Changelog - Coralogix Browser SDK

3.22.0 (2026-08-13)

🚀 Features

• Support an explicit ingress URL via the new coralogixDomainUrl option, for accounts whose endpoint has no corresponding coralogixDomain key

🩹 Fixes

• Abort initialization with a clear message when coralogixDomain is not a recognized region, instead of sending data to an invalid endpoint

3.21.1 (2026-08-11)

🩹 Fixes

• Update CoralogixDomainsApiUrlMap

3.21.0 (2026-08-09)

3.19.2 (2026-07-13)

🩹 Fixes

• fingerprint the clickable ancestor, not the raw click target

3.19.1 (2026-07-12)

🩹 Fixes

• Type sdkFetchPriority with a locally-declared SdkFetchPriority alias instead of the DOM RequestPriority, so the SDK no longer fails to compile on TypeScript versions whose DOM lib predates RequestPriority

3.19.0 (2026-07-12)

🚀 Features

• Add createNewSession() API to manually rotate the session (e.g. on user logout)

3.18.0 (2026-07-08)

🚀 Features

• Add product analytics support for richer product-level insights

3.17.1 (2026-07-07)

🩹 Fixes

🚀 Features

• add configurable OpenTelemetry batch/flush via otelConfig

3.16.2 (2026-07-06)

🩹 Fixes

• Fix PII masking for password input field changes
• The default maskInputTypes is narrowed from ['password', 'email', 'tel'] to ['password'], to match session-recording default. email and tel inputs are no longer masked by default in user-interaction events — set maskInputTypes: ['password', 'email', 'tel'] to restore the previous behavior.

For example:

Before
All Web Vitals instrumentation metrics are enabled by default.

After
To enable the TBT metric, explicitly configure it as shown below:

{
  "instrumentations": {
    "web_vitals": {
      "metrics": {
        "tbt": true
      }
    }
  }

This ensures consistency between page_url_blueprint and page_fragments.

2.10.0 (2025-09-14)
