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

      • Enable linking with libpq18 (Ubuntu 26.04).
      • Show more details when an internal error occurs.

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.
