+	  * Has an improved auto-exposure algorithm.  To use it, set `CAPTURE_EXTRA_PARAMETERS="-mean-value 0.3 -autoexposure 1"` in config.sh (a ffuture version will allow this to be set via the WebUI).
+	  * Has many new settings including support for most of the text overlay features that are supported by the ZWO version.  The "extra text" feature will be supported in a future version).
+	* New and changed config.sh variables, see the [Software Settings](https://github.com/thomasjacquin/allsky/wiki/allsky-Settings) Wiki page for more information:
+	  * `IMG_UPLOAD_FREQUENCY`: how often the image should be uploaded to a website.  Useful with slow uplinks or metered Internet connections.
+	  * `IMG_CREATE_THUMBNAILS`: specifies whether or not thumbnails should be created for each image.
+	  * `REMOVE_BAD_IMAGES` now defaults to "true" since bad-image detection is now done after a picture is saved rather than once for all pictures at the end of the night.  This helps decrease problems when creating startrails, keograms, and timelapse videos.
+	  * `IMG_PREFIX`: no longer used - the name of the image used by the websites is now whatever you specify in the WebUI (default: image.jpg).
+	  * **NOTE**: When upgrading to 0.8.3 you MUST follow the steps listed [here](https://github.com/thomasjacquin/allsky/wiki/Upgrade-from-0.8.2-or-prior-versions).
+	* Replaced `saveImageDay.sh` and `saveImageNight.sh` with `saveImage.sh` that has improved functionality, including passing the sensor temperature to the dark subtraction commands, thereby eliminating the need for the "temperature.txt" file.
+	* The image used by the websites (default: image.jpg) as well as all temporary files are now written to `allsky/tmp`.  **NOTE**: if you are using the Allsky Website you will need to change the "imageName" variable in `/var/www/html/allsky/config.js` to `"/current/tmp/"`.
+	* You can **significanly** reduce wear on your SD card by making `allsky/tmp` a [memory-based filesystem](https://github.com/thomasjacquin/allsky/wiki/Miscellaneous-Tips) for instructions).
