  The source files attached to this release will not work due to our use of git submodules. Use one of the following methods instead:

  Using git

  To get this release, use the following commands:

  git clone -b v5.5.4 --recursive https://github.com/espressif/esp-idf.git esp-idf-v5.5.4

  Download an archive with submodules included

  Attached to this release is an esp-idf-v5.5.4.zip archive. It includes .git directory and all the submodules, so can be used out of the box. This archive is provided for users who have connectivity issues preventing them from cloning from GitHub. To reduce the size of the archive, the .git directory doesn't include the history of commits older than one year. Users who need to use git checkout to access an older release of IDF will have to use git fetch first to download the remaining part of the history.

  This archive can also be downloaded from Espressif's download server: https://dl.espressif.com/github_assets/espressif/esp-idf/releases/download/v5.5.4/esp-idf-v5.5.4.zip
