I'm sorry for any confusion. Not all patches have player facing changes and thus do not require any patch notes. Patch notes are intended to provide players with an idea of changes they should expect to see. However if the changes are all in the backend or are for future content, there's nothing to note for players.
As Stayboy mentioned, there's often a delay on our release our notes because we're busy making sure all is well with the changes. However if there is something player facing, we do try to get them up as we have time.
As you previously stated, you were in discord. It was speculated that the update was nothing but to remove the vendors. The updates were also very small so no real content could have been added. Also, i dont know how long you've been around but they take their time on patch notes and this is normal. No need to complain now.
