Release Process Information

ESP-IDF Dependency

Arduino is built on top of ESP-IDF. This is important to realize that ESP-IDF release schedule changes affect and impact Arduino for ESP32 Releases (both the core and the component). It is important to always evaluate ESP-IDF Plans.

Release Stages

  • Planning: preparations, evaluation if the dates can be kept. Project is branched from master. Usually 1 week.
  • RC1: First release candidate, will only accept critical bugfixes. Feature Freeze. Usually 2 weeks.
  • RC2: Second release candidates, will only accept blocking bugfixes. Usually 2 weeks.
  • Release: Date of Release tag.

Release Scheme

  • Releases follow the format: Major-Minor-Fixes (x.y.z)
    • Major: ESP-IDF major update or breaking changes (along minor changes, new features and fixes).
    • Minor: ESP-IDF minor update, addition of new features (along all fixes).
    • Fixes: bugfixes only.
  • The launch of a new Major/Minor will replace the previous release.
  • Arduino for ESP32 Releases do not outlive the ESP-IDF they were built upon.
  • Back-ports of Arduino Releases are evaluated on case by case.
  • No back-ports over outdated/unsupported ESP-IDF releases.

General Information

  • Arduino for ESP32 and Arduino Component for ESP-IDF follow the same release schedule.
