Returning player - how far has the game come since launch?

For context I played a disturbing amount of EU5 in its opening month - absolutely loved it. I eventually became frustrated with a few things and stopped playing around patch 1.0.7, namely:

• Colonialism/colony management was extremely clunky.

• The AI was pretty passive (although this was being tweaked around in a beta).

• The later Ages felt pretty unfinished, with the Age of Revolutions being borderline unplayable.

• Event triggers were often very obscure or bugged (e.g. Medici stuff in Italy, or most England's events).

• You had to manually marry off random nobles to sustain cabinet options.

There were plenty of other issues of course but most of them didn't seriously undermine my enjoyment (some erratic balancing re centralisation, wonky army balance, wonky trading).

I'm basically wondering if enough has changed on those bullet points to warrant revisiting the game or if I should hold off for now. Cheers.
