We're preparing our next major on this branch.

The project is tracked in Linear. If you don't have access, we'll try to tag issues belonging to the project with the SDK 3.0 label on GitHub so that you can follow along.

Context

You might have read this announcement about us discontinuing work on a 3.0. This is referring to the work done on the potel-base branch, which included two types of changes: a huge refactor of our tracing code on the one hand, and various unrelated changes, improvements and fixes on the other. We're dropping the huge refactor part, and only porting the rest, to a new branch and eventually a new 3.0 release.

Comment thread sentry_sdk/consts.py
sentrivana and others added 4 commits July 28, 2026 11:47
Add `UnraisablehookIntegration` to the default integrations list.
Stop raising exceptions `from None` in the ASGI and asyncio integrations.

Closes #5624
Remove everything hub related, including all sorts of compatibility
shims around hubs/scopes.

Also remove deprecated session methods.

`configure_scope` and `push_scope` removal coming in a future PR.

#### Issues
Closes #5001
The integration requires additional configuration which should be
intentional on the user's part.

#### Issues
Closes #4993
- Remove everything in `integrations/opentelemetry`
(`SentrySpanProcessor`, `SentryPropagator`, etc.)
- Remove associated test files and CI config
- Move old propagator functions and consts that we were using in
`OTLPIntegration` to the OTLP propagator directly
- Remove `instrumenter`

Note: `NoOpSpan` was not removed because it makes mypy blow up. Not
worth the effort as we'll anyway get rid of it when dropping transaction
based tracing.

#### Issues
Closes #6932
Comment thread sentry_sdk/integrations/otlp.py
### Description
The API is deprecated and slated for removal in 3.0.

#### Issues
Closes #5019

### Description
Remove the deprecated API.

#### Issues
Closes #5018
…new major (#6948)

### Description
When `failed_request_status_codes` was first introduced, it accepted a
different format. The format was then changed, while the old format was
deprecated. Drop support for the old format now.

#### Issues
Closes #5017
