Hello.
I don’t know if this is the right place to say the errors in the documentation.
But, in the French translation I found an error which caused me enough confusion.
in La contrainte Stretch To — Blender Manual paragraph 3:
(rappelez-vous que l’axe X local d’un os est aligné sur lui, de la racine jusqu’à la pointe).
In English
(remember that the local Y axis of a bone is aligned with it, from root to tip).
The French documentation indicates the X axis as the director.
I tested other translations, only the French translation has this
