v4.2.0: 16-bit images and docker updates

Support has been added for images with 16 bits per channel (16 bits for grayscale, 48 bits for RGB, 64 bits for RGBA). Additionally, the docker compose setup has been updated for compose v2.

See the release notes for full details.

v4.1.4

This release updates dependencies to deal with minor security issues, fixes the s3demo, and improves how RAIS reports its version. See the full changelog for details

v4.1.3

Various "maintenance" changes: dependencies were updated, git-flow is no longer used, datadog is not a default plugin.

See the full changelog for all the details, including migration notes.

v4.1.1: Crash-on-exit fixed

This minor release removes a crash which occurred when exiting RAIS (e.g., via CTRL + C) and could prevent plugins from cleaning up

v4.1.0: ImageMagick fixes

Fixes ImageMagick crashes, particularly when handling large images

v4.0.2: MacOS Catalina fix, other minor fixes

The big fix is a build bug that was fixed by a contributor (thanks, @hejob!). Other minor fixes can be seen in our release notes

v3.3.2: Tile fix

This is a hotfix for v3, and probably the last fix for v3. This changes RAIS to not report tile sizes in the IIIF info.json response when an image has only one tile size in order to reduce some odd behavior in Open Seadragon

v4.0.1: Minor fixes

v4.0.1 fixes some minor issues:

• The TilePath configuration setting is now properly enforced - it cannot be blank or RAIS won't know where to find images using a file:// URL
• The main Docker image is now based on the golang image, meaning new builds will be compiled with the latest Go release rather than whatever's specified in the Dockerfile
• Local docker builds are now named more consistently with dockerhub images

v4.0.0: Cloud streaming, scheme mappings, fixes, and more!

RAIS v4.0.0 is the first major update in a very long time. The biggest features are that it can stream from cloud endpoints (such as S3) without a special plugin, and you can define your own schemes to make the final endpoints opaque (e.g., newyorktimes:// could map to a particular cloud provider or disk location).
