Thanks for your response.
I asked some french developper how to fixe it. In fact, you have to fill in the Header of the readmet.txt file with a line Stable tag: 2.3.16 under the line Tested up to: 4.4.
Maybe after it appears in GlotPress a Stable version and a Trunck version. You can see an example for bbpress. Yours only have truck version.
After that, everyone can contribue to plugin translation and you don’t have to include .mo of any languages. WordPress do that for you.
