Feature Added

• Add Clock/ROSClock class support.
• Add TimeSource class support, which enables you to attach Clocks to it and update them by receiving the topic of builtin_interfaces/msg/Time.

Improvements

• As the maximum safe integer in JavaScript is (2^53 - 1) due to double-precision floating-point format numbers specified in IEEE_754, the int64_t cannot be represented in JavaScript. We are going to use the string format of the integer for Time and Duration when exceeding the limitation, e.g.

let time = new Time(0, '9007199254740992'); // time.nanoseconds equals  '9007199254740992'

let duration = new Duration(0, '9007199254740992'); // duration.nanoseconds equals  '9007199254740992'

Release Note

• This patch release fixed a problem which caused by the new error handling API #429

Release Note

New Features

• time feature (#424)
• duration feature (#425)

Release Note

New Features

• Actions (experimental)
  The actionlib stack provides a standardized interface for interfacing with preemptable tasks, by leveraging the actionlib_nodejs module, we implemented it as an experimental feature in this release. You can simply define a .action file

# Define the goal
uint32 dishwasher_id  # Specify which dishwasher we want to use
---
# Define the result
uint32 total_dishes_cleaned
---
# Define a feedback message
float32 percent_complete
# Use a message from another package, to prove that it works
sensor_msgs/Image image

create a client

  const ac = new rclnodejs.ActionClientInterface({
    type: 'ros1_actions/msg/DoDishes',
    actionServer: 'dishes',
    rclnodejs: rclnodejs
  });

create a server

  const as = new rclnodejs.ActionLib.ActionServer({
    type: 'ros1_actions/msg/DoDishes',
    actionServer: 'dishes',
    rclnodejs: rclnodejs
  });

Also, you could reference the tutorial for detailed usage.
