Overview of ESP-IDF 5.1 Support

[VojtechBartoska]

This issue tracks work progress for support of ESP-IDF 5.1.

General explanation

Current version of Arduino ESP32 Core with numbering 2.X.X are based on ESP-IDF v4.4. ESP-IDF 5.0 is already released and we are working on porting our Arduino Core to be based on ESP-IDF 5, more precisely we are heading to upcoming ESP-IDF v5.1.

ESP-IDF v5.0 includes braking changes, refactoring of some of the peripherals and drivers. For more details, take a look on Migration Guides.

Branches & Releases of Arduino Core

We'll release few bug fix versions 2.0.X. After last release, first initial Pull Request including ESP-IDF 5.1 changes will be merged into Master branch and we'll be work on ESP-IDF 5.1 support in Master branch.

If we decide to do one more bugfix release 2.0.X, fixes will be cherrypicked and merged manually into v4.4 branch. We are not going to add any new features to version 2.X.X.

Progress

This table will be kept up to date.
