TuyaOS Development Framework EOL Rules

Last Updated on : 2023-05-12 06:30:08download

This topic describes the TuyaOS release convention and end of life (EOL) cycle.

Release numbering

The release number consists of three parts: the major release, the minor release, and the patch release. For example, 3.5.0 is major release 3, minor release 5, and patch release 0.

  • Major release: This number is incremented when there is a new upgrade to the architecture.
  • Minor release: This number is incremented when there is a feature added or modified.
  • Patch release: This number is incremented when there is a bug fix.

You can check the release notes from TuyaOS EasyGo or Resource Center in Tuya Wind IDE.

Support lifecycle

Major and minor releases, such as version 3.3, receive support for 36 months from their initial official release date. The support cycle includes servicing cycle, maintenance cycle, and EOL cycle.

  • Servicing cycle

    You can use a release for new project development during its servicing cycle. During this cycle, the focus is on bug fixes and backward-compatible releases. Breaking changes are not added at this time.

    Additionally, patch releases will be issued as needed, to fix bugs and security issues. These are marked by incrementing the third part of the release number. For example, 3.3.3 or 3.3.4 is released to fix bugs introduced in 3.3.2. We recommend you update to the latest patch release of the minor release you are currently using.

  • Maintenance cycle

    During the maintenance cycle, support is limited to addressing critical bugs and security issues. It is recommended not to initiate new projects during this cycle.

  • EOL cycle

    During the EOL cycle, Tuya will discontinue all support for EOL releases. We recommend you update all the projects to the latest releases.

    If you require customization or dedicated bug fixes for EOL releases, contact your account manager for more information.
