### Detailed list of changes
* Added a miximage generator that can be run automatically from the scraper and which includes comprehensive options, configurable from the menu
* Added an offline generator GUI for the miximage generator which can be used for bulk miximage generation without going via the scraper
* Added a fullscreen game media viewer
* Added a new video player based on FFmpeg
* Added a 60 FPS frame rate upscaler option to the video player which results in slightly smoother playback for low frame rate videos (e.g. 24 and 30 FPS)

* Added an option to limit the input in ES-DE to only the first controller (does not affect the emulators)
* Removed the startup notification regarding default keyboard mappings being in use, instead default mappings are now considered the recommended input configuration
* The controller input configuration is not automatically started any longer if there is no es_input.cfg file or if there are no applicable configuration entries in the file
* Increased the max allowed size for images when scraping, which should now only downscale files which really need it (like enormous marquee images when scraping from TheGamesDB)
* Increased the max allowed size for images when scraping, which should now only downscale files which really need it
* Changed the resampling algorithm for image downscaling for the scraper from bilinear to Lanczos which results in noticeably sharper images
* Added a configurable option to automatically retry scraping up to five times in case of ScreenScraper TLS errors (error message "SSL peer certificate or SSH remote key was not OK")
* Added a configurable option to automatically retry scraping up to eight times in case of ScreenScraper TLS errors
* Changed the button for jumping to a random system or game and added a setting for disabling the functionality altogether
* Added navigation sounds for some actions where it was missing, such as when attempting to add folders, placeholders or systems to custom collections
* Changed the custom collection "Jump to" navigation sound to the select sound instead of the scroll sound
@ -33,13 +35,17 @@
* Adjusted the size and position of the various menus to accomodate one additional entry on the screen
* The quit menu is now disabled by default, instead showing the "Quit EmulationStation" entry unless configured otherwise
* Changed the setting description for the favorites game toggling button
* Added the CImg library as a Git subtree (used by the miximage generator)
* Added the NanoSVG library as a proper Git subtree
* Changed the language standard from C++11 to C++14
### Bug fixes
* On Windows, images with Unicode characters in the game name that were resized when scraping would not be saved with valid filenames
* The glitches when configuring trigger buttons in GuiInputConfig have been fixed
* GuiDetectDevice wouldn't detect controller input that was of the 'axis' type (i.e. analog inputs)
* GuiInputConfig didn't correctly inform which buttons could be skipped for some rows
* The scraper would sometimes consider very small images to be invalid
* The Quick System Select help prompt was shown even when there was only a single game system present
* The "Y" button help prompt wasn't displayed correctly when using the Grid view style
* The debug logging for the analog controller inputs had some inconsistent signs

**Scrape 3D box images** _(ScreenScraper only)_
These images are currently unused, but will be used for future versions of ES-DE so it's recommended to keep this option enabled.
These images are primarily used for generating miximages, but they can also be viewed directly from the media viewer.
#### Miximage settings
These are the settings for the miximage generator, which can either be run from the scraper (single-game scraper or multi-scraper) or from the offline miximage generator. The miximages combines the screenshot, marquee and box images to make a composite picture that is displayed in the gamelist view. There are various settings for the generator.
**Miximage resolution**
It's possible to select betweeen 1280x960, 1920x1440 and 640x480 resolutions for the generated miximages. It's normally recommended to use the default option 1280x960 which gives good image quality without slowing down ES-DE too much. But for very weak machines, 640x480 may be a better option. However 1920x1440 is normally not recommended as it brings little quality improvements over 1280x960 and makes the gamelist browsing feel less responsive.
**Screenshot scaling method**
The _sharp_ scaling method uses nearest-neighbor interpolation which retains sharp pixels and looks better for most low-resolution retro games. The _smooth_ scaling method uses the Lanczos algorithm and produces smoother pixels. This may look better on some more modern games at higher resolutions. If unsure, use the _sharp_ method.
**Generate miximages when scraping**
Enables or disables the miximage generator when scraping. Applies to both the single-game scraper and the multi-scraper.
**Overwrite miximages (scraper/offline generator)**
Controls whether miximages should be overwritten or not. Note that the scraper setting _Overwrite files and data_ does not affect the miximages.
**Remove letterboxes from screenshots**
With this option enabled, any horizontal pure black areas at the top and bottom of the screenshots are automatically cropped.
**Remove pillarboxes from screenshots**
With this option enabled, any vertical pure black areas at the left and right sides of the screenshots are automatically cropped.
**Incude marquee image**
Whether to include the marquee (wheel) image in the composite miximage.
**Incude box image**
Whether to include the box image in the composite miximage. If a 3D box exists for the game, this will be used.
**Use cover image if 3D box is missing**
Whether to use the 2D box cover as fallback if the 3D box image is missing for the game.
**Offline generator**
This is not a setting, but instead a GUI to generate miximages offline without going via the scraper. This tool uses the same game system selections as the scraper, so you need to select at least one system on the scraper menu before attempting to run it. All the miximage settings are applied in the same way as when generating images via the scraper. The prerequisite is that at least a screenshot exists for each game. If there is no screenshot, or if the screenshot is unreadable for some reason, the generation for that specific game will fail. There is statistics shown in the tool displaying the number of generated, overwritten, skipped and failed images. Any error message is also shown on screen as well as being saved to the es_log.txt file.

**Overwrite files and data**
Affects both overwriting of metadata as well as actual game media files on the filesystem. Even with this option disabled, metadata entries which are set to their default values will of course be populated by the scraper. In other words, this option only affects overwriting of previously scraped data. Game names are considered as set to their default vaules if either corresponding to the physical game file on disk minus the extension (e.g. the entry _Commando_ if the file is named _Commando.zip_), or for arcade games if corresponding to the MAME names as defined in the bundled mamenames.xml.
