With the new Errata, there have been changes to 8 units in the game. In this post, I'll show you the before and after changes so that you can easily compare them.
General Obi-Wan Kenobi
Allied Units do not lose their hunker when they become Engaged and can gain and have hunker while they are Engaged. While an allied Galactic Republic Unit has one or more hunker, it adds 1 die to its defense rolls agains melee attacks. After an attack targeting a character in an allied Galactic Republic Unit is resolved, that character's Unit may remove all its hunker. If it does, one character in that unit may heal for each hunker removed. Then each character that heal may dash.

If it does, one character in that unit may heal for each hunker removed. Then each character that heal may dash.
Change: I think this is just a clarification on when the effect is active.
Cad Bane, Notorious Hunter
After another allied Unit makes a combat action, if this Unit is not Engaged, it may use this ability. Choose one of the targeted characters within range 4. One character in this Unit deals damage damage to the chosen character. If none of the targeted characters are within range 4, each character in this Unit may jump Toward one of the targeted characters.

Change: It seems like the first line got changed. This might be to future-proof the ability for units with multiple characters.
Aurra Sing
When a character in this Unit makes a ranged attack as part of a combat action, if the defender is Engaged with one or more allied characters in Units that are not Wounded, it may add 3 dice to its attack roll. If it does, choose one of those Engaged allied Units. The chosen Unit suffers damage damage.

Change: The change is in the last two line. You are now targeting and damaging the character instead of the unit.
Greef Karga
Before revealing the top card of the Mission Deck, choose an opposing player to reveal cards from the top of their Order Deck until a Unit Order Card is revealed. Then the chosen player marks the corresponding Unit with a Priority Objective token and shuffles their Order Deck.
The first time an allied Bounty Hunter character Wounds the market Unit, move the Struggle token one space toward your Momentum tokens. Then remove the Wounded Unit's Priority Objective token.

Change: The change is that you are now only able to activate this ability before revealing the first card instead of the top card.
Paploo, Curious Creature
When a character in this Unit makes a melee attack targeting an enemy character that has exposed or pinned, the attacking character may use the target character's melee Expertise Chart during that attack, instead of its own.
->
When a character in this Unit makes a melee attack targeting an enemy character that has exposed or pinned, the attacking character may choose to use the defender's melee Expertise Chart, instead of its own, during the Apply Expertise Charts step of that attack.
Change: Targeted character melee expertise chart got changed to defender's melee expertise chart. It also specified in which step this occurs.
Obi-wan Kenobi, Out of Hiding
When an allied character within range 3 is targeted by an attack, this Unit may use this ability. The attack ends. If it is the attacker's activation, it may make another attack targeting a different character. If it does, remove 2 dice from the attack roll.
->
When an allied character within range 3 is targeted by an attack, this Unit may use this ability. Cancel the attack. If it is the attacker's activation, it may make another attack targeting a different character. If it does, remove 2 dice from the attack roll.
Change: The attack now gets canceled instead of ending.
Crosshair
When a character in this Unit makes a ranged attack as part of a combat action, before dice are rolled, this Unit may use this ability. During this attack, each time the attacker would resolve a heal, it may instead choose to remove one condition from an allied Unit that is Engaged with the defending character.

During this attack, each time the attacker would resolve heal, it may instead choose to remove one condition from an allied character that is Engaged with the defender.
Change: The target of the condition removal is now a character instead of a unit. Also defending character is now defender, but I don't think this will change anything.
Wicket, Intrepid Warrior
Action: Each enemy Unit within range 3 that is not Engaged gains pinned. Each enemy unit within range 3 that is Engaged gains exposed.
->
Action: Each enemy Unit within range 3 that has no Engaged characters within range 3 of a character in this Unit gains pinned. Each enemy Unit that has one or more Engaged characters within range 3 of a character in this Unit gains exposed.
Change: I assume this clarification is done for future troops that have multiple characters.
And those were all the errata on the characters. They aren't very exciting, but it is good to see what has changed. The characters will also be updated in the database, but currently won't be able to update the images of the characters.
