v3.1.1

Added the http.host and https.host standalone mode configuration options, defaulting to listen on 0.0.0.0 (all interfaces).

v3.1

• Added support for version 2.1 of the IIIF Image API.
  • Added support for the square region parameter to all processors.
  • Added the max size parameter.
  • Removed the information request Link header for the JSON-LD context.
  • Added the sizeByConfinedWh and sizeByDistortedWh feature names, supported by all processors.
  • Added the maxArea property to the profile description, based on the value of the max_pixels configuration key.
• Replaced the get_iiif2_service delegate method with extra_iiif2_information_response_keys.

v3.0.1

• Fixed a broken build in standalone mode. If you are running in a Servlet container, there is no need to update.

v3.0

• Added a Control Panel for web-based configuration changes.
• Changed the distribution archive to a custom .war file that can be run standalone (as before) or in a Servlet container.
• Added AmazonS3Cache.
• Added AzureStorageCache.
• Added redaction.
• Added the ability to restrict available sizes to those specified in the info.json response in the IIIF Image API 2.0 endpoint.
• Added an optional source image cache, which can improve the performance of StreamProcessors, as well as enable FileProcessors to work with StreamResolvers.
• Moved JdbcResolver delegate methods to the delegate script.
• Moved resolver-related delegate methods to submodules to improve organization.
• Changes to the logging configuration are applied immediately without restarting.
• Requests for more than max_pixels receive an HTTP 403 response rather than 500.
• Upgraded the Amazon S3 client to version 1.10.56.
• Upgraded the Restlet framework to version 2.3.7.

v2.2

• Added watermarking.
• Added PdfBoxProcessor.
• Added CacheWorker.
• Added AzureStorageResolver.
• Improved the performance of FilesystemCache under load.
• A FilesystemCache cache can be safely shared across multiple server instances.
• Improved the efficiency of JdbcCache.
• Added the -Dcantaloupe.cache.clean startup argument.
• Java2dProcessor and JaiProcessor support BigTIFF source images.
• Java2dProcessor uses a scale-appropriate source subsampling factor for improved performance at reduced scales.
• ImageMagickProcessor and GraphicsMagickProcessor support a custom background color with non-90°-multiple rotations, and use a transparent background for output formats that support it.
• IIIF information responses include native image tile sizes (or multiples), if available, and inverse multiple sizes, if not.
• The X-Forwarded-For header is respected.
• cache.server.resolve_first works with the IIIF Image API 1.1 endpoint.
• Redesigned the website.
• Moved documentation content to a versioned user manual.

2.1.1

• Fixed an HTTP 500 error when an invalid size parameter was used in an IIIF Image API endpoint.
• Fixed a bug in Java2dProcessor where an unnecessarily large TIFF pyramid level would be used when scaling by percent.
• Changed the JaiProcessor scaler to use nearest-neighbor interpolation in order to work around a bug in JAI.

2.1

• Added a delegate script method for authorization.
• Optimized JaiProcessor for tiled images.
• Made some aspects of JaiProcessor's JPEG and TIFF output configurable.
• Made Java2dProcessor's TIFF output compression configurable.
• Added SyslogAppenders for the application and access logs.
• Added support for sizeAboveFull.
• Changed the cache structure used by FilesystemCache to better accommodate large numbers of images.
• Fixed a SAXParserException in KakaduProcessor that could occur in OpenJDK 8.
• Upgraded JRuby to 9.0.5.0.
• Upgraded Restlet to 2.3.6.

2.0.1

• Fixed FilesystemCache failing to delete incompletely-written images (as due to e.g. a broken connection).
• Fixed a Java2dProcessor cropping bug affecting PNG and GIF source formats.
• Fixed a JaiProcessor scale-to-fit-inside bug.

2.0

• Redesigned internal APIs to abstract internal processing operations away from request processing directives and leverage Java NIO, where appropriate.
• Added an IIIF Image API 1.1 endpoint, moving the 2.0 endpoint to /iiif/2 to accommodate it.
• Added OpenJpegProcessor.
• Added support for SSL/TLS connections over HTTPS.
• Most configuration file changes are auto-detected and applied without restarting.
• Resolvers can be chosen dynamically using a custom Ruby delegate method.
• FilesystemResolver, HttpResolver, and AmazonS3Resolver can use a custom Ruby delegate method.
• Added support for custom service profiles in the IIIF Image API 2.0 information endpoint.
• Added configuration options to improve downscaling quality with Java2dProcessor and KakaduProcessor.
• Enhanced Java2dProcessor's efficiency with tiled source images.
• Added multi-resolution TIFF support to JaiProcessor.
• Improved the efficiency of KakaduProcessor and FfmpegProcessor.
• Improved the robustness of FilesystemCache.
• JdbcResolver and JdbcCache use a JDBC connection pool.
• JdbcCache uses transactions for nonatomic operations.
• Added an option to auto-purge missing (HTTP 404) images from the cache.
• Added an option to limit the pixel count of returned images, to prevent overloading the server.

1.2.1
