It's already time for 0.28 thanks to our super short release cycles. Now, it' official...we hit 4000 stars on Github. That's amazing. Sorry, not as amazing as all the stuff that was going on for 0.27 but still pretty awesome.

### Reload automation rules

This release brings you a huge improvement of the [automation] and [group] handling. Both can be reloaded without a Home Assistant restart by calling their new reload services. The automations can be controlled directly from the frontend.

### Raspberry Pi installation guide
Singleboard computers are very popular to run Home Assistant. To support this fact, the [installation documentation][rpi] for the Raspberry Pi devices was re-written to get users started as quickly as possible. [@Landrash] took the lead with on this tasks with help from [@kellerza] and [@MartinHjelmare]. 

### Climate and  cover
There are countless bugfixes included in this release which will make your experience with the `climate` and the `cover` platforms better. Two week ago was the biggest merger of implementations released that ever happened in the history of Home Assistant. Thanks to [@turbokongen], [@pvizeli], [@djbanks], [@danielperna84], and others the improvements on the code and the frontend side is continuing... 

### API documentation
The [Home Assistant API Documentation](https://dev-docs.home-assistant.io/en/dev/) is a great addition to the already existing user documentation. The focus is not end-users but developers who want to get details about the code without actually browsing the code on Github.

### Configuration validation
The validation of the configuration is still on-going. Approximately 80 % is done. This means that we will propably talk about this topic in the next release notes again. To align the configuration of components and platforms we needed to break some. Please refer to the Breaking changes section to check if you need to update your configuration or simple check your log for configuration validation errors. Thanks to [@kellerza], [@fabaff], [@Teagan42], and [@pvizeli] for your effort!

### Breaking changes

- [OpenweatherMap] entity IDs are now like `sensor.owm_temperature`. Previously they were like `sensor.weather_temperature`. Apologies for this change, but we needed to make OpenWeatherMap more generic now that we have many weather platforms.
- Updates of configuration variables due to configuration check or alignment with other platforms. Please update your configuration entries according to the documentation:
  - [OctoPrint] component
  - mFi platform ([switch][mfi-switch] and [sensor][mfi-sensor])
  - NX584 Alarm Control Panel
  - Mediaplayer platforms [FireTV], [Kodi] and [MPD]
  - [switch][command-line-switch] and the [cover][command-line-cover] `command_line` platforms
- Custom components extending `BaseNotificationService` need to be aware that `kwargs.get(ATTR_TITLE)` will now return `None` if a title has not been set, and will need to specify `kwargs.get(ATTR_TITLE, ATTR_TITLE_DEFAULT)` if they always require a title.
