Do not call React, iOS, and Android languages.
Line 22 says “eight languages,” but Line 23 lists server languages together with the React framework and iOS and Android platforms. Datadog documents these as separate client-side SDK or platform integrations. Use “eight OpenFeature integrations across server and client platforms,” or split the language and platform counts.

Correct the Unleash provider count and list.
As of August 7, 2026, Unleash lists six maintained OpenFeature providers: Node.js, PHP, Python, Ruby, Rust, and Swift. The article says seven and lists Android instead of Swift. Update the count and list, or add an authoritative source for a seventh provider. (docs.getunleash.io)

| - **OFREP gained push updates.** Version 0.3.0 ([protocol#67](https://github.com/open-feature/protocol/pull/67)) added SSE event streams, and [protocol#77](https://github.com/open-feature/protocol/pull/77) accepted three ADRs covering push notifications, [cache-first local persistence](https://github.com/open-feature/protocol/pull/75), and [turning off default timer polling](https://github.com/open-feature/protocol/pull/69). | ||

Correct the operator release attribution.
Operator v0.9.0 was released on April 17, 2026. PR #807, which introduced native sidecars and dropped Kubernetes versions below 1.29, merged on April 23, 2026. The current sentence assigns the change to a release that predates it. (github.com)
Proposed wording
- Note that v0.9.0 moved to [native sidecar containers](https://github.com/open-feature/open-feature-operator/pull/807) and now requires Kubernetes 1.29 or later.
+ Note that the operator later moved to [native sidecar containers](https://github.com/open-feature/open-feature-operator/pull/807) and now requires Kubernetes 1.29 or later.📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

cc @cupofcat on this since we're talking a bit about Google - though I don't think anything here is controversial - just want to make sure you are in the loop.

LGTM. Adding a few others who's stuff is mentioned, just for visibility.
| The biggest news of the last year is not something we built. | ||
| Six well-known platforms launched feature flag services of their own, and each chose OpenFeature as a critical part of its product offering. | ||
