Changelog and versioning

Versioning Policy

This project follows semver, with three additions:

Semver says that major version 0 can include breaking changes at any time. Still, it is common practice to assume that only 0.x releases (minor versions) can contain breaking changes while 0.x.y releases (patch versions) are used for backwards-compatible changes (bugfixes and features). This project also follows that practice.
All undocumented APIs are considered internal. They are not part of this contract.
Certain features (e.g. integrations) may be explicitly called out as "experimental" or "unstable" in the documentation. They come with their own versioning policy described in the documentation.

We recommend to pin your version requirements against 1.x.* or 1.x.y. Either one of the following is fine:

sentry-sdk>=0.10.0,<0.11.0
sentry-sdk==0.10.1

A major release N implies the previous release N-1 will no longer receive updates. We generally do not backport bugfixes to older versions unless they are security relevant. However, feel free to ask for backports of specific commits on the bugtracker.

Fix a bug that caused Django apps to crash if the view didn't have a __name__ attribute.

0.16.4

Add experiment to avoid trunchating span descriptions. Initialize with init(_experiments={"smart_transaction_trimming": True}).

Breaking change: before_send is no longer called for transactions.

0.15.1

Fix fatal crash in Pyramid integration on 404.

0.15.0

Breaking change: The ASGI middleware will now raise an exception if contextvars are not available, like it is already the case for other asyncio integrations.
Contextvars are now used in more circumstances following a bugfix release of gevent. This will fix a few instances of wrong request data being attached to events while using an asyncio-based web framework.

Fix a bug in the Pyramid integration where the transaction name could not be overridden at all.
Fix a broken type annotation on capture_exception.
Basic support for Django 3.1. More work is required for async middlewares to be instrumented properly for APM.

0.13.5

Fix trace continuation bugs in APM.
No longer report asyncio.CancelledError as part of AIOHTTP integration.

Fix a bug where None inside request data was skipped/omitted.

0.13.3

Fix an issue with the ASGI middleware that would cause Uvicorn to infer the wrong ASGI versions and call the wrapped application with the wrong argument count.
Do not ignore the tornado.application logger.
The Redis integration now instruments Redis blaster for breadcrumbs and transaction spans.

0.13.2

Fix a bug in APM that would cause wrong durations to be displayed on non-UTC servers.

0.13.1

Add new global functions for setting scope/context data.
Fix a bug that would make Django 1.11+ apps crash when using function-based middleware.

0.13.0

Remove an old deprecation warning (behavior itself already changed since a long time).
The AIOHTTP integration now attaches the request body to crash reports. Thanks to Vitali Rebkavets!
Add an experimental PySpark integration.
First release to be tested under Python 3.8. No code changes were necessary though, so previous releases also might have worked.

0.12.3

Various performance improvements to event sending.
Avoid crashes when scope or hub is racy.
Revert a change that broke applications using gevent and channels (in the same virtualenv, but different processes).
Fix a bug that made the SDK crash on unicode in SQL.

0.12.2

Fix a crash with ASGI (Django Channels) when the ASGI request type is neither HTTP nor Websockets.

0.12.1

Temporarily remove sending of SQL parameters (as part of breadcrumbs or spans for APM) to Sentry to avoid memory consumption issues.

0.12.0

Sentry now has a Discord server! Join the server to get involved into SDK development and ask questions.
Fix a bug where the response object for httplib (or requests) was held onto for an unnecessarily long amount of time.
APM: Add spans for more methods on subprocess.Popen objects.
APM: Add spans for Django middlewares.
APM: Add spans for ASGI requests.
Automatically inject the ASGI middleware for Django Channels 2.0. This will break your Channels 2.0 application if it is running on Python 3.5 or 3.6 (while previously it would "only" leak a lot of memory for each ASGI request). Install aiocontextvars from PyPI to make it work again.

0.11.2

Fix a bug where the SDK would throw an exception on shutdown when running under eventlet.
Add missing data to Redis breadcrumbs.

0.11.1

Remove a faulty assertion (observed in environment with Django Channels and ASGI).

0.11.0

Fix type hints for the logging integration. Thanks Steven Dignam!

Fix a series of bugs in the stdlib integration that broke usage of subprocess.
More instrumentation for APM.

0.10.2

Fix a bug where a log record with non-strings as extra keys would make the SDK crash.
Added ASGI integration for better hub propagation, request data for your events and capturing uncaught exceptions. Using this middleware explicitly in your code will also fix a few issues with Django Channels.
Fix a bug where celery-once was deadlocking when used in combination with the celery integration.
Fix a memory leak in the new tracing feature when it is not enabled.

0.10.1

Fix bug where the SDK would yield a deprecation warning about collections.abc vs collections.
Fix bug in stdlib integration that would cause spawned subprocesses to not inherit the environment variables from the parent process.

0.10.0

Massive refactor in preparation to tracing. There are no intentional breaking changes, but there is a risk of breakage (hence the minor version bump). Two new client options traces_sample_rate and traceparent_v2 have been added. Do not change the defaults in production, they will bring your application down or at least fill your Sentry project up with nonsense events.

0.9.5

Do not use getargspec on Python 3 to evade deprecation warning.

0.9.4

Revert a change in 0.9.3 that prevented passing a unicode string as DSN to init().

0.8.1

Fix infinite recursion bug in Celery integration.

0.8.0

0.7.0

Properly display chained exceptions (PEP-3134).

Fix Tornado integration to work with Tornado 6.
Do not evaluate Django QuerySet when trying to capture local variables. Also an internal hook was added to overwrite repr for local vars.
