# Changelog for Abit



## v0.4.0

  * Feature - Implemented fast atomics resetting via `Abit.clear/1` and `Abit.Counter.clear/1`.

  * Feature - Implemented bit toggling via `Abit.toggle_bit_at/2` and `Abit.Bitmask.toggle_bit_at/2`.

  * Feature - Implemented set theory missing operations: `Abit.difference/2`, `Abit.symmetric_difference/2`, and `Abit.invert/1`.

  * Deprecation - `Abit.merge/2` is deprecated in favor of `Abit.union/2` to align with standard set theory terminology.



## v0.3.3

  * Feauter - `Abit.Atomics` implements `serialize/1` and `deserialize/1` functions.



## v0.3.2

  * Fix - compile warning about using `^^^/2` in `Abit.Counter`



## v0.3.1

  * Fix - work with elixir 1.7 by not using Kernel.floor/1 & Kernel.ceil/1



## v0.3.0

  * BREAKING - removed `Abit.Matrix` module. Extracted to [matrax](https://hex.pm/packages/matrax).



## v0.2.4

  * Feature - `Abit.Counter` implements `Enumerable` protocol



## v0.2.3

  * Feature - `Abit.Matrix` implements `add/3`, `exchange/3`, `compare_exchange/4`, `min/1`, `max/1`, ... functions.

  * Feature - `Abit.Matrix` implements the `Enumerable` protocol

  * Feature - `Abit.Bitmask` implements `to_list/2`function.

  * Feature - `Abit` implements `to_list/1` function.



## v0.2.2

  * Feature - `Abit.Matrix` module for working with atomics as an M x N matrix.



## v0.2.1

  * Performance - improvements for the `Abit` & `Abit.Bitmask` module functions



## v0.2.0



### Abit

  * BREAKING - renamed function `set_bit/3` to `set_bit_at/3` to make it consistent with the API of the Bitmask module.



### Abit.Counter

  * BREAKING - Added an option `wrap_around` to set wrap around behavior. By default wrap around is disabled from now on.

  * BREAKING - Using built-in signed/unsigned implementation of integer matching instead of the custom one. Signed integers now wrap around the same way as in Elixir.

  * BREAKING - The return value of `put/3` and `add/3` changed to `{:ok, {index, final_value}}` or `{:error, :value_out_of_bounds}` if the option `wrap_around` is set to false and value is out of bounds.
