"This autumn" was said in Discord. But as you probably know, autumn has variable definitions depending on what geological zone you look it from. At the
Northern temperate zone, the autumn can be defined in three different seasons: in
"astronomical season" autumn is the time between September 22nd or 23rd and December 22nd, in
"meteorological season" autumn is the time between September 1st and November 30th, in
"solar (Celtic) season" autumn is the time between August 1st and October 31st. At the
Southern temperate zone, in
"astronomical season" autumn is the time between March 21st and June 21st, in
"meteorological season" autumn is the time between March 1st and May 31st, in
"solar (Celtic) season" autumn is the time between February 1st and April 30th.
So, depending on which season and temperate zone Lewdlab decides to choose the definition for the autumn that he was talking about in Discord, the release can be anytime between now all the way to June 21st 2023. "Work smart, not hard" seems to be the favourite quote of Lewdlab.
