What's new

• The Server Properties and Update Server Properties endpoints have been updated to support a new property, diskSpaceThresholdGB. The diskSpaceThresholdGB property specifies the threshold of usable disk space.

• The Import Existing Server Certificate operation has been updated to include the importCertificateChain parameter. The importCertificateChain parameter specifies if the operation should also import the root or intermediate certificates included inside the certificate file.

• A new event trigger, FeaturesPosted, has been added for feature service webooks. The Create or Edit operations can be used to include this event trigger for feature service webhooks.

• The Import Site operation has been updated to support a new parameter, restartWebServer. This parameter specifies whether the server should restart once the operation completes.

No endpoints were deprecated at this release.

Service webhooks have been updated to use signature verification to ensure the integrity and security of webhook payloads sent from ArcGIS Enterprise to a webhook receiver. Service webhooks can now be created or updated to use this new security measure.

No endpoints were deprecated at this release.

• Two new properties, validFromEpoch and validUntilEpoch, have been added to the response of the SSL Certificate resource. The validFromEpoch property shows the date and time information (in Unix epoch format) for when a certificate's validity begins, and the validUntilEpoch property shows the date and time information (in Unix epoch format) for when a certificate's validity ends.
• The Export Site operation supports the validate parameter. The validate parameter ensures that the folder path where the exported content will be written is accessible to ArcGIS Server before performing the operation.
• The Import Site operation supports the validate parameter. The validate parameter ensures that the folder path where the exported site configuration is located is accessible to ArcGIS Server before performing the operation.

No endpoints were deprecated at this release.

• The Edit Services Directory operation supports a new parameter, callbackFunctionsEnabled. This parameter sets the flag to enable or disable the ability to make JSONP callback requests.
• The Upgrade operation supports a new parameter, enableDebug. This parameter sets the log level for the upgrade process.

At this release, ArcGIS Server no longer supports the ArcMap runtime or publishing services from ArcMap. After upgrading to ArcGIS Enterprise 11.0 or later, any remaining geocode or geoprocessing services that were originally published from ArcMap cannot be started and must be republished from ArcGIS Enterprise. Starting from ArcGIS Enterprise 11.0, services must be created using the ArcGIS Pro service runtime and the ArcObjects11 provider.

• The new security configuration property, allowInternetCORSAccess, controls the value of the "Access-Control-Allow-Private-Network" response header in a CORS preflight request to a REST service URL.
• Two new system properties have been added: maxHttpPostSizeInBytes and webServerMaxRequestThreads. The maxHttpPostSizeInBytes property allows users to change the maximum size in bytes for POST requests sent to ArcGIS Server. The webServerMaxRequestThreads property allows users to change the maximum number of threads that are available at one time to process requests sent to ArcGIS Server.

The Python Software Foundation has ended support for the Python 2 programming language, impacting the ArcMap service runtime that uses Python 2.x. At 10.9.1, when installing ArcGIS Server, you will have the option to disable the ArcMap service runtime, removing Python 2.x from your deployment. Disabling the ArcMap runtime will impact the following operations and resources in the ArcGIS Server Admin API:

• Start Service—If the ArcMap runtime is disabled, services with ArcMap (ArcObjects) as their service provider will be stopped. Attempting to start these services will result in an error.
• Create Service—Creating a service with ArcMap (ArcObjects) as the service provider when the ArcMap runtime is disabled will result in an error.
• Register Extension—Registering ArcMap-based SOE items to your organization when the ArcMap runtime is disabled will result in an error.
• Join Site—ArcGIS Server sites will be able to successfully run the joinSite operation if the joining machine has a matching status for the ArcMap runtime to that of the existing server site. If the joining machine has a conflicting ArcMap runtime status, attempting the joinSite operation will result in an error message.
• Register Machine—If the server machine being registered with the ArcGIS Server site has a conflicting ArcMap runtime status, attempting to register the machine will result in an error message.
• Providers—This resource now returns a list of enabled providers, indicating whether both the ArcMap (ArcObjects) and ArcGIS Pro (ArcObjects11) runtimes are enabled, or only the ArcGIS Pro runtime is enabled.
• Change Provider—This operation now supports changing the provider type of ArcMap services (ArcObjects) to ArcGIS Pro (ArcObjects11), migrating these services from the ArcMap service runtime to the ArcGIS Pro service runtime.

The Server Properties, uploadFileExtensionWhiteList and uploadItemInfoFileExtensionWhitelist, have been updated to uploadFileExtensionAllowedList and uploadItemInfoFileExtensionAllowedList, respectively.

Starting with Insights 2021.1, the registration and management of relational data store types should be performed with ArcGIS Insights. For more information, see Manage connector types.

• The Register Relational Data Store Type operation was introduced at 10.5 and allowed the user to register a new relational data store type with the server.
• The Edit Relational Data Store Type operation was introduced at 10.5 and allowed the user to edit a registered relational data store type to update its properties.
• The Relational Data Store Type resource was introduced at 10.5 and returned a list of the properties for a registered relational data store type.
• The Relational Data Store Types resource was introduced at 10.5 and returned a list of the relational data store types that were registered with the server.
• The Unregister Relational Data Store Types operation was introduced at 10.5 and allowed the user to unregister a relational data store type from the server.

Edit Service now supports the ability to specify if a service's virtual directories are secured and require authentication. This is associated with the site-wide property that can be set through the Update Security Configuration operation.

Privilege-based access

Access to the Server Admin API is based off the privileges included in either a user's custom or default role, enabling administrators to restrict or grant access to the resources and operations that are associated with, and required by, their assigned privileges. At 10.8, this functionality was first introduced through changes made to administrator access to the Portal Admin API directory. At 10.8.1, this same privilege-based system has been implemented for the ArcGIS Server Admin API directory.

No endpoints were deprecated at this release.

• Compatible map services published from ArcGIS Pro to ArcGIS Server will initially use the shared instance pool by default. The default instance type can be changed either through the Server Manager or the Update Default Service Properties operation. As well, the instance type of an individual and compatible map service can be changed through the Change Provider operation.
• The Update Site Mode operation has a new parameter, allowEditingViaServices, that specifies if edits for feature services are allowed while the site is in read-only mode.

No endpoints were deprecated at this release.

The featureServiceXSSFilter server property is used to set the value of the xssPreventionRule for feature services when they are published by either applying an XSS filter to any attribute data input into a feature service for new or updated features, or filtering the input data and output data for XSS strings.
