Match-by-match ticketing: set prices per zone and per game, and run a season-ticket campaign.
Sponsorship: companies from every country with a league, and a preview with your kit and your court before you sign.
Satellite academies: run several around the world, and some kids arrive with dual passports.
Choose your building design: six new arena and training-complex designs.
Redesigned charts (attendance, season tickets, cash flow, career).

Improvements
AI clubs now feel promotion and relegation in ticketing and sponsorship, not just TV.
Market: AI clubs in the red recover more naturally.
New market rules: sanctions for clubs that break them and limits on transfers of minors.
Every country's youth system now occasionally produces players of other origins.
Injured players now also recover during the playoffs: a short layoff in the last round no longer costs you the whole postseason.
The opening Super Cup is played on court, and the Cup final at a neutral venue.
Older screens brought up to the style of the rest of the game.
Faster loading.
Fixes
The TV revenue breakdown appeared at the very top of the accounts.
Some academy youth player data wasn't being saved.
No more arenas with duplicate names.
From the Steam forum: the game no longer gets stuck with no active buttons mid-season.
