v0.4.0

[v0.4.0] - 2023-02-07

This release fixes an overflow of the lookahead buffer. Users are advised to
upgrade from previous releases to avoid filesystem corruption.

Added

• Added Path::from_str_with_nul and path! to create Path instances from
  str.
• Added Eq and PartialEq implementations for Path.

Changed

• Made Path::from_bytes_with_nul_unchecked const.
• [breaking] Replaced LOOKAHEADWORDS_SIZE (measured in multiples of four
  bytes) with LOOKAHEAD_SIZE (measured in multiples of eight bytes) in
  driver::Storage so that all possible values are valid. (See the lookahead
  size fix below for context.)
• [breaking] Require &mut self in driver::Storage::read for compatibility
  with embedded_storage.

Fixed

• Fixed the lookahead size reported to littlefs2-sys. Previously, the
  reported size was too large by the factor of 8, potentially leading to a
  buffer overflow causing filesystem corruption. Fixing this means that
  Storage::LOOKAHEADWORD_SIZE values that are not a multiple of 2 can now
  lead to an error. Fixes #16.
• Propagate errors in littlefs callbacks instead of panicking.
