[!CAUTION] This release is borked, you may read the release notes, but please hold back from upgrading. Users should wait for 26.2.1 for now, or stay in earlier release.

Quick heads-up: If you're wondering where the mid-month release went—we got delayed by a combination of US holidays, Lunar New Year celebrations, and some unexpected hiccups in our new release process built on Craft. It's now fully sorted, and here's what you're getting.

What's New

Data Forwarding is Live

Data forwarding is now available without any feature flags. You'll find it in Organization Settings → Data Forwarding.

This lets you forward processed error events to third-party providers—currently Segment, Amazon SQS, and Splunk. Useful if you're analyzing errors alongside other datasets, empowering teams outside engineering, or building business intelligence workflows. Note that only error events are forwarded; spans and logs aren't supported yet.

Important Fixes

Missing Feature Flag for Metrics Alerts

If metrics alerts haven't been working for you, check that your sentry.conf.py includes the necessary feature flags from sentry.conf.example.py. Specifically, compare the feature flags section and add anything that's missing.

Nodestore S3 Writes Fixed

We noticed a bug regarding Nodestore writes that was caused by an unbounded boto3 dependency. Fixed in getsentry/sentry-nodestore-s3#3. If you're using S3 for Nodestore, this update should resolve any intermittent write failures you may have seen.

Maintenance

Nginx and Seaweedfs Bumps

We've updated both Nginx and Seaweedfs to their latest versions. These are minor version bumps with no breaking changes, but because the image tags changed, you'll end up with orphaned images. Run docker image prune --all after updating to clear out the old ones and reclaim disk space.

As always, if you run into any issues or have questions about your setup, hop into our Discord—we're always happy to help troubleshoot.
