4.4 was the last one before they started to redo things.
... which - after quite a long wait - lead to the terribly disapointing update "Welcome Party" in May/June 2019. When I saw that, I thought the game was dead and done.
Then, despite frustration spreading, in November 2019, an update emerged, which actually was just another frustrating downgrade compared to what was finished before they decided on the remake. When I saw that, I thought the game was dead and done.
So, in a nutshell, this is why many people out here lost patience with the devs of this basically great game.
Trying to be fair, the rework of the artwork seemed to be kind of necessary, and then there was a big discussion about the new artwork which might have slowed the progres as well.
Having really enjoyed playing version 4.4. I am totally in favour of the dev continuing and finishing the game, but for an outstander it seems impossible to get why there is (so much) less content in the game than before after all this time.
Then again I am glad that they keep working on it. Still, all in all it's pretty annoying to follow this project. I wish Fresh Mulan and "Defenestration" all the best.
