v2.8.0

Release Notes

New Features

1. Implemented DREM optimization for Tensorflow models to OpenVINO:

   • Reduces model load times on cars to 1-2 seconds from 30-45 seconds
   • Equivalent to Optimization Caching (aws-deepracer/aws-deepracer-model-optimizer-pkg#2)
   • Builds on Model Optimizer Lambda Function #9

2. Updated color scheme in the commentator panel to match traditional Motorsports timing colors:

   • Red: Not valid
   • Yellow: Valid
   • Green: Fastest of this race (not racer's personal best)
   • Purple: Fastest of event (so far)

Improvements

1. Added a small CSS patch to cars to prevent UI zoom-in on double-click for touch-screens

2. Tweaked leaderboard text to clarify if Average or Fastest lap is in use

Bug Fixes

1. Fixed deployment issues on x86 machines

v2.7.0

Release Notes

New Features

• Timekeeping Wizard: Introduced a new Timekeeping Wizard that combines the "Upload model to car" functionality with the traditional timekeeper. This simplifies trackside operations by allowing the Time Keeper role to perform both tasks with ease.

• Car Tracking per Lap: Added the ability to track which car was used for each lap. This will enable additional metrics in future releases, such as "Which car was used for the fastest lap?" and "Which car did the most laps?". This feature has also been backported to the original timekeeper.

Improvements

• Streamlined Upload Modals: Updated the existing "Upload model to car" modals to remove an extra container on the status/select modals, reducing on-screen clutter.

New Utilities

• WithEventSelected HOC: Introduced a new reusable Higher-Order Component (HOC) called "WithEventSelected". This HOC can be used to wrap any page that requires an event to be selected, forcing users to select an event before proceeding. This will help simplify the codebase.

v2.6.1

When retrieving lists of users when there are over 5000 users in Cognito, the list users command became unresponsive, to work around this we have added a filter on retrieving users list to only include "Enabled" users from Cognito; this allows a temporary workaround where admins, with access to the AWS Cognito console, can "Disable" users and they will no longer appear in the user list, making the list user command responsive again without any data loss.

Deployments with less than 5000 users need take no action as they will not see this performance issue and the filter added in this release will have no functional impact.

v2.6.0

• New GitHub integrated Pipeline
  • Deployments can now occur directly from GitHub removing the need for an intermediary S3 bucket
• Docker compose
  • A new option has been introduced to simplify local development
  • Containers are now used to host all websites for local development
• Online device links
  • New links to the car console and video feed have been added to the device management for online cars
• Prep for faster model loads
  • This change lays ground work to remove the model loading time on cars by pre-optimising the models with a Lambda function
• various bug fixes
