-* No module aliasing. (`uos` and `utime` are not available as `os` and `time` respectively.)
-* Modules with a CPython counterpart, such as `time`, are strict [subsets](https://circuitpython.readthedocs.io/en/latest/shared-bindings/time/__init__.html) of their [CPython version](https://docs.python.org/3.4/library/time.html?highlight=time#module-time). Therefore, code from CircuitPython is runnable on CPython but not necessarily the reverse.
+* No module aliasing. (`uos` and `utime` are not available as `os` and `time` respectively.) Instead `os`, `time`, and `random` are CPython compatible.
+* New `storage` module which manages file system mounts. (Functionality from `uos` in MicroPython.)

     * Auto-reload after file write over mass storage. (Disable with `samd.disable_autoreload()`)
