## [0.1.2] - 2021-10-17

### Added
A Raspberry Pi example

### Fixed
- Error in the month/weekday setting

## [0.1.1] - 2021-07-21

### YANKED FROM CRATES.IO!

### Fixed
- Make sure that non relevant bits in the time and date register are ignored before the decoding, following this hint in the datasheet: *Bit positions labelled as x are not relevant. Bit positions labelled with N should always be written with logic 0; if read they could be either logic 0 or logic 1* - fix by [pyaillet](https://github.com/pyaillet)
- Error in the month/weekday setting

## [0.1.0] - 2021-04-05

### Changed
- All the alarm setting functions keep the current setting of the AE bit, enabled or disabled
- GitHub repository visibility changed to "public"

## [0.0.4] - 2021-04-04

### Added
- Get and clear Voltage Low detector flag
- Get external clock mode flag status
- Get main clock status (running/stopped)
- Get power-on-reset-override flag status
- `rtc_init` function (clears various control bits, sets timer frequency to power saving mode)
- `disable_all_alarms` wrapped to shut off all alarms at once
- Get timer flag status
- Get timer interrupt status
- Get alarm flag status
- Get alarm interrupt status
- Read the alarm minutes, hours, day and weekday 
- Read the current timer value
- Read century value (0 or 1)
- Set century (0 or 1)
- Get clock output status (enabled/disabled)

### Changed
- Control enum fields changed to On/Off

- Century is set to zero when month is set
  

## [0.0.3] - 2021-04-03

### Added
- Function for setting time only, with the date left unchanged

## [0.0.2] - 2021-04-03

### Added

### Removed
- All the enable_ and disable_ functions, replaced by control_ functions

## [0.0.1] - 2021-04-02

### Added
- Setting and reading datetime
- Enabling/disabling alarms and alarm interrupt
