Release Notes
This page lists the currently published engine SDK package versions, download links, and checksums in IGP Developer Docs.
Each version has a fixed download link and matching SHA256SUMS. For production projects, always pin an exact version instead of using latest.
To see the concrete changes in each version, read Changelog.
Current latest versions: Unity 0.1.6, Unity Cloud Archive 0.1.4, GameMaker 0.0.6.
0.1.6 highlights:
- Unity hosted data-plane attach is now single-flight per
roomId + playerId, preventing duplicate descriptor requests and repeated KCP session replacement. - Unity Direct KCP only becomes connected after
kcp_handshake_ack; reconnect closes the old KCP session first, retries with500ms -> 1s -> 2s, and discards stale attempt callbacks. - Cloud Archive remains independently versioned at
0.1.4; current public versions are Unity0.1.6, Unity Cloud Archive0.1.4, and GameMaker0.0.6.
After downloading, you can use SHA256SUMS to verify the file:
sha256sum -c SHA256SUMSOn Windows you can also compare hashes with PowerShell:
Get-FileHash -Algorithm SHA256 .\cn.indiegp.sdk.unity-0.1.6.unitypackage

Upgrade guidance
Section titled “Upgrade guidance”Suggested upgrade rules while the packages are still in preview:
- Pin versions: record the exact Unity or GameMaker SDK version in use. Do not point to
latest/. - Keep a copy of old packages: back up previous
.unitypackageor.zipfiles before upgrading so rollback stays easy. - Verify the download: run
sha256sum -c SHA256SUMSafter downloading to confirm the file is intact. - Expect breaking changes: preview patch releases may still contain breaking changes. Release notes will call those out when they happen.
