Release Notes

Version 4.2.2​

Date: 16/12/2025

New Features​

Security and Access Control​

  • PKI Encryption and Signing Support Introduced PKI-based encryption and digital signing for secure message exchange. Includes support for importing key pairs and configuring default keystore settings. This enables enterprise-grade integrity, confidentiality, and simplified key management.

  • Message API Access Control Added configurable authentication for /api/v3/message/queue, /api/v4/message/queue/{name}, and /api/v4/message/queue/bulk/{name}. Enforces user and queue-level validation via a system property (authenticate-queue).

  • Mongo API Access Control Added configurable authentication for the /api/v4/mongo endpoint. Set the authenticate-mongodb property to define how users and API keys are validated when accessing collections.

Low-Code and Workflow Enhancements​

System and UI Improvements​

  • Improved Backup and System Handling Enhanced functionality for automatic and manual snapshots of system state (config, logs, audit, plugins). Supports configurable storage locations, retention limits, and high-performance MongoDB streaming exports.
  • Show Messages Dialog Enhancements The "Show Messages" section now allows for deep inspection, testing, and reprocessing. Messages can be filtered by Plugin or Message Type for easier debugging.
  • Usability Enhancements Application instance names now appear in the browser title, password fields behave consistently, and long text is truncated where needed.

Known Issues​

Groovy option.rest and REST mappings don’t respect truststore certificate chain when a proxy is configured. Workaround: Use option.http

Bug Fixes​

  • Messaging: Fixed retry functionality during the send phase and resolved race conditions/NPEs in memory queues.
  • Security: Sensitive password values are now hidden; 'false' is no longer a valid auth value (defaults to basic).
  • Performance: Optimized audit queries and improved content decompression logic.
  • Reliability: Upgrading plugins no longer overwrites custom settings; ensured queues are declared before publishing on restart.
  • Mapping: Fixed attachment mapping issues and log error message formatting.
  • Metrics: Labeled Prometheus metrics consistently as "1Gateway".

Version 4.2.0​

Date: 30/09/2025

New Features​

  • Configuration-based Workflows (No-Code) Introduces internal plugins (Endpoint, Message Mapper, Switch, Timer, Feedback, etc.) that allow building integrations entirely via configuration. This accelerates development by reducing dependency on custom coding.
  • Enhanced Groovy Capabilities Expanded low-code access to endpoint configurations and variable substitution. Improved logging now includes accurate file/line numbers and better error visibility via the ErrorRegistry.
  • MongoDB API: Introduced advanced filtering capabilities including date-based filtering, sorting, and limiting results.
  • Authentication: Added strict authentication support for bulk operations.
  • Webhook Processing: Added support for configured message types within webhook integrations.
  • Audit Logging: Extended logging capabilities with additional parameters to improve diagnostics and troubleshooting.

Bug Fixes​

  • Improved error handling:
    • Consistency during message processing
    • In regex mappings and auditing.
    • HTTP errors and large JSON responses.
    • In mappers and plugins tatus reporting.
  • General error fixes:
    • Server errors when processing batches with a size of one.
    • Cache was not cleared when importing support files.
    • Poller messages were not displayed correctly.
    • Some audit messages appeared as unavailable in the flow view.
    • UI freezes during periods of high webhook traffic
    • Webhook mappers were not applied correctly.
  • Improved:
    • Handling of different date data types when interacting with MongoDB.
    • Memory usage and thread management under load.
    • Groovy sender performance by avoiding repeated compilation of helper libraries.

Version 4.1.9​

Date: 27/11/2024

New Features​

  • Queue sender plugin Added a queue sender plugin.

  • Queue API availability Introduced a new Queue API to allow programmatic access and management of queues.

  • Improved webhook stability Webhooks now handle missing or empty ID locations more gracefully, preventing runtime errors.

  • Local timezone support in logs Log timestamps can now be configured to use the local timezone via properties configuration, improving log readability and troubleshooting.

Bug Fixes​

  • Mapper segments (“apply another mapper”) no longer create a null top-level branch.
  • key2array no longer adds extra array nesting during array-to-array conversions.
  • Corrected JSON sorting behavior for startTimestamp fields.
  • Fixed webhook handling for bulk message ingestion.
  • Fixed Groovy mapping issue where db.put could create multiple unintended collections.

Known Issues​

  • OAuth authentication via proxy in Groovy mappings OAuth authentication does not function correctly when requests are routed through a proxy in Groovy-based mappings. This issue was fixed in version 4.2.2

    Workaround: Manually perform the OAuth2 token request using the same HTTP client instance that has the proxy explicitly configured.

Custom Groovy OAuth2 Example

// Wait until OAuth2 credentials are available from the endpoint configuration
def oauth2 = null
while (!oauth2) {
    oauth2 = api
        .getAuth(endpoint + "-oauth")
        ?.properties
        ?.authentication

    sleep(10)
}

// Prepare HTTP client
def http = option.http

// Optional: configure proxy if required by your environment
http.useProxy("proxy.example.com")

// OAuth2 token request configuration
http.content("application/x-www-form-urlencoded")

def authUrl = oauth2.token_url

def authBody =
        "grant_type=${oauth2.grant_type}" +
        "&client_id=${URLEncoder.encode(oauth2.client_id, 'UTF-8')}" +
        "&client_secret=${URLEncoder.encode(oauth2.client_secret, 'UTF-8')}" +
        "&username=${URLEncoder.encode(oauth2.user, 'UTF-8')}" +
        "&password=${URLEncoder.encode(oauth2.password, 'UTF-8')}"

// Execute token request
def authResponse = http.post(authUrl, authBody)

// Parse response and extract access token
def authResponseMap = parser.asMap(authResponse)
def accessToken = authResponseMap.access_token

// Optional: log token for debugging (disable in production)
if (log) {
    println(accessToken)
}
