Possible bug - release notes identical for last three beta versions in a row

This is on Windows, betas 4264, 4276, and now 4282. Are you guys just not updating this, or is something wrong with the update mechanism?

I think you meant 4274, not 4264.

There was a problem with 4274, so 4276 was released which removed those changes. 4282 fixed this bugs so the notes are not correct.
