Also note sight-stones (3 wards per back, 5 if upgraded) are good for supports, lee, and anyone else who places a lot of wards (over 11 while you have it, and factor in the menu cost of not having other items when you decide to get this) if you're not a support/lee, taking up an inventory space like this can be cumbersome late-game so you probably want to rely solely on your warding trinket as your build's finishing up.
Icebourn Guantlets are a big one, if you use a spell, your next basic attack will create an icy field around your target slowing them and others nearby as well as inflicting extra damage.
Aegis of Legion was reworked, it now has an upgraded version, the upgraded versions active grants a shield for your allies.
There are numerous ways for supports to get gold now, look under gold income; Talisman of Ascension (final version of Ancient Coin) provides a substantial speed boost to you and nearby allies, very useful for quick escapes/engaging someone mildly out of position/getting to a fight that started without you.
There are some fun items like Runaan's Hurricane which gives a huge attack speed boost and fires a 50% physical damage shot to two extra enemies when you hit one. Really only useful if you have a ranged attack with passive on-hit effects (YAY TEEMO!) and benefit from attack speed.
Ravenous Hydra is great for bruisers with its on-hit AOE passive, high damage, and reasonably high life steal.
Oracles elixir was removed
you'll be hardpressed if you need continuous invis reveal but getting a trinket that drops vision wards (now visible to enemies) helps, especially if you drop it during a fight with Akali.
I'm probably forgetting a lot of important things but hopefully this helps.
