# Changelog
**Note:** Unreleased changes are checked in but not part of an official release (available through the Arduino IDE or PlatfomIO) yet. This allows you to test WiP features and give feedback to them.
## Unreleased
- nothing, so far
## [2.3.1] - 2024-01-02
- bugfix for RP2040, as pointed out by [kilrah](https://github.com/kilrah) in issue [#60](https://github.com/LennartHennigs/Button2/issues/60)
## [2.3.0] - 2024-01-02
- renamed Button2 constants, they now start with `BTN_` (BREAKING CHANGE)
- added `Hardware.h` it implements hardware pin abstraction. Needed for unit testing
- added Unit Tests
- added `resetPressedState()` function
- added `ESP32S2S3CapacitiveTouch.ino` suggested by [ryancasler](https://github.com/ryancasler) in PR #57
## [2.2.4] - 2023-06-22
- `getNumberOfClicks()` now works inside a callback and after the `wait()`statement(s).
- Refactored code in `Button2.cpp`
## [2.2.3] - 2023-06-21
- Included PR for issue [#54](https://github.com/LennartHennigs/Button2/issues/54)
## [2.2.2] - 2022-12-16
- Another stab at the bug [#46](https://github.com/LennartHennigs/Button2/issues/46)
## [2.2.1] - 2022-12-16
- Fixed bug [#46](https://github.com/LennartHennigs/Button2/issues/46) that in some instances long clicks are wrongly triggered
## [2.2.0] - 2022-12-13
- Refactored the main `loop()`
- Rewrote click detection
- Cleaned up the long press handling
- Removed compiler switches they made the code unreadable and they only saved a few bytes (could be a BREAKING CHANGE)
- Added `byte getLongClickCount()` function
- Updated the [LongpressHandler](https://github.com/LennartHennigs/Button2/blob/master/examples/LongpressHandler/LongpressHandler.ino) example
- Defaults (x>3)-clicks to triple
- Fixed bug with button ID
## [2.1.0] - 2022-11-03
- Removed the capacitive touch functionality out of main library. (BREAKING CHANGE). The constructor and `begin()` lost a parameter. Instead I provide a custom handler example for cap. touch [ESP32CapacitiveTouch.ino](https://github.com/LennartHennigs/Button2/blob/master/examples/ESP32CapacitiveTouch/ESP32CapacitiveTouch.ino). For reasons, see [#45](https://github.com/LennartHennigs/Button2/issues/45).
- Added an ESP32 timer interrupt example [ESP32TimerInterrupt.ino](https://github.com/LennartHennigs/Button2/blob/master/examples/ESP32TimerInterrupt/ESP32TimerInterrupt.ino) based on [#43](https://github.com/LennartHennigs/Button2/issues/43).
- Added compiler switches in `Button.h` to remove click detection code, as mentioned in [#44](https://github.com/LennartHennigs/Button2/issues/44).
- Clarified the difference between the `setLongClickHandler` and the `setLongClickDetectedHandler` in the README and the [MultiHandler](https://github.com/LennartHennigs/Button2/blob/master/examples/MultiHandler/MultiHandler.ino) example as mentioned in [#41](https://github.com/LennartHennigs/Button2/issues/41). (The handler set via `setLongClickHandler` waits until you release the button, the second one is called as soon as the defined long-click time has passed.)
- Made `byte _getState()` into a `const` function.
## [2.0.3] - 2022-05-26
- Fixed bug with the button ID as pointed out by [Jon](https://github.com/mscreations) in [#39](https://github.com/LennartHennigs/Button2/pull/39).
## [2.0.2] - 2022-05-21
- Added example for the [M5Stack Core2](https://github.com/LennartHennigs/Button2/blob/master/examples/M5StackCore2CustomHandler/M5StackCore2CustomHandler.ino) - showing how to add a custom handler for the touch buttons.
## [2.0.1] - 2022-04-22
- Fixed bug `longclick_detected_counter` is not properly initalized as mentioned in [#37](https://github.com/LennartHennigs/Button2/pull/37).
## [2.0.0] - 2022-04-04
- House keeping
- Refactored `loop()` - cleaned up conditions, should be easier to understand now.
- Renamed `getAttachedPin()`to `getPin()` (BREAKING CHANGE).
- Fixed a bug that the first click type was falsly returned by `getClickType()`.
- Possibility define your own "_getState" function for non standard buttons as suggested in [#32](https://github.com/LennartHennigs/Button2/issues/32).
- Refactored `isPressedRaw()` to also use `_getState()`.
- Introduced a `VIRTUAL_PIN` constant using it in the constructor or `begin()` will skip pin initalization.
- Added `setButtonStateFunction(StateCallbackFunction f)` to assign your own "_getState" function.
- Added [CustomButtonStateHandler.ino](https://github.com/LennartHennigs/Button2/blob/master/examples/CustomButtonStateHandler/CustomButtonStateHandler.ino) example.
- Improved click type handling.
- Added `clickType` and removed constants for determining the click type (BREAKING CHANGE)
- Renamed `getClickType()` to `getType()` (BREAKING CHANGE)
- Added `clickToString` function to print the `clickType` enum value
- Added IDs button instances
- Added `getID()`, it returns an auto incremented `int` ID for the button, as suggest in [#34](https://github.com/LennartHennigs/Button2/pull/34)
- Added `setID()`, it allows you to set your own IDs but then you need to ensure its uniqeness yourself
- Added possibility to use the button class inside your main `loop()` function (instead of using callback handlers)
- Added `bool wasPressed()` function
- Added `read(bool keepState = false)`, it returns the button press type (as a `clickType` enum)
- Added `wait(bool keepState = false)`, it combines `wasPressed()` and `read()` methods and halts execution until a button press took place
- Added `waitForClick()`, `waitForDouble()`, `waitForTriple()` and `waitForLong()` as well
- Added [ButtonLoop.ino](https://github.com/LennartHennigs/Button2/blob/master/examples/ButtonLoop/ButtonLoop.ino) example to showcase the "loop" functions
## [1.6.5] - 2021-09-12

## [1.6.4] - 2021-09-12

## [1.6.3] - 2021-09-12

- added examples to the [README.md](https://github.com/LennartHennigs/Button2/blob/master/README.md)
- initialized `pin` in `_getState()`
- a bit of variable clean up
- updated setting of inital state of `state` and `prev_state`
## [1.6.2] - 2021-06-22
- initialized `pin` property to 255 instead of -1, as pointed out by [rin67630](https://github.com/rin67630) in issue [#26](https://github.com/LennartHennigs/Button2/issues/26)
