@ -70,7 +70,49 @@ As a general guideline:
- 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.
.. image:: ../chart.png
Each ESP-IDF major and minor release (V4.1, V4.2, etc) is supported for
30 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.
Support period is divided into "Service" and "Maintenance" period:
+-------------+--------------+---------------------------------------+
| Period | Duration | Recommended for new projects? |
+=============+==============+=======================================+
| Service | 12 months | Yes |
+-------------+--------------+---------------------------------------+
| Maintenance | 18 months | No |
+-------------+--------------+---------------------------------------+
During the Service period, bugfixes releases are more frequent. In some cases,
support for new features may be added during the Service period (this is
reserved for features which are needed to meet particular regulatory
requirements or standards for new products, and which carry a very low risk of
introducing regressions.)
During the Maintenance period, the version is still supported but only bugfixes
for high severity issues or security issues will be applied.
Using an “In Service” version is recommended when starting a new project.
Users are encouraged to upgrade all projects 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).
