  Arduino Pre-Release v4.0.0-alpha1 based on ESP-IDF v6.0.1+ Stable

  petr.gadorek released this 2026-05-27 16:24:26 +00:00 | 120 commits to master since this release

  This pre-release is basically the same core as 3.3.9, but with pre-compiled libs from ESP-IDF release/v6.0 branch and newer toolchain.

  Due to incompatibilities with ESP-IDF6, some of the components are not yet available. Most notable are:

  • Matter
  • RainMaker
  • ESP_SR
  • Insights
  • Cbor
  • Any component that those depend on
