Support Periods

---------------

Each ESP-IDF major and minor release version has an associated support period. After this period, the release is End of Life and no longer supported. Some releases are designated Long Term Support, which means the support period is longer than for other releases.

As a general guideline:
|
||||
|
||||
- Using Long Term Support releases will maximize the amount of time between required ESP-IDF major or minor upgrades.
|
||||
- Using standard stable releases will require more frequent upgrades to new ESP-IDF versions. However, this means that new features and major improvements will be available more frequently.
|
||||
|
||||
It is also possible to upgrade from a Long Term Support release to a standard release, and vice versa.
|
||||
- If starting a new project, use the latest stable release.
|
||||
- If you have a GitHub account, click the "Watch" button in the top-right of the `Releases page`_ and choose "Releases only". GitHub will notify you whenever a new release is available. Whenever a bug fix release is available for the version you are using, plan to update to it.
|
||||
- If possible, periodically update the project to a new major or minor ESP-IDF version (for example, once a year.) The update process should be straightforward for Minor updates, but may require some planning and checking of the release notes for Major updates.
|
||||
- Always plan to update to a newer release before the release you are using becomes End of Life.

支持期限
|

---------------
|
||||
|
||||
ESP-IDF 的每个主要版本和次要版本都有相应的支持期限。支持期限满后，版本停止更新维护，将不再支持。
|
||||
|
||||
`支持期限政策`_ 对此有具体描述，并介绍了每个版本的支持期限是如何界定的。

`发布说明页面`_ 界面上的每一个发布版本都提供了该版本的支持期限信息。

一般而言：
|
||||
|
||||
- 如您刚开始一个新项目，建议使用最新稳定版本。
|
||||
- 如您有 GitHub 账号，请点击 `发布说明页面`_ 界面右上角的 "Watch" 按键，并选中 "Releases only" 选项。GitHub 将会在新版本发布的时候通知您。当您所使用的版本有 bugfix 版本发布时，请做好升级至该 bugfix 版本的规划。
|
||||
- 如可能，请定期（如每年一次）将项目的 IDF 版本升级至一个新的主要版本或次要版本。对于小版本更新，更新过程应该比较简单，但对于主要版本更新，可能需要细致查看发布说明并做对应的更新规划。
|
||||
- 请确保您所使用的版本停止更新维护前，已做好升级至新版本的规划。
