v1.2.0

• Updated Rust edition from 2021 to 2024
• Updated MSRV from 0.82 to 0.87
• Removed polyfill code for features that have been stabilized in Rust 0.87

v1.1.0

New features

• Added nth_front() and nth_back().

v1.0.0

New features

• When the buffer is full, push_front() and push_back() now return the replaced element (contributed by Zacchary Dempsey-Plante).

Other changes

• Increased the minimum supported rustc version to 1.82

v0.1.9

• This release does not introduce any new features or bug fixes. It only changes the dev-dependencies used by unit tests (contributed by Ben Beasley).

v0.1.8

New features

• Added optional support for embedded-io and embedded-io-async (contribyted by DaneSlattery).

Other changes

• Renamed the use_std cargo feature to std (the old use_std is now an alias for std, so this is not a breaking change).

v0.1.7

New features

• Implemented the traits Index<usize> and IndexMut<usize> for CircularBuffer. Now elements of the buffer can be accessed and modified with indexing operations (buf[index]), like in the following example:

  use circular_buffer::CircularBuffer;
  let mut buf = CircularBuffer::<5, char>::from(['a', 'b', 'c']);
  assert_eq!(buf[0], 'a');
  buf[1] = 'd';
  assert_eq!(buf[1], 'd');

• Added new methods to fill the whole buffer, or the spare capacity of the buffer: fill(), fill_with(), fill_spare(), fill_spare_with().

• Added a new alloc feature that brings heap-allocation features to no_std environments through the alloc crate (contributed by Haoud).

• Implemented the BufRead trait for CircularBuffer (not available in no_std environments).

Bug fixes

• Fixed an out-of-bounds read in remove().
• Removed #[must_use] from drain(): it is perfectly acceptable to ignore the return value from this method.

Other changes

• Raised the minimum rustc version to 1.65

v0.1.5

• Added try_push_back() and try_push_front() as non-overwriting alternatives to push_back() and push_front() (contributed by Rinat Shigapov in GH-5).
• Added drain() to remove ranges of elements.
• Added make_contiguous() to return a contiguous mutable slice of elements.
• Iter and IterMut now implement the Default trait.
