The latest support policy for ESP-IDF can be found at [https://github.com/espressif/esp-idf/blob/master/SUPPORT_POLICY.md](https://github.com/espressif/esp-idf/blob/master/SUPPORT_POLICY.md)
|
|
|
|
Support Period Policy
|
|
=====================
|
|
|
|
Each ESP-IDF major and minor release (V4.0, V4.1, etc) is supported for
|
|
18 months after the initial stable release date.
|
|
|
|
Supported means that the ESP-IDF team will continue to apply bug fixes,
|
|
security fixes, etc to the release branch on GitHub, and periodically
|
|
make new bugfix releases as needed.
|
|
|
|
Users are encouraged to upgrade to a newer ESP-IDF release before the
|
|
support period finishes and the release becomes End of Life (EOL). It is
|
|
our policy to not continue fixing bugs in End of Life releases.
|
|
|
|
Pre-release versions (betas, previews, `-rc` and `-dev` versions, etc)
|
|
are not covered by any support period. Sometimes a particular feature is
|
|
marked as \"Preview\" in a release, which means it is also not covered
|
|
by the support period.
|
|
|
|
The ESP-IDF Programming Guide has information about the
|
|
[different versions of ESP-IDF](https://docs.espressif.com/projects/esp-idf/en/latest/versions.html)
|
|
(major, minor, bugfix, etc).
|
|
|
|
Long Term Support releases
|
|
--------------------------
|
|
|
|
Some releases (starting with ESP-IDF V3.3) are designated Long Term
|
|
Support (LTS). LTS releases are supported for 30 months (2.5 years)
|
|
after the initial stable release date.
|
|
|
|
A new LTS release will be made at least every 18 months. This means
|
|
there will always be a period of at least 12 months to upgrade from the
|
|
previous LTS release to the following LTS release.
|
|
|
|
Example
|
|
-------
|
|
|
|
ESP-IDF V3.3 was released in September 2019 and is a Long Term Support
|
|
(LTS) release, meaning it will be supported for 30 months until February
|
|
2022.
|
|
|
|
- The first V3.3 release was `v3.3` in September 2019.
|
|
- The ESP-IDF team continues to backport bug fixes, security fixes,
|
|
etc to the release branch `release/v3.3`.
|
|
- Periodically stable bugfix releases are created from the release
|
|
branch. For example `v3.3.1`, `v3.3.2`, etc. Users are encouraged to
|
|
always update to the latest bugfix release.
|
|
- V3.3 bugfix releases continue until February 2022, when all V3.3.x
|
|
releases become End of Life.
|
|
|
|
Existing Releases
|
|
-----------------
|
|
|
|
ESP-IDF release V3.3 and all newer releases will follow this support
|
|
period policy. The support period for each release will be announced
|
|
when the release is made.
|
|
|
|
For releases made before the support period policy was announced,
|
|
the following support periods apply:
|
|
|
|
- ESP-IDF V3.1.x and V3.2.x will both be supported until October 2020.
|
|
- ESP-IDF V3.0.9 (planned for October 2019) will be the last V3.0
|
|
bugfix release. ESP-IDF V3.0.x is End of Life from October 2019.
|
|
- ESP-IDF versions before V3.0 are already End of Life.
