The date shown here conflicts with fastText's own official release history.

• The official fastText announcement post is titled "Releasing fastText" and is dated August 18, 2016. In that post, Facebook AI Research says it "is open-sourcing fastText", indicating the public release happened then, not in November 2015.
• fastText's official blog page also says "When fastText was first released in 2016".
• A later official post says "First open-sourced last summer" in a May 2, 2017 article, which again places the initial public release in 2016.

So the infobox's release date of November 9, 2015 is inconsistent with the project's own official materials, which place the first public/open-source release in 2016 (specifically August 18, 2016).
