Release v1.0.6

Features:

• Add Android support, including shared library and demonstration app.

Improvements:

• Change from arn to sync_id for campaign_arn and document_arns, the sync_id being the ARN
  followed by the timestamp of the last update. The change is backwards compatible with older
  versions of the edge agent.
• Ubuntu package mirror from system used, rather than ports.ubuntu.com.
• Add root CA and inline credentials support to static config file.
• Add extra metrics for AWS SDK heap usage, used signal buffer, MQTT messages sent out.
• Add support for in-process ingestion of external GPS, CAN and OBD PID values when FWE is compiled
  as a shared library.
• Fix compiler warnings for armhf build.
• Update Protobuf to v3.21.12, AWS C++ SDK to v1.11.94.

Release v1.0.5

Bugfixes:

• RemoteProfiler not always uploading logs

Improvements:

• Refactor Producer/Consumer architecture, removing the buffer and thread between the
  CANDataSource and the CANDataConsumer. The static config option socketCANBufferSize was
  therefore removed.
• Add documentation on how to use edge specific metrics.
• Change from arn to sync_id for all decoder manifest Protobuf fields, the sync_id being the
  ARN followed by the timestamp of the last update. The change is backwards compatible with older
  versions of the edge agent.
• Improve MISRA C++ 2008, and AUTOSAR C++ compliance.
• Updated CloudFormation templates to use IMDSv2.

Release v1.0.4

Bugfixes:

• Fix OBD timers not being reset. If the decoder manifest is empty or DTCs are not collected the OBD
  PID or DTC timers were not reset, causing a 100% CPU and log spam with the following message
  [WARN ] [OBDOverCANModule::doWork]: [Request time overdue by -X ms].
• Support OBD2 PIDs ECU response in different order than requested. Also accept ECU response if not
  all requested PIDs are answered.
• Unsubscribe and disconnect from MQTT on shutdown: previously a message arriving during shutdown
  could cause a segmentation fault.

Improvements:

• Update to Ubuntu 20.04 for the development environment.
• Add flake8 checking of Python scripts.
• Improve GitHub CI caching.
• Improve MISRA C++ 2008, and AUTOSAR C++ compliance.
• Improve logging: macros used to automatically add file, line number and function.
• Improve unit test stability, by replacing sleep statements with 'wait until' loops.
• Removed redundant JSON output code from DataCollection* files.

Work in Progress:

• Support for signal datatypes other than double, including uint64_t and int64_t.

Release v1.0.3

Features:

• Added OBD broadcast support to send functional rather than physical requests to ECUs to improve compatibility with a broader range of vehicles.
  This behavior does however increase CAN bus load. The config option broadcastRequests can be set to false to disable it.

Bugfixes:

• Fix CollectionSchemeManager and CollectionInspectionEngine to use monotonic clock
  This now makes check-in and data collection work even when the system time jumps.
  Please note that the timestamp present in check-in and collected data may still represent the system time, which means that newly collected data may
  be sent with a timestamp that is earlier than the previous sent data in case the system time is changed to some time in the past.

Improvements:

• Logs now show time in ISO 8601 format and UTC.
• Added optional config logColor for controlling ANSI colors in the logs. Valid values: Auto, Yes, No. Default value is Auto, which will make
  the agent try to detect whether stdout can interpret the ANSI color escape sequences.
• A containerized version of the edge agent is available from AWS ECR Public Gallery: https://gallery.ecr.aws/aws-iot-fleetwise-edge/aws-iot-fleetwise-edge.
• Improve CERT-CPP compliance.
• Improve quick start guide and demo script.
• Clarify the meaning of the startBit.

Release v1.0.2

Bugfixes:

• Fix Timer to use a monotonic clock instead of system time. This ensures the Timer will correctly measure the elapsed time when the system time changes.
• Use std::condition_variable::wait_until instead of wait_for to avoid the bug when wait_for uses system time.
• Fix extended id not working with cloud.
• Handle SIGTERM signal. Now when stopping the agent with systemctl or kill without additional args, it should gracefully shutdown.
• Fix bug in canigen.py when signal offset is greater than zero.

Improvements:

• Pass signalIDsToCollect to CANDecoder by reference. This was causing unnecessary allocations/deallocations, impacting the performance on high load.
• Add binary distribution of executables and container images built using GitHub actions.
• Add support for DBC files with the same signal name in different CAN messages to cloud demo script.
• Improve CERT-CPP compliance.

Release v1.0.1

v1.0.1 (Nov 3, 2022)

License Update:

• License changed from Amazon Software License 1.0 to Apache License Version 2.0

Security Updates:

• Update protcol buffer version used in customer build script to v3.21.7

Features:

• OBD module will automatic detect ECUs for both 11-bit and 29-bit. ECU address is no longer hardcoded.
• Support CAN-FD frames with up to 64 bytes
• Add an CustomDataSource for the IWave GPS module (NMEA output)
• iWave G26 TCU tutorial
• Renesas R-Car S4 setup guide

Bugfixes:

• Fix name of persistencyUploadRetryIntervalMs config. The dev guide wasn't including the Ms suffix and the code was mistakenly capitalizing the first letter.
• Don't use SocketCAN hardware timestamp as default but software timestamp. Hardware timestamp not being a unix epoch timestamp leads to problems.
• install-socketcan.sh checks now if can-isotp is already loaded.
• The not equal operator =! in expression is now working as expected
• Fix kernel timestamps in 32-bit systems

Improvements:

• Added Mac-user-friendly commands in quick demo
• Added an extra attribute, so that users can search vehicle in the FleetWise console
• Added two extra steps for quick demo: suspending campaigns and resuming campaigns

Release v1.0.0

v1.0.0 (Sept 27, 2022)

Bugfixes:

• Fixed an OBD bug in which software requests more than six PID ranges in one message. The new revision request the extra range in a separate message.
• Fixed a bug in CANDataSource in which software didn't handle CAN message with extended ID correctly.

Improvements:

• Remove the html version of developer guide.
• Remove source code in S3 bucket. The S3 bucket will only be used to host quick demo cloud formation.
• Remove convertToPeculiarFloat function from DataCollectionProtoWriter.
• Set default checkin period to 2-min in static-config.json. The quick demo will still use 5 second as checkin period.
• Update FleetWise CLI Model to GA release version.
• Update Customer Demo to remove service-linked role creation for FleetWise Account Registration.

Release v0.1.4

Bugfixes:

• Fixed a bug in which software will continue requesting OBD-II PIDs or decoding CAN messages after all collection schemes removed.

Improvements:

• OBDOverCANModule will only request PIDs that are to be collected by Decoder Dictionary and supported by ECUs.
• OBDDataDecoder will validate the OBD PID response Length before decoding. If software detect response length mismatch with OBD Decoder Manifest, program will do 1) Log warning; 2) Discard the entire response.
• OBDDataDecoder will only decode the payload with the PIDs that previously requested.
• Improve OBD logging to log CAN ISOTP raw bytes for better debugging

Release v0.1.3

Customer Demo:

• Updated demo scripts to match with latest AWS IoT FleetWise Cloud API changes
• Fix a bug in demo script that might render scatter plot incorrectly.

Docs:

• Updated the Edge Agent Developer Guide to match with latest AWS IoT FleetWise Cloud API changes
• Updated Security Best Practices in Edge Agent Developer Guide

Bugfixes:

• Fixed a bug which previously prevented OBD from functioning at 29-bit mode.
• Fixed a bug that potentially caused a crash when two collection schemes were using the same
  Signal Ids in the condition with different minimum sampling intervals

Improvements:

• Signal Ids sent over Protobuf from the cloud can now be spread across the whole 32 bit range,
  not only 0-50.000
• Security improvement to pass certificate and private key by content rather than by file path
• Improvement to Google test CMake configuration
• Clang tidy coverage improvements
• Improvement to AWS SDK memory allocation with change to custom thread-safe allocator
• Re-organized code to remove cycles among CMake library targets
• Refactored Vehicle Network module to improve extensibility for other network types
