The only thing you have to do is acquire the Voidheart charm, then make use of a new special interaction during the final boss. As for getting that charm, you need to get both halves of it:

One is in the Queen's Gardens. After getting Shadow Dash, go to top-left of the queen's gardens past a void wall, defeat the Traitor Lord, and talk to the character past that.

The other is in the Ancient Basin. You need to get 1800 Dream Essence to awaken your dream nail to let it pierce into protected minds. Then, go to the old palace in the right of the Ancient Basin and dream nail the dead guard. You then need to complete a lengthy section of platforming: I'd recommend using either Hiveblood or Grubsong+Deep Focus to keep yourself from dying. The path inside the dream is mostly linear, only a couple places with options.

There is also another pair of endings added in the final major update that some may consider the new "true ending", but that is a very long ways away for you at the moment, and probably requires the normal "true ending" to be done first anyways.

There is no "true" ending
But for "Sealed Siblings" And "Dream No More" endings
You need to get the Awaken dream Nail (1800 Essence)
Make your Way to the Ancient Basin for the Monarch Wings (Double Jump)
You need to find and Beat Hornet a 2nd Time for the Kings Brand
With it you can go to the Abyss to get the Shade Cloak.
Make you way to Queen Garden and Find Mommy (The White Lady) for half the King Soul Charm.
Go to the Palace Ground and Dream nail the King Mold to enter the White Palace and Find Daddy (the Pale King) for the other half Of the King Soul.
Return to the Abyss with the King Soul equipped, and Find your Egg and Dream nail it.
Now you have the Void Heart.... Now go fight the Hollow Knight.
