Yes, I've made several new invocations.
Book of Ancient Lore
Prerequisite: 5th level, Pact of the Tome feature
Your patron has inscribed spells into your Book of Shadows to aid you in your servitude. Choose one spell from the Bard, Druid, Sorcerer, Warlock, or Wizard spell list to add to your spells known. A spell you choose must be of 3rd level or lower, or a cantrip.
The chosen spells count as warlock spells for you. They don’t count against your number of spells known.
Book of Ancient Power
Prerequisite: 9th level, Pact of the Tome feature
You patron has imbued your Book of Shadows with a reserve of power that you can draw from as you need. You gain one additional warlock spell slot.
Book of Ancient Wards
Prerequisite: 5th level, Pact of the Tome feature
Within your Book of Shadows, you have discovered incantations to provide protection granted by your patron. When you take this invocation, you add Unseen Servant and Glyph of Warding onto your spell list. These spells count as warlock spells for you and do not count towards your normal number of spells known.
Book of Ancient Whispers
Prerequisite: 12th level, Pact of the Tome feature
When you need guidance from your patron, you can whisper your questions into your Book of Shadows. Your patron will answer through these pages as magical writing appears in a strange language only decipherable to you. Once you have read this correspondence, the writing vanishes, leaving only unfilled pages. When you take this invocation, you can cast Commune without using a spell slot. Once you have communed with your patron, you cannot use this ability again until you have finished a long rest.
Chain Master’s Command
Prerequisite: 5th level, Pact of the Chain feature
As an action, you can command your familiar to sacrifice itself in a blaze of destruction. It explodes and each creature in a 10-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes damage equal to 5 + your warlock level + your charisma modifier on a failed save, or half as much damage on a successful one. The damage type can be either radiant or necrotic, and is chosen when you gain this invocation.
If your familiar is killed, you can use your reaction to activate this ability immediately upon its death.
Once this invocation is used, you must wait until you have finished a long rest to summon a new familiar.
Eldritch Claws
Prerequisite: eldritch blast cantrip
Being within 5 feet of a hostile creature doesn’t impose disadvantage on your eldritch blast attacks.
Eldritch Warrior
Prerequisite: 15th level, Pact of the Blade feature
When you use your action to cast a spell or cantrip, you can make one weapon attack with your pact weapon as a bonus action.
I've also changed several of the current invocations, but this invocation in particular had the most significant change.
Gaze of Two Minds
Prerequisite: 12th level, Pact of the Chain feature
You can use your action to perceive through senses of a humanoid, celestial, fiend, or elemental until the end of your next turn. You must know the name of your target, and they must be on the same plane of existence as you. The target knows that you are seeing through its senses unless you want to remain hidden. The target receives a Wisdom saving throw once every minute to become aware of your presence. Celestials, fiends, and elementals have disadvantage on this saving throw. Once a target becomes aware that you are perceiving through its senses, it learns who you are and your location. An aware target may use an action to end the effect immediately. If a target chooses to end the effect, you cannot attempt this ability on that target for 1 week. As long as the creature is on the same plane of existence as you, you can use your action on subsequent turns to maintain this connection, extending the duration until the end of your next turn. While perceiving through the other creature’s senses, you benefit from any special senses possessed by that creature, and you are blinded and deafened to your own surroundings. While you do not need to know the location of the target to use this invocation, use of this invocation does not automatically inform you of the target’s location (though you may perceive clues as to the target’s whereabouts through its senses).
