Apart from that, Hitman will receive a small renovation next week already: on October, 13th ten new contracts arrive in the game, as well as five new challenges and one unlockable item. The big announcement may or may not be related to featured player-curated contracts; in any case, these will be included in the game later this month as well.
The players-curated contracts feature was introduced in August. A chosen member of the community goes throw a list of contracts submitted by others and makes a list, suggested to play regularly each month.
Hitman was entirely released in January 2017 in and stood out in the series with its episodic model — hence the upfront 'season' clarification made in IOI's blog. We will keep our eyes on news for further updates.
