v7.0.0
This is the v7 major release. It removes deprecated options and legacy code paths accumulated over the v6 line, modernizes the build, and ships a more reliable session manager.
- Smaller, faster bundle — dropping legacy browser shims and switching to ESM dynamic imports reduces the SDK footprint on modern browsers.
- Better privacy out of the box — safer default privacy settings mean less risk of capturing sensitive content without explicit configuration.
- More reliable sessions — modernized session manager with bug fixes, including around very short repetitive sessions.
- Higher-quality data — deterministic sampling (consistent decisions across products), aborted requests no longer polluting error metrics, and a new
session_renewal view loading type to better understand session boundaries.
- A cleaner API — deprecated options and beta flags removed; what's left is the supported, stable surface going forward.
Warning
Upgrading to v7 introduces deterministic sampling for distributed traces based on the RUM session ID. As a result, under RUM without Limits, the likelihood to index sessions that had sampled associated traces is significantly increased — meaning more traces will now be retained by your existing Cross-Product Retention Filters RUMxAPM, even without any configuration change.
If you have cross-product Retention Filters (e.g. RUM-linked APM traces), you may see an increase in the volume of indexed spans, which could lead to higher costs. We recommend reviewing your Retention Filter configuration and estimated span volume after upgrading.
