Bonjour @Yann_Jouanique and thanks for making Kinyarwanda translations happen! I want to add that you can review translations in context by trying out the beta. I'll update those today or tomorrow.
In general, we update any translations available on Transifex when doing most betas and all releases. You can follow how betas are going and when releases are likely to go out by subscribing to the pre-release category.
