* A lot of minor bugfixes and improvements

### V0.07.05

* Added support for fermentation profiles based on hours in stead of days (defined in settings)
* Added autoresume in case of powerloss / unscheduled reset. If a system is powered off or resets in a quick profile or manual control it will automatically resume the process. Saving happens every 12 hours (1 hour if time unit = hours).
* Added possibility for manual density entries without density sensor
* Improved density sensor calibration / set OG UI and logic
* Quick Profile UI improvements
* Major WiFi connection process improvements
* Minor bug fixes and improvements

### V0.07.01

* Improved memory handling and timing to improve stability
* Density sensor features improved
* Minor backend fixes and improvements

### V0.06.00

* Major system stability and error handling update
* Improved firmware updating procedures
* Added CRC verification for CAN device firmware
* Added display backlight fading

* Backend framework updates

### V0.05.06

* Language support (Norwegian) - More coming soon
* Major performance/response enhancements
* Custom mapping of relay outputs with relay testing function. 
* Pressure sensor can now be calibrated
* Improved pressure regulation algorithm
* Added threshold for pressure regulation
* Added override features in pause menu
* Added "skip to next step" in quick profile mode
* Cleaned up settings, reduced to 8 pages
* Added support for heating control on relay 1-3 when ext. relay is disabled. Note that this will not have current measurement for future safety features
* Improved density sensor integration. Mandatory "set OG" for each session
* Calibration of density sensor can be done at the same time as session/batch OG is set
* Updated UI library framework
* Minor Bug fixes and enhancements

### V0.04.0

* Major update to pressure regulation. Now auto in/out with option to disable gas in in manual / per step in 'fermentation profile'. Automatic gas input now set per step in quick profile.
* Major WiFi/MQTT rewrite. WPA3 disabled due to stability issues with poor WiFi networks.
* Added manual density readings to cloud
* Added another decimal in pressure readings (except kPa)
* New boot sound
* Minor bugfixes

### V0.03.03

* Fixed memory bug that could cause the system to reset
* Added density sensor support
* Added support for temperature from density sensor
* Updated default pressure target to 1.0 bar (until auto-resume / values are stored)
* Added CAN port reset at display module boot to securely connect CAN devices.

### V0.03.01

* Fixed UI memory allocation issue that could make the system crash

### V0.03.00

* Improved temperature regulation
  * User adjustable cooling threshold
  * User adjustable heating threshold
  * More advanced control algorithms
* Automatic pressure regulation
* Improved filters on temperature, pressure and DC power
* Added screensaver: backlight dims to 25% based on user set delay
