Lifecycle Policy

Version Lifecycle Timeline

Below is the lifecycle schedule for released versions of the Alauda Cache Service for Redis OSS:

Version	Release Date	End of Full Support	End of Maintenance
v5.0.x	2026-04-28	2027-04-30	2028-04-30
v4.1.x	2025-08-22	2026-08-30	2027-08-30

A new patch version of Alauda Cache Service for Redis OSS is released as needed to address bugs and security vulnerabilities. Patch releases do not introduce new features.
Minor and major version releases are driven by significant updates to the underlying Redis server, the implementation of new features, or emerging security requirements.

Each minor version progresses through two support phases over its lifecycle:

Full Support (Year 1): From the release date until the end of full support. The version receives all bug fixes and security patches via patch releases on the same minor line.
Maintenance (Year 2): From the end of full support until the end of maintenance. The version receives only critical bug fixes and security patches; non-critical fixes are not backported.

After the end of maintenance, the version is no longer supported. Customers should plan to upgrade to a supported version before this date.

During a version's supported lifecycle, Alauda provides the following services:

Upstream Patching: We actively track official Redis patch releases and promptly deliver critical bug fixes and security vulnerability patches.
Security Updates: We release security updates for the service operator on-demand to address vulnerabilities and ensure stability.
Upgrade Assistance: We provide dedicated support to help customers execute smooth and seamless upgrades to newer versions.
