TuyaOS Development Framework EOL Rules 

This article introduces the iteration rules of each version of TuyaOS and the cycle description of version End of Life (EOL).

Version Number Rules

The official versions released by TuyaOS are named with three parts: major version, minor version, and micro version. For example, 3.5.0, where the major version number is 3, the minor version number is 5, and the micro version number is 0.

•Major version: Updated when used for 架构 (architecture) upgrade.

•Minor version: Updated when new features are added or changed.

•Micro version: Updated when bugs are fixed.

For all development data version information about TuyaOS, please refer to TuyaOS EasyGo or check in Tuya Wind IDE > Resource Center.

EOL Cycle Rules

Each version's major and minor versions, such as 3.3, are supported for 36 months from the date of the first official version release. The support cycle includes the service period, maintenance period, and EOL period.

Service Period

During the service period of a version, it can be used to start new project development. At this time, only work such as bug fixing and compatible iteration of existing small features will be done, and no major new features will be added.

During the service period of a version, Tuya will take the initiative to update the micro version for bug fixing. For example, after the bug found in 3.3.2 is fixed, the version number will be upgraded to 3.3.3 or 3.3.4 (corresponding to the major version, and the micro version number of this version will be increased by 1). It is recommended to upgrade TuyaOS to the latest micro version of the current minor version for use.

Maintenance Period

During the maintenance period of a version, the version will still continue to be supported, but only bug fixes will be made for serious problems or security issues. It is not recommended to start new projects during this period.

EOL Period

During the EOL period of a version, it is recommended that users upgrade all projects to the latest TuyaOS version, and Tuya will stop bug fixing for the EOL version.

If there are customized function development or bug fixing requirements for the EOL version, please contact your account manager to customize the service.

Maintenance Status of Historical Versions

For subsequent versions of TuyaOS 3.8.0 and later, the release time will be marked in each new version development package, and all follow this specification, so that you can choose a suitable TuyaOS version for development according to the actual situation.
