  * The latest value representations introduced in the DICOM standard are supported
  * for full changelog, see NEWS

- version 1.12.11
  * Lots of Bug- and CVE-Fixes. See News for details

Changes in orthanc-authorization:

- Version 0.12.0
  * Added support for inbox-links (new permission: create-inbox-links)

- version 0.11.4
  * Support new /tools/bulk-delete payload
  * New default permissions for DICOMWeb /qido & /retrieve routes.

- version 0.11.3
  * New default permissions for jobs

- Version 0.11.2
  * Now recording audit-logs when uploading a zip.
  * New default permissions for sending emails when sharing studies.
  * Added support for /tools/bulk-modify and /tools/bulk-anonymize
  * Fix: in /tools/bulk-delete, a user was able to delete resources
    he does not have access to.
  * Fix: in /tools/find, "ParentSeries" and "ParentStudy" fields were ignored.

Changes in orthanc-postgresql:

- version 10.3
  * Wait until Orthanc has finalized its startup before executing the
    DB HOUSEKEEPING task to avoid
    "Plugin trying to call the database during its initialization" errors.

- version 10.2
  * Internal changes only:
    - Enable linking with libpq18 (Ubuntu 26.04).
    - Show more details when an internal error occurs.

- version 10.1
  * 'minor changes' but no changelog

Changes in orthanc-dicomweb:

- version 1.24
  * Allow searching DICOM resources by "Study ID" in the DICOMweb client Web user interface.
  * New configuration option "OtherBinaryMode" to control how OB, OD,
    OF, OL, OV, or OW value representations are encoded in WADO-RS
    responses. Possible values: "BulkDataURI" (new default),
    "InlineBinary", "ArrayOfValues". Previous releases used the
    "ArrayOfValues" mode, which was valid but could be problematic for
    large datasets. (contribution by Yusuf Sayita, Philips)
  * Clarified error message when trying to access a single frame from a video in WADO-RS.
  * Fixed rendering of multiframe RGB48 images.
  * Fix: If the metadata cache attachment is missing from disk for a series, it is now generated again.

- version 1.23
  * If calling "/rendered" route on a Encapsulated PDF, the plugin will now return the PDF file
    instead of generating a 400 error.
  * Added metrics:
    - "orthanc_dicomweb_wadors_average_bandwidth_per_call_mbytes_per_second_5m" is the weighted
      average bandwidth of each individual call to any WADO-RS route to retrieve instances, series
      or studies. This metrics is only updated at the end of the call and averages the bandwidth
      values that are also displayed in the logs if "EnablePerformanceLogs" is set to "true".
    - "orthanc_dicomweb_wadors_total_bytes_transferred" counts the number of bytes that have
      been returned by any WADO-RS route to retrieve instances, series, or studies. This is
      updated while the response is returned.
  * "DicomWebStowClient" jobs now have their "Content.Resources" and "Content.Server" fields
    populated as soon as they are created, not only when they start being executed.

Affected product: orthanc. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
