26.2.0

> [!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](https://github.com/getsentry/craft). It's now fully sorted, and here's what you're getting. ## What's New **Data Forwarding is Live** [Data forwarding](https://docs.sentry.io/organization/integrations/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](https://github.com/getsentry/sentry-nodestore-s3/pull/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](https://discord.gg/sentry)—we're always happy to help troubleshoot. ## New Features ✨ * Updates seaweedfs image to 4.09 by @ronaldorcampos in https://github.com/getsentry/self-hosted/pull/4173 * Provide blank environment variables for AWS SES relay by @aldy505 in https://github.com/getsentry/self-hosted/pull/4164 ## Bug Fixes 🐛 * (test) Add Authority Key Identifier to SSL certificates by @oioki in https://github.com/getsentry/self-hosted/pull/4162 * Add "organizations:on-demand-metrics-extraction" ff to enable metric alerts by @mzglinski in https://github.com/getsentry/self-hosted/pull/4170 ## Internal Changes 🔧 ### Deps - Bump getsentry/craft from 2.21.2 to 2.21.4 by @dependabot in https://github.com/getsentry/self-hosted/pull/4172 - Bump getsentry/craft from 2.20.1 to 2.21.2 by @dependabot in https://github.com/getsentry/self-hosted/pull/4166 - Bump getsentry/action-release from 3.4.0 to 3.5.0 by @dependabot in https://github.com/getsentry/self-hosted/pull/4133 - Bump actions/checkout from 6.0.0 to 6.0.2 by @dependabot in https://github.com/getsentry/self-hosted/pull/4155 - Bump actions/setup-python from 6.1.0 to 6.2.0 by @dependabot in https://github.com/getsentry/self-hosted/pull/4154 - Bump getsentry/craft from 2.19.0 to 2.20.1 by @dependabot in https://github.com/getsentry/self-hosted/pull/4152 - Bump actions/setup-node from 6.1.0 to 6.2.0 by @dependabot in https://github.com/getsentry/self-hosted/pull/4153 - Bump astral-sh/setup-uv from 7.1.6 to 7.2.0 by @dependabot in https://github.com/getsentry/self-hosted/pull/4132 - Bump codecov/test-results-action from 1.1.1 to 1.2.1 by @dependabot in https://github.com/getsentry/self-hosted/pull/4115 - Bump codecov/codecov-action from 5.5.1 to 5.5.2 by @dependabot in https://github.com/getsentry/self-hosted/pull/4102 - Bump urllib3 from 2.5.0 to 2.6.3 by @dependabot in https://github.com/getsentry/self-hosted/pull/4150 ### Other - (craft) Update minVersion from 0.23.1 to 2.21.6 by @BYK in https://github.com/getsentry/self-hosted/pull/4177 - (deps-dev) Bump cryptography from 46.0.3 to 46.0.5 by @dependabot in https://github.com/getsentry/self-hosted/pull/4168 - Fix changelog-preview for external contributors by @BYK in https://github.com/getsentry/self-hosted/pull/4158 ## Other - Bump nginx 1.29.5 by @aminvakil in https://github.com/getsentry/self-hosted/pull/4167 - Allow configuring Sentry taskworker concurrency via env by @madest92 in https://github.com/getsentry/self-hosted/pull/4149
