Le CHANGELOG n'est pas bon.

[pylapp]

Cette ligne n'a rien à faire dans la section pour la v0.6.0 qui a été livrée.
Il doit être dans une sous-section "Fixed" dans la section "Unreleased", je t'ai déjà fait la remarque la semaine dernière.

Je note que ta PR modifie d'une part effectivement l'a11y mais aussi met à jour la déclaration d'accessibiltié.
Comme j'ai déjà pu te le dire, il faut que ton CHANGELOG reflète ce qu'apporte ta PR.
Change la ligne du CHANGELOG pour indiquer que tu mets à jour la déclaration (en plus de corriger ton bug).
