Release Notes (Stable Version)

Note

Only the IM SDK for Android/iOS platforms has development and stable versions.

Design Principles​

The iOS platform provides stable versions of the IMLib SDK and IMKit.

  • The stable version of the SDK meets certain metrics in terms of online runtime, stability, and usage volume.
  • It emphasizes stability over introducing new features.

Release Cycle and Version Number Rules​

The IM SDK has different version number rules before and after version 5.4.X. After 5.4.X, it's easier to distinguish between development and stable versions.

  • Starting from version 5.4.X and later, the Stable version occupies the second digit of the version number. If the second digit is even, it’s a development version; if it’s odd, it’s a stable version. For example, 5.5.X is the version number used for the stable SDK.
  • Before 5.4.X, the version number rules for stable versions were not fixed.
  • RC monitors the usage of Stable versions by customers and updates the stable version regularly, with the longest update cycle being two months.

Maintenance Notes​

  1. If RC releases a new Stable version under the major version number (currently 5.X) that is actively being developed, we recommend that customers using the Stable version upgrade to the new Stable version. After the release of a new Stable version, the maintenance of historical stable versions will be reduced accordingly.
  2. For historical major versions (2.X, 4.X) of the SDK that are no longer actively developed, RC maintains only one Stable version. Customers still using 2.X or 4.X versions are advised to upgrade to the corresponding Stable version or consider upgrading to the 5.X series SDK.

The 5.7.x series is a stable version based on the 5.8.0 Dev version.
