v0.8.0

DICOM-rs 0.8.0

This is a major release of DICOM-rs, boasting an ample collection of new capabilities. Highlights are async support for network applications (via Tokio), and support for a bunch of new transfer syntaxes, including the brand new one for JPEG XL!
Images in JPEG-LS, High Throughput JPEG 2000 (HTJ2K), and JPEG XL can now be decoded, and pixel data can be encoded to JPEG-LS and JPEG XL Lossless.

Changes

• A minimal Rust compiler version policy is now implemented (#587 @qarmin)
  • 1.72.0 is the minimum version supported by all library crates with the default features. Binary crates or additional features may affect compatibility and require a more recent version of the compiler.
• [ul,storescp,storescu] New async implementation of dicom_ul, with application in tools dicom-storescu and dicom-storescp. (#542 @naterichman)

v0.7.0

DICOM-rs 0.7.0

Today a major edition of DICOM-rs is released. Version 0.7.0 encompasses a new array of changes to correct existing quirks in the API and make way for grater capabilities. It is also not without new features, improvements and a few bug fixes.

This is to reduce the confusion of certain crates in the ecosystem appearing to be outdated when they are not, as well as to better clarify which versions are expected to be compatible with which crate in the ecosystem.

• dicom-core 0.7.0
• dicom-dictionary-std 0.7.0
• dicom-encoding 0.7.0
• dicom-parser 0.7.0

Full Changelog: v0.6.3...v0.7.0

v0.6.3

DICOM-rs 0.6.3

This patch release intends to fix and mitigate some issues found in the previous version.

One particular concern raised since version 0.6.2 was that the project does not build when targeting Windows platforms unless the Cargo features are adjusted to exclude openjp2.
While fixing this entirely would incur a breaking change too early in the project's release cycle, this patch release will hopefully help guide Windows developers into building all crates in the DICOM-rs ecosystem, until the next major version arrives.

If your building target is any of the Windows platforms (such as x86_64-pc-windows-msvc or x86_64-pc-windows-gnu), you will need to disable the default Cargo features and explicitly add the ones that you may need. The default_windows feature has been added for convenience.

cargo build --release --no-default-features --features=cli,default_windows,backtraces,openjpeg-sys

Fixes

• [pixeldata] Fix and improve single-frame pixel data decoding via GDCM (#422 @dougyau)
