Aug 31, 2026 Browser SDK 3.23.4 Fixed Restored canvas capture in session recording. With `recordCanvas` enabled and a numeric `sampling.canvas`, snapshots stopped after the first frame and the recording worker reported an uncaught `__awaiter is not defined` error. **[Learn more](https://coralogix.com/docs/user-guides/rum/product-features/session-replay/web.md)** Aug 31, 2026 Browser SDK 3.23.3 Fixed The INP (Interaction to Next Paint) reporter no longer throws an uncaught `TypeError` after a back/forward navigation followed by a tab switch. Aug 20, 2026 Browser SDK 3.23.2 Fixed * `resolved_name` is no longer reported for dead clicks. * Added an optional `fullData` flag to `CoralogixRum.getResolvedName()`, used by Coralogix's own tooling. Aug 19, 2026 Browser SDK 3.23.1 Fixed The public types no longer pull `@types/node` into browser TypeScript builds. Aug 18, 2026 Browser SDK 3.23.0 New [![Product Analytics open to the Heatmaps view, browsing the searchable list of captured pages ranked by session count](/docs/assets/images/product-analytics-overview-ba8ba5c1428b4790dee2e388adf20bba.webp)](https://coralogix.com/docs/assets/images/product-analytics-overview-ba8ba5c1428b4790dee2e388adf20bba.webp) Added support for the Coralogix Product Analytics tool. **[Learn more](https://coralogix.com/docs/user-guides/product-analytics/introduction.md)** Aug 17, 2026 Browser SDK 3.22.1 Fixed * A network request is now reported under the view it started in. A request still in flight when the page changed was previously tagged with the next view's number. * Full page loads now count as view changes in multi-page apps, where `view_number` previously stayed at 0 for the whole session. Requires `sessionConfig.keepSessionAfterReload`. Aug 14, 2026 Browser SDK 3.22.0 Improved * Added support for an explicit ingress URL through the new `coralogixDomainUrl` option, for accounts whose endpoint has no corresponding `coralogixDomain` key. * Initialization now aborts with a clear message when `coralogixDomain` is not a recognized region, instead of sending data to an invalid endpoint. Aug 11, 2026 Browser SDK 3.21.1 Improved Updated the Coralogix domains API URL map. Aug 9, 2026 Browser SDK 3.21.0 Improved [![](/docs/assets/images/3-3-921d94e77c6cf15efe443fb78f83fe85.webp)](https://coralogix.com/docs/assets/images/3-3-921d94e77c6cf15efe443fb78f83fe85.webp) * Upgraded the session recording engine to rrweb 2.1.1. **[Learn more](https://coralogix.com/docs/user-guides/rum/product-features/session-replay/web.md)** * Session recording now keeps working when another library on the page replaces `MutationObserver`. * Style changes are now recorded correctly for CSS rules nested inside `@media` / `@supports`. * Fixed recording errors on browsers without WebGL support. * `url()` references that contain a fragment are now resolved correctly in captured stylesheets.

Jul 6, 2026 Browser SDK 3.16.2 Breaking changeAction required * Fixed PII masking for password input field changes. * **Breaking change:** the default `maskInputTypes` is narrowed from `['password', 'email', 'tel']` to `['password']`, to match the 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. **[Learn more](https://coralogix.com/docs/user-guides/rum/sdk-installation/javascript/browser-sdk/configuration/options.md)** Jun 29, 2026 Browser SDK 3.16.1 Improved Improved user-interaction accuracy: SVG icon clicks are now captured, and role-based and custom controls are resolved.
