# Major Release History

## Release 11.0.0
  * Highlights
    * Authenticated UDS connections support: USP Services must provide a passsword if connecting via an authenticated UDS socket
    * Data model registration permissions support: The USP Broker can control which DM elements a USP Service is allowed to register
    * Support for permission Targets containing search expressions
    * Experimental file descriptor passing via Unix domain socket ancilliary data for USP Services. To enable, define FD_PASSING_EXPERIMENTAL in vendor_defs.h
    * Device.LocalAgent.AddCertificate() support. See QUICK_START_GUIDE.md for how to use this feature
    * TP-469 Conformance Test Plan Results for each release are now checked into the repo, in the file conformance_test_results.txt
    * 'obuspa -c add' CLI command now supports setting child parameters
    * Functions to access the data model from vendor threads (USP_PROCESS_DoWorkSync, USP_PROCESS_DM_GetParameterValue, USP_PROCESS_DM_SetParameterValue)
    * If USP database file is corrupt, a new database is created using the factory reset configuration
    * Maximum allowed MTP frame size received has been increased to 5MB (from 64K)

    * Fixed crash if USP Service registers a DM element, but does not provide it in the GSDM response
    * Fixed race hazard causing USP Broker to reject all messages from a USP Service. Occurs when USP Service disconnects, then immediately reconnects over UDS MTP, whilst USP Broker is waiting for a synchronous USP response
    * USP Command and Event arguments should not be allowed to be registered more than once
    * USP Services should not reuse group_ids registered by internal data model providers
    * Prevented assert when changing LocalAgent.MTP.Enable and Protocol is UDS

    * MQTT client should not disconnect if no Response Topic
    * MQTT connection should be retried if TLS handshake fails and libmoquitto version<2.0.13
    * MQTT Send message queue should not get stuck if packet too large

    * Configure options to enable address sanitizer (--enable-asan) and thread sanitizer builds (--enable-tsan) have been added. These options are disabled by default.
    * Configure option (--enable-hardening) to enable compiler hardening flags (disabled by default)
    * To support compilation of OBUSPA data model plug-ins, the build process now installs header files to $(includedir)/obuspa

  * USP API
    * Added USP_LOG_GetLogLevel and USP_LOG_SetLogLevel API functions to atomically access the log level at runtime
    * Added USP_SIGNAL_Reboot API function to initiate shutting down, then rebooting the device

    * Fixed regression (introduced in v10.0.0) with Async Operation max concurrency limit
    * ControllerTrust Permission Order uniqueness is now enforced when Add request with allow_partial=false adds multiple permissions with the same Order
    * GSDM response does not contain unique keys for child objects when first_level_only=true
    * Prevented first object creation notification after bootup being missed
    * OBUSPA now returns correct error code to pass conformance test 1.100
    * Alias uniqueness validation failures now return error code 7004 instead of 7025.

    * GSDM response can return the sets of unique keys for each multi-instance object
    * Reason and Cause arguments have been added to Device.Reboot(), Device.FactoryReset() and Device.Boot!

    * Optimized requests and subscriptions containing search expressions
    * Event and OperationComplete subscriptions to 'Device.' have been modified so that they set subscriptions on each USP Service containing only the DM elements that were registered

      (`obuspa -c service [endpoint] [command] [path-expr] [optional: value or notify type]`)

    * OBUSPA should delete pending USP notifications (on MQTT MTP) if notification has expired whilst waiting to be sent
    * MQTT connection blocks for too long if server is unresponsive. To workaround the underlying issue in libmosquitto, OBUSPA tests for server responsiveness by transiently connecting, before proceeding with the libmosquitto connect (if responsive).
    * OBUSPA should disconnect if unable to subscribe to anything [R-MQTT.17]
    * Device.MQTT.Client.{i}.Name should be auto-assigned by the agent, if not given at creation time, and immutable thereafter
    * Device.MQTT.Client.{i}.RequestResponseInfo should control whether response information is requested in the CONNECT frame. Previously it was always requested, regardless of the value of the parameter
    * Removed unimplemented parameter: Device.MQTT.Client.{i}.RequestProblemInfo
    * Modifying MQTT KeepAliveTime should not force a reconnect
    * MQTT ConnectRetryTime parameter modifications should apply at the next retry [GH #109]

  * STOMP
    * STOMP connects shouldn't block the data model thread
    * STOMP ServerRetryMaxInterval parameter modifications should apply at the next retry

    * Workaround for USP Services which have limitations on the number of parameters requested in a get
    * Support additional DM elements registered directly under Device.
    * USP Broker should not assume hierarchically ordered fields in GSDM and get instances responses
    * USP Service acting as pure Controller does not accept responses unless Broker is in the USP Service's Controller table

  * Data model
    * VALUE_CHANGE_WILL_IGNORE flag support
    * Get requests with max_depth >= 0x80000000 should return full sub-tree
    * Get instances failures during path resolution should be gracefully ignored

  * WebSockets MTP
    * EndpointID is now indicated in the query component of the WebSocket request URI [R-WS.10b]
    * When using WebSockets MTP, the ping failure count was not being reset after reconnect. Under certain circumstances this led to unnecessary reconnects.
  * Integrator enhancements
    * New vendor hooks
      * can_mtp_connect_cb - allows the vendor layer to delay connection to a Controller ACS until critical device functionality is running (for example NTP time synchronized)
      * modify_firmware_updated_cb - allows the vendor layer to modify the FirmwareUpdated argument being passed in the Boot! event. This can be used to override the default calculation for this argument, if it does not catch all cases of the firmware being updated.
    * New USP API functions
      * USP_PROCESS_DoWork - allows the vendor layer to perform work in the context of the data model thread (for example calling USP_DM_SetParameterValue)
      * USP_REGISTER_AsyncOperation_MaxConcurrency - used to prevent concurrent processing of duplicate asynchronous USP commands


  * Bug Fixes
    * The default value for Device.LocalAgent.MTP.{i}.Protocol has been made dependent on which MTPs are configured in the build options

    * Under certain circumstances, object creation notifications could have been sent at start up before the Boot! notification
    * A cause of error due to changes in the instantiated data model during the processing of USP requests has been prevented
    * Non UTF-8 characters in JSON formatted text containing parameter values are now converted to the Unicode replacement character (U+FFFD)
    * A subscription's ReferenceList is now immutable after being set

## Release 7.0.0

  * Bug Fixes
    * MQTT MTP
      * GH#30: MQTT publish QoS cannot be configured (stuck at 0)
      * For MQTTv3.x MTP, Agent should subscribe to wildcarded agent topic and publish to topic containing '/reply-to='
      * When changing a subscription's topic, The agent was unsubscribing from the new topic (not the old topic)
      * For MQTTv5 MTP, Agent should subscribe to topic from CONNACK, if available

      * USP Record should be ignored if the protobuf cannot be unpacked

    * Miscellaneous
      * GH#55: Updated Dockerfile to use Ubuntu Kinetic which includes the required versions of libmosquitto and libwebsockets
      * GH#64: Crash if PeriodicNotifInterval is set to 0
      * GetResponse optimized for large numbers of object instances
      * If 'obuspa -c get' truncates the printing of a parameter value, this is now indicated
      * OnBoardRequest notification should be retried, if corresponding NotifyResponse not received
      * Adding a Controller MTP object fails, if Protocol is not specified and CoAP is disabled ('configure --disable-coap')
      * Default value for RebootCause would be better as "FactoryReset"
      * Alias should be registered as a unique key for LocalAgent.Certificate
      * GetSupportedDM response should indicate that parameters registered with USP_REGISTER_DBParam_SecureWithType() are readable
      * Added note that the start_transaction vendor hook must never return a failure, as it is not possible for OBUSPA to handle the failure in all cases
