Pending changes in the mainline
===============================


Version 1.12.5 (2024-12-17)
===========================

General
-------

* Database:
  - Introduced the database optimization "ExtendedFind" to replace many small SQL queries
    by a single, large SQL query. This can greatly reduce the cost related to latency
    when working with large databases (e.g., if using PostgreSQL).
    Furthermore, "ExtendedFind" brings new sorting and filtering features to the
    REST API, mainly in "/tools/find".
  - Introduced the new database primitive "ExtendedChanges" to allow filtering on "/changes".
  - Reduced the number of SQL queries when ingesting DICOM files.
* Introduced a new configuration "ReadOnly" to forbid an Orthanc instance to perform
  any modification to the index database or to the storage area.
  

REST API
--------

* API version upgraded to 26
* Support HTTP "Range" request header on "{...}/attachments/{...}/data" and
  "{...}/attachments/{...}/compressed-data"
* Improved parsing of multiple numerical values in DICOM tags
  https://discourse.orthanc-server.org/t/qido-includefield-with-sequences/4746/6
* In "/system", added a new field "Capabilities" with new values:
  - "HasExtendedChanges" if the index database provides this optimization
  - "HasExtendedFind" if the index database provides this primitive
* If the index database provides the "HasExtendedChanges" primitive, "/changes"
  supports two additional arguments:
  - "type" to filter the changes returned by the query
  - "to" to possibly cycle through changes in reverse order
  Example: "/changes?type=StableStudy&to=7584&limit=100"
* If the index database provides the "HasExtendedFind" primitive, "/tools/find"
  supports new options:
  - "OrderBy" to order by DICOM tag or metadata value
  - "ParentPatient", "ParentStudy", and "ParentSeries" to retrieve only descendants of a
    given DICOM resource
  - "MetadataQuery" to filter results based on metadata values
  - "ResponseContent" to define what shall be included in the response for each returned
    resource (e.g: Metadata, Children,...)
* In "/tools/find", the "Limit" and "Since" arguments are not allowed anymore if the
  query requests filtering on DICOM tags that are not stored in the index database
* The new "/tools/count-resources" API route is similar to "tools/find" but only
  returns the number of resources matching the criteria
* "/studies?since=x&limit=0" and similar routes for patients, series, and instances:
  "limit=0" now means "no limit" instead of "no results" as in previous versions of Orthanc
* In DICOMweb JSON, the "DS - Decimal String" values were previously represented as float
  numbers, but are now represented as strings to avoid introduction of long float representation
  (e.g 0.1429999999999 vs "0.143") and to be compliant with the DICOMweb standard:
  https://dicom.nema.org/medical/dicom/current/output/chtml/part18/sect_F.2.3.html
  This has no impact on the Stone Web viewer and OHIF:
  https://discourse.orthanc-server.org/t/dicomwebplugin-does-not-return-series-metadata-properly/5195


Maintenance
-----------

* DICOM TLS: "DicomTlsTrustedCertificates" is not required anymore when issuing
  an outgoing SCU connection if "DicomTlsRemoteCertificateRequired" is set to "false"
* Fix C-Find queries not returning computed tags such as ModalitiesInStudy,
  NumberOfStudyRelatedSeries,... in very specific use cases
* Fix C-Find queries not returning private tags in the modality worklist plugin
* Fix an extremely rare error when 2 threads are trying to create the same folder
  in the File Storage at the same time
* Fix crashes if handling very large images
* Fix deadlock when parsing specific invalid DICOM files
* Loading plugins: Orthanc will now fail to start when provided with a plugin path
  that can not be found
* Metrics:
  - Fix a few metrics that were not published
  - Added 2 metrics: "orthanc_storage_cache_miss_count" and "orthanc_storage_cache_hit_count"
* Added a new fallback when trying to decode a frame: transcode the file using the plugin
  before decoding the frame. This solves some issues with JP2K Lossy compression:
  https://discourse.orthanc-server.org/t/decoding-displaying-jpeg2000-lossy-images/5117
* Added new warnings that can be disabled in the configuration: 
  - W003_DecoderFailure
  - W004_NoMainDicomTagsSignature
  - W005_RequestingTagFromLowerResourceLevel
  - W006_RequestingTagFromMetaHeader
  - W007_MissingRequestedTagsNotReadFromDisk
* New default MainDicomTags are now stored in the DB:
  - At Study Level:
    - TimezoneOffsetFromUTC (used in QIDO-RS default queries)
  - At Series Level:
    - TimezoneOffsetFromUTC (used in QIDO-RS default queries)
    - PerformedProcedureStepStartDate (used in QIDO-RS default queries)
    - PerformedProcedureStepStartTime (used in QIDO-RS default queries)
    - RequestAttributesSequence (used in QIDO-RS default queries)
  - Note that, in order to access these values for resources that were ingested in Orthanc
    before this release, you will have to run the Housekeeper plugin or to call
    "/reconstruct" on every resource
* Upgraded dependencies for static builds:
  - boost 1.86.0
  - curl 8.9.0
  - SQLite 3.46


Version 1.12.4 (2024-06-05)
===========================

REST API
--------

* API version upgraded to 24
* Added "MaximumPatientCount" in /system
* Added a new "LimitToThisLevelMainDicomTags" field in the payload of 
  /patients|studies|series/instances/../reconstruct to speed up the reconstruction
  in case you just want to update the MainDicomTags of that resource level only 
  (e.g., after you have updated the "ExtraMainDicomTags" for this level)
* The "requestedTags" GET argument is deprecated in favor of "requested-tags"
* Added "?whole" option to "/instances/{id}/tags" to access tags stored after pixel data

Plugins
-------

* Multitenant DICOM plugin: added support for locales.
* Housekeeper plugin: 
  - Added an option "LimitMainDicomTagsReconstructLevel"
    (allowed values: "Patient", "Study", "Series", "Instance"). This can greatly speed
    up the housekeeper process, e.g. if you have only updated the Study level ExtraMainDicomTags.
  - Fixed broken /instances/../tags route after running the Housekeeper
    after having changed the "IngestTranscoding".
* SDK: added OrthancPluginLogMessage() as a new primitive for plugins
  to log messages. This new primitive will display the plugin name,
  the plugin file name, and the plugin line number in the logs. If
  they are not using the LOG() facilities provided by the
  OrthancFramework, plugins should now use ORTHANC_PLUGINS_LOG_INFO(),
  ORTHANC_PLUGINS_LOG_WARNING(), and ORTHANC_PLUGINS_LOG_ERROR().

Maintenance
-----------

* C-Find queries:
  - In C-Find queries including "GenericGroupLength" tags, Orthanc was still
    extracting these tags from the storage although they were already ignored
    and not returned in the response.
    They are now removed from the query earlier to avoid this disk access that
    could slow down the response time. Note that this seems to happen mainly
    when the query originates from some GE devices (AWS).
  - "TimezoneOffsetFromUTC" is now ignored for matching.
* The 0x0111 DIMSE Status is now considered as a warning instead of an error
  when received as a response to a C-Store.
  See https://discourse.orthanc-server.org/t/ignore-dimse-status-0x0111-when-sending-partial-duplicate-studies/4555/3
* Removed potential PHI from the logs when Orthanc encounters an error while
  creating a ZIP archive.
* Monitoring of stable resources now also takes into consideration the
  resource type, not only the resource identifier identifier.
* DICOM TLS:
  - In prior versions, when "DicomTlsRemoteCertificateRequired" was set to false, Orthanc
    was still sending a client certificate request during the TLS handshake but was not
    triggering and error if the client certificate was not trusted (equivalent to the
    "--verify-peer-cert" DCMTK option). Starting with Orthanc 1.12.4, if this option is
    set to "false", Orthanc will not send a client certificate request during the TLS
    handshake anymore (equivalent to the "--ignore-peer-cert" DCMTK option).
  - When working with "DicomTlsEnabled": true and "DicomTlsRemoteCertificateRequired": false,
    Orthanc was refusing to start if no "DicomTlsTrustedCertificates" was provided.
  - New configuration options:
    - "DicomTlsMinimumProtocolVersion" to select the minimum TLS protocol version
    - "DicomTlsCiphersAccepted" to fine tune the list of accepted ciphers
* Fixed broken /instances/../tags route after calling of
  /studies/../reconstruct after having changed the "IngestTranscoding".
* Upgraded dependencies for static builds:
  - boost 1.85.0


Version 1.12.3 (2024-01-31)
===========================

General
-------

* Performance of databases:
  - At startup, if using a database plugin, displays the latency to access the DB.
  - Added support for new DB primitives to enable the "READ COMMITTED"
    transaction mode in the PostgreSQL plugin.

REST API
--------

* API version upgraded to 23
* Added a 'KeepLabels' option in /modify routes (default = false)

Maintenance
-----------

* Upgraded dependencies for static builds:
  - boost 1.84.0
  - curl 8.5.0
  - dcmtk 3.6.8
  - jsoncpp 1.9.5
  - libjpeg 9f
  - libpng 1.6.40
  - openssl 3.1.4
  - pugixml 1.14
  - zlib 1.3.1


Version 1.12.2 (2023-12-19)
===========================

General
-------

* Performance:
  - Allow multiple plugins to use the plugin SDK at the same time.  In previous versions,
    functions like instance transcoding or instance reading where mutually exclusive.
    This can bring some significant improvements, especially in viewers.
  - Optimized the StorageCache to prevent loading the same file multiple times if
    multiple users request the same file at the same time.
  - The StorageCache is now also storing transcoded instances that have been requested by /file?transcode=...
    that is now used by the DICOMweb plugin.  This speeds up retrieval of transcoded frames through WADO-RS.
  - Now displaying timings when reading from/writing to disk in the verbose logs.
* HTTP compression:
  - The default value of the "HttpCompressionEnabled" is now false by default.  This reduces
    the Orthanc overall CPU usage and latency.  This is suitable for setups with large  
    bandwidth network like LAN.
  - When "HttpCompressionEnabled" is true, only the content that is clearly identified as
    compressible is compressed (JSON, XML, HTML, text, ...).  DICOM files are never
    compressed over HTTP.  In prior versions, all content types were compressed.
    This notably greatly improves loading time of large DICOM 
    files through WADO-RS e.g in StoneViewer when working on large bandwidth networks.
  - When "HttpCompressionEnabled" is true, content < 2KB are never compressed.
* Logs:
  - Each line of log now contains the name of the thread that is logging the message.
    A new "--logs-no-thread" command line option can be used to get back to the previous behavior to
    keep backward compatibility.

REST API
--------

* API version upgraded to 22
* Added a route to delete completed jobs from history: DELETE /jobs/{id}
* Added a "transcode" option to the /file route:
  e.g: /instances/../file?transcode=1.2.840.10008.1.2.4.80
* now accepting GET requests on these 3 routes to create archive/media:
  /tools/create-archive?resources=..,..2&transcode=1.2.840.10008.1.2.4.80
  /tools/create-media?resources=..,..2&transcode=1.2.840.10008.1.2.4.80
  /tools/create-media-extended?resources=..,..2&transcode=1.2.840.10008.1.2.4.80
* All "expand" GET arguments now accepts "expand=true" and "expand=false" values.
  The /studies/../instances and sibling routes are the only whose expand is true if not specified.
  These routes now accepts "expand=false" to simply list the child resources ids.
* In /tools/metrics-prometheus:
  - "orthanc_dicom_cache_size" renamed as "orthanc_dicom_cache_size_mb"
  - added "orthanc_storage_cache_count" and "orthanc_storage_cache_size_mb"

Plugins
-------

* Housekeeper plugin:
  - Update to rebuild the cache of the DICOMweb plugin when updating to DICOMweb 1.15.
  - New trigger configuration: "DicomWebCacheChange"
  - Fixed reading the triggers configuration.
  - Introduced a "sleep" to lower CPU usage when idle.
* Plugins are now allowed to modify/delete private metadata/attachments
  (i.e. whose identifiers are < 1024)
* Added "OrthancPluginSetCurrentThreadName()" in the plugin SDK.

Maintenance
-----------

* Fix unit test PngWriter.Color16Pattern on big-endian architectures,
  as suggested by Etienne Mollier: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1041813
* Prevent the leak of the full path of the source files in the binaries
* Fix loading of DCMTK dictionary in the MultitenantDicom plugin when built dynamically:
  https://discourse.orthanc-server.org/t/dimse-failure-using-multitenant-plugin/3665
* Support multiple values in SpecificCharacterSet in C-Find answers:
  https://discourse.orthanc-server.org/t/c-find-fails-on-unknown-specific-character-set-iso-2022-ir-6-iso-2022-ir-100/3947
* When exporting a study archive, make sure to use the PatientName from the study and not from the patient
  in case of PatientID collision.
* DICOM C-Store:
  - Avoid some unnecessary renegotiation of DICOM association.
  - Force renegotiation in case no presentation context were accepted in previous association (we have
    observed PACS that were not consistent in the accepted presentation contexts)
  - Improved logging
* Solved a deadlock related to the Job Engine events and plugins.  Job events are now pushed
  into a queue to be handled asynchronously by plugins.
* ZIP of studies whose PatientName and PatientID did not contain any ASCII character are now valid.
* Upgraded minizip library to stay away from CVE-2023-45853 although Orthanc is likely not affected since ZIP
  filenames are based on DICOM Tag values whose length is limited in size.
  Great thanks to James Addison for notifying us about the vulnerability and patch to apply !
* Fix XSS in Orthanc error reporting (as reported by Sébastien Doria, Vumetric Cybersecurity) by:
  - always including a "Content-Type" header in HTTP responses with a body.
  - always including "X-Content-Type-Options: nosniff"
* Upgraded dependencies for static builds:
  - boost 1.83.0


Version 1.12.1 (2023-07-04)
===========================

General
-------

* Orthanc now anonymizes according to Basic Profile of PS 3.15-2023b Table E.1-1
* Added metrics:
  - "orthanc_storage_read_bytes" 
  - "orthanc_storage_written_bytes"
  - "orthanc_memory_trimming_duration_ms"

REST API
--------

* API version upgraded to 21
* "/tools/create-dicom" can now be used to create Encapsulated 3D
  Manufacturing Model IODs (MTL, OBJ, or STL)
* Added a route to delete the output of an asynchronous job (right now
  only for archive jobs): e.g. DELETE /jobs/../archive

Plugins
-------

* Added "OrthancPluginLoadDicomInstance()" to load DICOM instances from the database
* Added "OrthancPluginSetMetricsIntegerValue()" to track metrics with integer values

Maintenance
-----------

* Fix decoding of YBR_FULL RLE images for which the "Planar Configuration" 
  tag (0028,0006) equals 1
* Made Orthanc more resilient to common spelling errors in SpecificCharacterSet
* Modality worklists plugin: Allow searching on private tags (exact match only)
* Fix orphan files remaining in storage when working with MaximumStorageSize
  (https://discourse.orthanc-server.org/t/issue-with-deleting-incoming-dicoms-when-maximumstoragesize-is-reached/3510)
* When deleting a resource, the "LastUpdate" metadata of its parents are now updated
* Reduced the memory usage when downloading archives when "ZipLoaderThreads" > 0
* Metrics can be stored either as floating-point numbers, or as integers
* Reduce the frequency of memory trimming from 100ms to 30s to avoid high idle
  CPU load (https://discourse.orthanc-server.org/t/onchange-callbacks-and-cpu-loads/3534).
* Upgraded dependencies for static builds:
  - boost 1.82.0


Version 1.12.0 (2023-04-14)
===========================

General
-------

* Support for labels associated with patients, studies, series, and instances
* Added a sample plugin bringing multitenant DICOM support through labels

REST API
--------

* API version upgraded to 20
* New URIs "/.../{id}/labels/{label}" to test/set/remove labels
* "/patients/{id}", "/studies/{id}", "/series/{id}" and "/instances/{id}"
  contain the "Labels" field
* "/tools/find" now accepts the "Labels" and "LabelsConstraint" arguments
* "/tools/labels" lists all the labels that are associated with any resource
* "/system": added "UserMetadata" and "HasLabels"
* Added option "?numeric" if listing metadata

Plugins
-------

* Added "OrthancPluginRegisterDatabaseBackendV4()" to communicate using Google
  Protocol Buffers between the Orthanc core and database plugins

Orthanc Explorer
----------------

* Added support for labels
* Added buttons to copy the URL of ZIP archives and DICOM files to the clipboard

Maintenance
-----------

* Enforce the existence of the patient/study/instance while creating its archive
* Security: New configuration option "RestApiWriteToFileSystemEnabled"
  to allow "/instances/../export" (the latter is now disabled by default)
* Fix issue 214: VOILUTSequence is not returned in Wado-RS
* Fix /tools/reset crashing when ExtraMainDicomTags were defined
* Fix Housekeeper plugin infinite loop if Orthanc is empty.
* Fix a crash in /tools/reconstruct triggered by the Housekeeper plugin 
  when only changing the StorageCompression.
* Avoid the use of "externalproject_add()" to build the sample plugins
* Upgraded dependencies for static builds:
  - openssl 3.1.0


Version 1.11.3 (2023-02-03)
===========================

General
-------

* C-Store SCU now gives priority to the preferred TransferSyntax
  proposed by the receiving SCP instead of Orthanc own
  AcceptedTransferSyntaxes.
* Made the default SQLite DB more robust wrt future updates like
  adding new columns in DB.
* Made the HTTP Client errors more verbose by including the URL in the logs.
* Optimization: now using multiple threads to transcode files for
  asynchronous download of studies archive.
* New configuration "KeepAliveTimeout" with a default value of 1 second.
* ResourceModification jobs (/modify + /anonymize) can now use multiple threads to speed up processing
  - New configuration "JobsEngineThreadsCount.ResourceModification" to configure the number of threads.
* For systems using glibc > 2.8 (most of Linux systems except LSB
  binaries): Introduced a new thread for to trim memory in Orthanc (different
  from the Housekeeper sample plugin). This thread regularly try to
  give back memory that Orthanc no longer uses to the system. This
  reduces the overall memory consumption. More information in
  OrthancServer/Resources/ImplementationNotes/memory_consumption.txt.

REST API
--------

* API version upgraded to 19
* Loosen the sanity checks for DICOM modifications, if "Force" option is given:
  - allow modification of PatientID at study level
  - allow modification of PatientID, StudyInstanceUID at series level
  - allow modification of PatientID, StudyInstanceUID, SeriesInstanceUID at instance level
  - allow modification of a patient without changing her PatientID
  Added sanity checks for modifications to make sure the user preserves the DICOM model when modifying high level tags.
    E.g. if you modify the PatientID at study level, also make sure to modify all other Patient related
    tags (PatientName, PatientBirthDate, ...)
* Automatically reconstruct the modified resources at the end of the DICOM modifications job to ensure
  improved consistency of the DICOM model.
* If specifying 'Transcode' option to /modify or /anonymize, this value will take over the 'IngestTranscoding'
  global configuration
* Allow the HTTP server to return responses > 2GB (fixes asynchronous download of zip studies > 2GB)
* /modalities/.../store now accepts "CalledAet", "Host", "Port" to override the modality configuration 
  from the configuration file for a specific operation.
* /tools/metrics-prometheus: added orthanc_last_change and orthanc_up_time_s
* Tolerance for "image/jpg" MIME type instead of "image/jpeg" in /tools/create-dicom
* /system: added MaximumStorageMode and MaximumStorageSize

Plugins
-------

* Added a "header" argument to all OrthancPeers::DoPost, DoPut, ... in the "OrthancPluginCppWrapper"
* Added "OrthancPluginCreateJob2()" in the plugin SDK to avoid
  possible crashes when "OrthancPluginJobGetContent()" or
  "OrthancPluginJobGetSerialized()" get called

Maintenance
-----------

* Fix decoding of RLE images for which the "Planar Configuration" tag (0028,0006) equals 1
* Fix issue #212 (Anonymization process transcodes data and loses resource link).


Version 1.11.2 (2022-08-30)
===========================

General
-------

* Added support for RGBA64 images in tools/create-dicom and /preview
* New configuration "MaximumStorageMode" to choose between recyling of
  old patients (default behavior) and rejection of new incoming data when
  the MaximumStorageSize has been reached.

Bug Fixes
---------

* Fix the "Never" option of the "StorageAccessOnFind" that was sill accessing
  files (bug introduced in 1.11.0).
* Fix the Storage Cache for compressed files (bug introduced in 1.11.1).

Maintenance
-----------

* DelayedDeletion plugin: Fix leaking of symbols
* SQLite now closes and deletes WAL and SHM files on exit.  This should improve
  handling of SQLite DB over network drives.
* Fix static compilation of boost 1.69 on Ubuntu 22.04
* Upgraded dependencies for static builds:
  - boost 1.80.0
  - dcmtk 3.6.7  (fixes CVE-2022-2119 and CVE-2022-2120)
  - openssl 3.0.5


Version 1.11.1 (2022-06-30)
===========================

General
-------

* New sample plugin: "DelayedDeletion" that will delete files from disk
  asynchronously to speed up deletion of large studies.
* Lua: new "SetHttpTimeout" function
* Lua: new "OnHeartBeat" callback called at regular interval provided that
       you have configured "LuaHeartBeatPeriod" > 0.
* "ExtraMainDicomTags" configuration now accepts Dicom Sequences.  Sequences are
  stored in a dedicated new metadata "MainDicomSequences".  This should improve
  DicomWeb QIDO-RS and avoid warnings like "Accessing Dicom tags from storage when 
  accessing series : 0040,0275".
  Main dicom sequences can now be returned in "MainDicomTags" and in "RequestedTags".

Bug Fixes
---------

* Fix the storage cache that was not used by the Plugin SDK.  This fixes the 
  DicomWeb plugin "/rendered" route performance issues.

Maintenance
-----------

* Housekeeper plugin: Fix resume of previous processing
* Added missing MOVEPatientRootQueryRetrieveInformationModel in 
  DicomControlUserConnection::SetupPresentationContexts()
* Improved HttpClient error logging (add method + URL)

REST API
--------

* API version upgraded to 18
* /system is now reporting "DatabaseServerIdentifier"
* Added an Asynchronous mode to /modalities/../move.
* "RequestedTags" option can now include DICOM sequences.

Plugins
-------

* New function in the SDK: "OrthancPluginGetDatabaseServerIdentifier"

OrthancFramework (C++)
----------------------

* DicomMap::ParseMainDicomTags has been deprecated -> retrieve "full" tags
  and use DicomMap::FromDicomAsJson instead


Version 1.11.0 (2022-05-09)
===========================

General
-------

* New configuration "ExtraMainDicomTags" to store more tags in the Index DB
  to speed up, e.g, building C-Find, dicom-web or tools/find answers
* New sample plugin: "Housekeeper" that will re-construct the DB/Storage
  when it detects there is room for improvements, e.g:
  - if files were stored with a version of Orthanc prior to 1.9.1,
    the storage might still contain dicom-as-json files that are not needed
    anymore -> it will remove them
  - if "ExtraMainDicomTags" has changed.
  - if "StorageCompression" or "IngestTranscoding" has chagned.
* New configuration "Warnings" to enable/disable individual warnings that can
  be identified by a W0XX prefix in the logs.
  These warnings have been added:
  - W001_TagsBeingReadFromStorage
  - W002_InconsistentDicomTagsInDb
* C-Find and QIDO-RS can now return the InstanceAvailability tag.  Value is 
  always "ONLINE"
* Improved decoding of US Images with Implicit VR.
* Speed-up handling of DicomModalitiesInStudy in C-Find and tools/find queries.

REST API
--------

* API version upgraded to 17
* new options in tools/find:
  - "RequestedTags" (to use together with "Expand": true) contains a list of tags 
    that you'll receive in the "RequestedTags" field in the answers.  These tags
    may be tags from the MainDicomTags in DB, from the DICOM file or 'computed'
    like ModalitiesInStudy.  Check the new configuration "ExtraMainDicomTags" and
    "Warnings" to optimize your queries.
* new query argument "requestedTags" in all API routes listing resources:
  - /patients, /patients/../studies, /patients/../series, /patients/../instances
  - /studies, /studies/../series, /studies/../instances
  - /series, /series/../instances
  - /instances
  ex:
  - /studies/c27857df-4078c84c-1a79ea78-ac357bb2-9dadc119?requestedTags=ModalitiesInStudy
  - /studies?expand&since=0&limit=10&requestedTags=ModalitiesInStudy
  
* /reconstruct routes:
  - new options "ReconstructFiles" (false by default to keep backward compatibility) to 
    potentialy compress/uncompress the files or transcode them if "StorageCompression"
    or "IngestTranscoding" has changed since the file has been ingested.
  POSSIBLE BREAKING-CHANGES:
  - the /reconstruct routes now preserve all metadata
  - the /reconstruct routes now skip the IncomingInstanceFilter
  - the /reconstruct routes won't generate new events like NewStudy, StableStudy, ...
    therefore, the corresponding callbacks won't be called anymore
  - the /reconstruct routes won't affect the patient recycling anymore
* new fields reported in the /system route:
  - "MainDicomTags" to list the tags that are saved in DB
  - "StorageCompression", "OverwriteInstances", "IngestTranscoding" reported from the 
    configuration file
* New option "filename" in "/.../{id}/archive" and "/.../{id}/media" to
  manually set the filename in the "Content-Disposition" HTTP header


Version 1.10.1 (2022-03-23)
===========================

General
-------

* Improved DICOM authorization checks when multiple modalities are
  declared with the same AET.

Plugins
-------

* New function in the SDK: "OrthancPluginRegisterWebDavCollection()"
  to map a WebDAV virtual filesystem into the REST API of Orthanc.

Documentation
-------------

* Removed the "LimitJobs" configuration that is not used anymore since
  the new JobEngine has been introduced (in Orthanc 1.4.0). The
  pending list of jobs is unlimited.


Version 1.10.0 (2022-02-23)
===========================

General
-------

* New configuration "DicomAlwaysAllowFindWorklist" to complement the existing
  "DicomAlwaysAllowFind" configuration.  "DicomAlwaysAllowFind" applies now 
  only to C-Find for Patients/Studies/Series/Instances while C-Find for worklists are
  covered by "DicomAlwaysAllowFindWorklist".  The same changes applies to new 
  configurations in "DicomModalities": "AllowFind" is now complemented by 
  "AllowFindWorklist".
  This new option allows improved security management.  E.g: a modality might have
  only "AllowStore" and "AllowFindWorklist" enabled but might have "AllowFind"
  disabled to prevent listing past patient studies.
  Possible BREAKING-CHANGE: if you relied on "DicomAlwaysAllowFind" or "AllowFind"
  to specifically authorize C-Find for worklist, you now need to explicitly enable
  "DicomAlwaysAllowFindWorklist" and/or "AllowFindWorklist"
