# Release notes

Stratix releases ship across three artifacts. Each has its own changelog so you can subscribe to the surface you care about.

| Artifact                                                                                    | Where to read                                                                                                                                                                                                      | Cadence                                              |

## What ships in each

### Platform releases

Platform releases cover changes visible across all customer surfaces: new evaluation features, new judge / scorer kinds, dashboard improvements, billing / ECU changes, integrations.

* [**Latest releases**](https://github.com/LayerLens/gitbook-full/blob/main/13-reference/release-notes/latest.md) — last 30 days of platform updates
* [**Archive**](https://github.com/LayerLens/gitbook-full/blob/main/13-reference/release-notes/archive.md) — older releases by month

### SDK releases

The Python SDK at `layerlens` on the LayerLens package index ships independently from the platform. Each SDK release adds resource handlers, refines retry/timeout semantics, expands the auto-instrumentation adapter surface, or adds samples.

* [**SDK release notes**](https://github.com/LayerLens/gitbook-full/blob/main/13-reference/sdk-python/release-notes-sdk.md) — per-version changes
* [**SDK quickstart**](/6.-build-wire-your-code/quickstart.md) — install + first call
* [**SDK reference**](/13.5-operational/release-notes.md) — full API surface

### Samples

Each SDK release includes a refreshed set of canonical samples under `samples/` in the [stratix-python repository](https://github.com/layerlens/stratix-python/tree/main/samples). Samples are first-class — every recipe, tutorial, and reference page links into them.

Key sample directories:

* `samples/core/` — minimal end-to-end (quickstart, run-evaluation, compare-evaluations, async-workflow, paginated-results)
* `samples/integrations/` — auto-instrumentation samples (`openai_traced.py`, `anthropic_traced.py`, `langchain_instrumented.py`)
* `samples/instrument/` — manual instrumentation primitives for pipelines without a dedicated adapter
* `samples/cookbook/` — recipe-aligned samples that pair with [cookbook recipes](/2.-get-started/all-cookbook-recipes.md)
* `samples/cicd/` — drop-in CI/CD workflow files (e.g., `github_actions_gate.yml`)

## Subscribing

* **Platform** — RSS at the Latest releases page, optionally piped to Slack via Settings → Notifications
* **SDK** — watch the [stratix-python repository](https://github.com/layerlens/stratix-python) on GitHub, or subscribe to the LayerLens package index for version notifications
