 * Fixed network values computation: replaced the simple arithmetic with `saturating_sub` and `saturating_add`.
 * Converted values read in `/proc/meminfo` from KiB to KB (because contrary to what is said in the manual, they are in KiB, not in KB).
 * macOS: Rewrote `get_disks` function to remove the Objective-C dependency.
 * Added `SystemExt::get_long_os_version`.
 * Linux: Fixed sequences for disks.
 * Linux: Allowed `/run/media` as a mount path.
 * Windows: Fixed disk size computation.
 * Linux: Fixed virtual memory size computation.

# 0.16.1

 * Added flag to remove APIs prohibited in Apple store.

# 0.16.0

 * Windows: show removable drives on Windows.
 * Switched to Rust 2018 edition.
 * Split `SystemExt::get_version` into `SystemExt::get_kernel_version` and `SystemExt::get_os_version`.
 * Windows: added support for `get_kernel_version` and `get_os_version`.
 * Changed return type of `SystemExt::get_physical_core_count` from `usize` to `Option<usize>`.
 * Added `SystemExt::get_physical_core_numbers`.

# 0.15.9

 * iOS: Fixed build.
 * Fixed cross-compilation.

# 0.15.8

# 0.14.9

 * Linux: fixed CPU usage computation.
 * Windows: fixed load average constants.

# 0.14.8

 * Linux: fixed network information retrieval by replacing `usize` with `u64` because it was too small on 32 bits systems.
 * Linux: get each core frequency.

# 0.14.7

 * Raspberry Pi: fixed temperature retrieval.

# 0.14.6

 * Linux: fixed infinite recursion when getting disk.

# 0.14.5
