v3.2

• Java 8 is now required.
• Significant efficiency improvements in the Java 2D processing pipeline affecting Java2dProcessor, JaiProcessor, and KakaduProcessor.
• All processors that use the Java 2D pipeline (Java2dProcessor, KakaduProcessor, OpenJpegProcessor, PdfBoxProcessor) support selectable upscaling and downscaling filters.
• Improved the scale quality of JaiProcessor.
• All processors offer configurable sharpening levels.
• Applicable processors respect source ICC color profiles.
• Added the option to copy EXIF, IPTC IIM, XMP, and/or native TIFF and PNG metadata from source images to derivative images of the same format, for some processors.
• Java2dProcessor and JaiProcessor respect the value of an embedded EXIF Orientation tag.
• Increased the default Java2dProcessor/JaiProcessor JPEG quality to 0.8 (80).
• Added support for a X-IIIF-ID request header, in order to return correct image identifiers in information responses whose requests have passed through a reverse proxy using a different identifier.
• Removed the JAI post-processor option for KakaduProcessor and OpenJpegProcessor.
• Zero-byte files are deleted when purging or cleaning FilesystemCache.
• KakaduProcessor and OpenJpegProcessor display a less inscrutable error message when they are unable to read a source file.
• HTTP 415 is returned instead of HTTP 400 when an output format is requested that is valid but unsupported by the current processor.
• Colorized the console application log.
• Console application log messages with a severity of WARN and above are routed to standard error.
• Upgraded a number of libraries.
