Hi patrick,
I'm afraid we don't yet have any v4.3 release tag (you can view the list of tags here:
https://github.com/espressif/esp-idf/tags/), the latest is v4.3-beta2.
The pre-release tags so far are
v4.3-beta1 and
v4.3-beta2,
We have a "release branch" for v4.3 which is
https://github.com/espressif/esp-idf/co ... lease/v4.3
The naming is a bit regrettable, as "release/vX.Y" gives the impression that this is a release but actually this is a maintenance branch where the release will be tagged. So it's possible to check this branch out now, which will give you a revision somewhere between v4.3-beta2 and the final release. Or can stick with v4.3-beta2, and update to the v4.3 tag once the release is available (probably there will be a v4.3-rc soon and then the final release.)
(The reason we have the release branch is that master branch is already v4.4-dev with new feature development happening on it.)
There is a bit more about the "release branches" here:
https://docs.espressif.com/projects/esp ... sions.html
Does that all make sense?
