+Version 1.15 (2023-08-24)
+=========================
+
+* speed improvement:
+  - Now storing the output of /dicom-web/studies/../series/../metadata route in an attachment that can be used
+    by the "Full" mode.
+    The json file is gzipped and stored in attachment 4301 everytime a series is stable or the first time
+    its /dicom-web/studies/../series/../metadata route is called in "Full" mode if the attachment does not exist yet.
+    A new route /studies/{orthancId}/update-dicomweb-cache has also been added to allow e.g. the Housekeeper plugin
+    to generate these attachment for old studies.
+    This cache can be disabled by setting "EnableMetadataCache" to false.  However, disabling the cache
+    won't delete the already cached data.  You may call DELETE /series/../attachments/4031 to clear the cache.
+
+Version 1.14 (2023-07-05)
+=========================
+
+* speed improvements:
+  - Speeded up instance metadata retrieval using OrthancPluginLoadDicomInstance() from SDK 1.12.1
+  - Using multiple threads to compute the studies/../series/../metadata route when in "Full" mode.
+    New configuration: "MetadataWorkerThreadsCount" defaults to 4
+  - Small speed-up the studies/../series/../metadata route when in "MainDicomTags" mode.
+* Support "X-Forwarded-Host" and "X-Forwarded-Proto" headers to compute BulkDataURI.
+* Fix issue #216 (Requests fail due to bad parsing of the accept HTTP header (semi-colons))
+
+
+Version 1.13 (2023-02-03)
+=========================
+
+* Use Orthanc SDK 1.11.3 to avoid a crash in STOW-RS jobs.
+
+
+Version 1.12 (2022-10-27)
+=========================
+
+* STOW-RS now calls to the plugin flavored /instances route and now also forwards
+  the HTTP headers from the Incoming STOW-RS request.

+/**
+ * \mainpage
+ *
+ * This C/C++ SDK allows external developers to create plugins that
+ * can be loaded into Orthanc to extend its functionality. Each
+ * Orthanc plugin must expose 4 public functions with the following
+ * signatures:
+ * 
+ * -# <tt>int32_t OrthancPluginInitialize(const OrthancPluginContext* context)</tt>:
+ *    This function is invoked by Orthanc when it loads the plugin on startup.
+ *    The plugin must:
+ *    - Check its compatibility with the Orthanc version using
+ *      ::OrthancPluginCheckVersion().
+ *    - Store the context pointer so that it can use the plugin 
+ *      services of Orthanc.
+ *    - Register all its REST callbacks using ::OrthancPluginRegisterRestCallback().
+ *    - Possibly register its callback for received DICOM instances using ::OrthancPluginRegisterOnStoredInstanceCallback().
+ *    - Possibly register its callback for changes to the DICOM store using ::OrthancPluginRegisterOnChangeCallback().
+ *    - Possibly register a custom storage area using ::OrthancPluginRegisterStorageArea2().
+ *    - Possibly register a custom database back-end area using OrthancPluginRegisterDatabaseBackendV3().
+ *    - Possibly register a handler for C-Find SCP using OrthancPluginRegisterFindCallback().
+ *    - Possibly register a handler for C-Find SCP against DICOM worklists using OrthancPluginRegisterWorklistCallback().
+ *    - Possibly register a handler for C-Move SCP using OrthancPluginRegisterMoveCallback().
+ *    - Possibly register a custom decoder for DICOM images using OrthancPluginRegisterDecodeImageCallback().
+ *    - Possibly register a callback to filter incoming HTTP requests using OrthancPluginRegisterIncomingHttpRequestFilter2().
+ *    - Possibly register a callback to unserialize jobs using OrthancPluginRegisterJobsUnserializer().
+ *    - Possibly register a callback to refresh its metrics using OrthancPluginRegisterRefreshMetricsCallback().
+ *    - Possibly register a callback to answer chunked HTTP transfers using ::OrthancPluginRegisterChunkedRestCallback().
+ *    - Possibly register a callback for Storage Commitment SCP using ::OrthancPluginRegisterStorageCommitmentScpCallback().
+ *    - Possibly register a callback to keep/discard/modify incoming DICOM instances using OrthancPluginRegisterReceivedInstanceCallback().
+ *    - Possibly register a custom transcoder for DICOM images using OrthancPluginRegisterTranscoderCallback().
+ *    - Possibly register a callback to discard instances received through DICOM C-STORE using OrthancPluginRegisterIncomingCStoreInstanceFilter().
+ *    - Possibly register a callback to branch a WebDAV virtual filesystem using OrthancPluginRegisterWebDavCollection().
+ * -# <tt>void OrthancPluginFinalize()</tt>:
+ *    This function is invoked by Orthanc during its shutdown. The plugin
+ *    must free all its memory.
+ * -# <tt>const char* OrthancPluginGetName()</tt>:
+ *    The plugin must return a short string to identify itself.
+ * -# <tt>const char* OrthancPluginGetVersion()</tt>:
+ *    The plugin must return a string containing its version number.
+ *
+ * The name and the version of a plugin is only used to prevent it
+ * from being loaded twice. Note that, in C++, it is mandatory to
+ * declare these functions within an <tt>extern "C"</tt> section.
+ * 
+ * To ensure multi-threading safety, the various REST callbacks are
+ * guaranteed to be executed in mutual exclusion since Orthanc
+ * 0.8.5. If this feature is undesired (notably when developing

+/**
+ * \mainpage
+ *
+ * This C/C++ SDK allows external developers to create plugins that
+ * can be loaded into Orthanc to extend its functionality. Each
+ * Orthanc plugin must expose 4 public functions with the following
+ * signatures:
+ * 
+ * -# <tt>int32_t OrthancPluginInitialize(const OrthancPluginContext* context)</tt>:
+ *    This function is invoked by Orthanc when it loads the plugin on startup.
+ *    The plugin must:
+ *    - Check its compatibility with the Orthanc version using
+ *      ::OrthancPluginCheckVersion().
+ *    - Store the context pointer so that it can use the plugin 
+ *      services of Orthanc.
+ *    - Register all its REST callbacks using ::OrthancPluginRegisterRestCallback().
+ *    - Possibly register its callback for received DICOM instances using ::OrthancPluginRegisterOnStoredInstanceCallback().
+ *    - Possibly register its callback for changes to the DICOM store using ::OrthancPluginRegisterOnChangeCallback().
+ *    - Possibly register a custom storage area using ::OrthancPluginRegisterStorageArea2().
+ *    - Possibly register a custom database back-end area using OrthancPluginRegisterDatabaseBackendV4().
+ *    - Possibly register a handler for C-Find SCP using OrthancPluginRegisterFindCallback().
+ *    - Possibly register a handler for C-Find SCP against DICOM worklists using OrthancPluginRegisterWorklistCallback().
+ *    - Possibly register a handler for C-Move SCP using OrthancPluginRegisterMoveCallback().
+ *    - Possibly register a custom decoder for DICOM images using OrthancPluginRegisterDecodeImageCallback().
+ *    - Possibly register a callback to filter incoming HTTP requests using OrthancPluginRegisterIncomingHttpRequestFilter2().
+ *    - Possibly register a callback to unserialize jobs using OrthancPluginRegisterJobsUnserializer().
+ *    - Possibly register a callback to refresh its metrics using OrthancPluginRegisterRefreshMetricsCallback().
+ *    - Possibly register a callback to answer chunked HTTP transfers using ::OrthancPluginRegisterChunkedRestCallback().
+ *    - Possibly register a callback for Storage Commitment SCP using ::OrthancPluginRegisterStorageCommitmentScpCallback().
+ *    - Possibly register a callback to keep/discard/modify incoming DICOM instances using OrthancPluginRegisterReceivedInstanceCallback().
+ *    - Possibly register a custom transcoder for DICOM images using OrthancPluginRegisterTranscoderCallback().
+ *    - Possibly register a callback to discard instances received through DICOM C-STORE using OrthancPluginRegisterIncomingCStoreInstanceFilter().
+ *    - Possibly register a callback to branch a WebDAV virtual filesystem using OrthancPluginRegisterWebDavCollection().
+ * -# <tt>void OrthancPluginFinalize()</tt>:
+ *    This function is invoked by Orthanc during its shutdown. The plugin
+ *    must free all its memory.
+ * -# <tt>const char* OrthancPluginGetName()</tt>:
+ *    The plugin must return a short string to identify itself.
+ * -# <tt>const char* OrthancPluginGetVersion()</tt>:
+ *    The plugin must return a string containing its version number.
+ *
+ * The name and the version of a plugin is only used to prevent it
+ * from being loaded twice. Note that, in C++, it is mandatory to
+ * declare these functions within an <tt>extern "C"</tt> section.
+ * 
+ * To ensure multi-threading safety, the various REST callbacks are
+ * guaranteed to be executed in mutual exclusion since Orthanc
+ * 0.8.5. If this feature is undesired (notably when developing
+ * high-performance plugins handling simultaneous requests), use
+ * ::OrthancPluginRegisterRestCallbackNoLock().

+   * transfers. The request body is provided as an iterator over data
+   * chunks. The answer is provided as a sequence of function calls
+   * with the individual HTTP headers and answer chunks.
+   * 
+   * Contrarily to OrthancPluginHttpClient() that entirely stores the
+   * request body and the answer body in memory buffers, this function
+   * uses chunked HTTP transfers. This results in a lower memory
+   * consumption. Pay attention to the fact that Orthanc servers with
+   * version <= 1.5.6 do not support chunked transfers: You must use
+   * OrthancPluginHttpClient() if contacting such older servers.
+   *
+   * The HTTP request will be done accordingly to the global
+   * configuration of Orthanc (in particular, the options "HttpProxy",
+   * "HttpTimeout", "HttpsVerifyPeers", "HttpsCACertificates", and
+   * "Pkcs11" will be taken into account).

+   * @param httpStatus The HTTP status after the execution of the request (out argument).
