagram ) );

Now, according to set_transient documentation, serialization is not needed before insertion, thus even the base64 encoding it’s not needed.

Thank you
