New Features Introduced in Release 10.15.0 and Earlier Releases

This section lists the new features introduced in the Solace PubSub+ Messaging API for JavaScript between releases 10.15.0 and 10.7.0.
NameDescriptionIntroduced in Version
JavaScript API - Provide Ability to NACK a Specific AD Message and Force Redelivery
The Messaging API for JavaScript now supports message NACK.

Enables adding and extracting tracing metadata attached to events published and received by the Solace JavaScript API.

JavaScript API - Support for Partitioned Queues
This enhancement adds support for Partitioned Queues to the API. Partitioned Queues expand PubSub+ to provide deterministic, ordered, and non-exclusive message delivery for customers to scale the number of consumers when publishing ordered datasets. The ordered datasets are keyed to ensure all events in the dataset are sent to the same consumer without mis-ordering events.
10.13.0
Prevent Republishing of Guaranteed Messages that Exceed the Maximum Message Size
This feature prevents applications from sending guaranteed messages that exceed the maximum message size configured in the PubSub+ Event Broker to prevent erroneous states in the API.

Javascript - Add Way to Update OAuth Token on Reconnection
This feature allows an application to automatically update the OAuth token without the need to create a new session the next time the API tries to reconnect.
10.10.0
Create a TypeScript Type Definition for the JavaScript API
The TypeScript Definition file for the Javascript API provides TypeScript type information, which enables developers to make use of the Javascript API in their TypeScript projects.
10.9.0
Improve Logging in the SolClient-Full Library
Moved many connection-related and state-affecting logging messages from DEBUG to INFO, in keeping with industry practices.
10.9.0
OAuth/OIDC Support in Messaging API for JavaScript
OAuth / OpenID Connect has been added as a method of authenticating and authorizing clients connecting to the PubSub+ Event Broker using the SMF protocol.

10.9.0
Solace PubSub+ Messaging API for JavaScript - Configure Topic-to-Queue Mappings
The Solace PubSub+ Messaging API for JavaScript now supports adding and removing subscriptions from endpoints that support them (topic-to-queue mapping).

The "ws" module that is used by the Solace JavaScript API can be flagged as vulnerable to CVE-2021-32640 during security scans that only check the version number of modules.
Note that the Solace JavaScript API is not actually vulnerable to the CVE because the JavaScript API only acts as a WebSocket client and not a server.
This fix updates the version of the "ws" module to prevent these scanners from flagging the API.
