The Quality Assurance Team Blog, commonly referred to as the QAT Blog, was a semi-regular blog written by members of the Quality Assurance Team. Beginning in August of 2016, they discussed not only the activities of the QAT, but a variety of other topics spanning osu! gameplay, mapping, modding and the game/community as a whole.
In September of 2017, the QAT blog was discontinued in favour of the QAT Gazette series which was posted on the news feed. All earlier posts on the blog were retroactively ported to osu!news afterwards.
