New DLCS ? Just returned to Hitman after some years

Hi there fam !

Can someone explain to me what's up with the lastest DLCS/roadmaps on Steam ?

Le chiffre, The Splinter, The Dragon, Slim Shady, Patient Zero Requiem.

Those above mentioned I am aware some are roadmaps and some are DLCS but what is the difference between them ? And now what seems strange to me and I just noticed, a few months ago I saw the Slim Shady DLC on Steam and was like, nah ain't gonna buy it since I won't have time to play Hitman again right now. And today I saw there is a Milla Jovovich DLC out now and when I checked the page the Slim Shady DLC was gone !?

How does this even work ? Those are temporary DLCS ? Like grab it now because later you won't have the chance ? Is there any chance to grab the previous DLCS which are now unlisted ? or are they now implemented within the game for free or they will be at some point ?

Anyone has any info on this ?

Thank you in advance ! 🙏🏻
