[claude]

LGTM — straightforward version bump and AAR binary update.

Extended reasoning...

Overview

This PR bumps the DotNet SDK from 6.1.3 to 6.1.4, updating the Android native SDK from 5.7.6 to 5.7.7. The only text changes are a one-line version bump in OneSignalSDK.DotNet.nuspec and a one-line Android version bump in versions.json. The remaining 4 changed files are binary AAR replacements (core, in-app-messages, location, notifications).

Security risks

None. There are no logic changes, no auth/crypto code, and no new API surfaces introduced. The native change is a Kotlin downgrade (2.2.0 → 1.9.25) in the Android SDK, which is a bug-fix release on the native side.

Level of scrutiny

Minimal — this follows the exact same mechanical pattern as prior releases (6.1.3, 6.1.2, etc.). The diff is essentially two number changes and four binary file swaps.

Other factors

The one reported bug (Kotlin stdlib NuGet dependency version mismatch) is explicitly pre-existing and predates this PR. This PR actually reduces the gap — the prior release shipped AARs compiled against Kotlin 2.2.0 with the same 1.8.0.1 stdlib declaration. Multiple prior releases shipped with this pattern without apparent runtime issues, consistent with Kotlin's strong binary compatibility guarantees. This is not a blocker for this release.

[claude]

LGTM — the Kotlin stdlib has been updated to 1.9.23.3, addressing the previous feedback.

Extended reasoning...

Overview

This PR bumps the OneSignal .NET SDK to 6.1.4, updating the Android native SDK from 5.7.6 to 5.7.7. The key change in the native SDK is a Kotlin downgrade from 2.2.0 to 1.9.25. The diff touches: 4 Android binding csproj files, the main Android csproj, the nuspec, versions.json, 4 AAR binaries, and a deleted Cursor IDE rules file.

Security Risks

No security-sensitive code is touched. This is a version bump and dependency update with no auth, crypto, or permissions changes.

Level of Scrutiny

Low. This follows the same pattern as prior release PRs (e.g., 6.1.3). The changes are mechanical: version numbers incremented, binaries swapped, and dependency versions updated to match. The prior concern about Kotlin stdlib version mismatch has been fully addressed — Xamarin.Kotlin.StdLib.Jdk8 is now 1.9.23.3, consistent with the 1.9.25 Kotlin version used to compile the AARs.

Other Factors

No bugs were found by the automated bug hunting system. The previous inline comment was marked resolved, and the fix directly corresponds to the suggestion made. No outstanding reviewer comments remain.
