## [0.5.0] - 2023-12-11
= refactor API, begin()
- add **uint8_t getAddress()**
- update readme.md
- update examples
----
## [0.4.7] - 2023-09-24
- add Wire1 support for ESP32
- update readme.md
- minor edits
## [0.4.6] - 2023-05-24
- renaming #defines PCA963X... to prepare merge with PCA9634.
- old defines will work until next major release

#### 0.5.0 Breaking change
Version 0.5.0 introduced a breaking change.
You cannot set the pins in **begin()** any more.
This reduces the dependency of processor dependent Wire implementations.
The user has to call **Wire.begin()** and can optionally set the Wire pins
before calling **begin()**.

See PCA9635.h and datasheet for settings possible.

To configure the library after startup one can set the MODE1 and MODE2 configuration registers.
