Here are the Release Notes for Update 23.5, released on Tuesday, April 23rd.

Burglar
The overall goal is to increase the Burglar's general damage output, fix some structural issues with their skills, improve their group survivability, and streamline some of their play.
Damage on most skills has been increased and shuffled in an attempt to put more skills in a more appropriate range of DPS.
All melee skills have had their range increased to a minimum of 3.5.
Most of the Burglar's skills have had their "Fast" trait removed, but this only really had an effect when the prior skill had an execution time longer than its animation time.
Subtle Stab is still "Fast" so you can more easily see which skills are being shortened.
Double Edged Strike is now an immediate skill.
Find Footing is now Instant.
Provoke now has a 15 meter range and a six second cooldown.
Provoke now provides a 20% crit chance bonus on your next attack, similar to a lesser "aim" effect.
Provoke provides a stacking (x3) self buff that halves the damage of the next attack against you.
Provoke no longer penalizes your party's crit chance against the target by 2%.
Mischievous Glee now heals for 10% of max health.
Self Adulation now adds 20% to Clever Retort healing.
Both Double Edged Strike and Flashing Blades are now area of effect skills (3 targets).
Coup de Gras no longer has a critical magnitude bonus, but does better base damage. Its cooldown has been reduced from sixty to thirty seconds.
Feint now allows you to trigger more stealth effects and bonuses of other skills, though it still does not provide true stealth's melee damage bonus.
Knives Out has been changed to provide a small radius Force Taunt that lasts for the duration of the effect, followed by an aggro dump that reduces aggro in a similar radius.
Knives Out now mitigates all forms of incoming damage, instead of just melee damage. Damage reduction has been increased from 80% to 85%.
Cunning Strike bleeds are now shorter duration non-stacking bleeds that apply at four different magnitudes, depending on how hard you crit +1 from stealth.
Cunning Strike Bleed duration has been reduced.
Gambles have been substantially reworked.
You can now have one gamble of each type on a target simultaneously.
The skills Gambler's Strike, Hedge Your Bet, and Blind Bet now apply each of these gambles respectively.
A blue line Burglar stealth surprise attack will apply a random gamble.
Gambles can no longer be tiered up or down, and simply roll a new 1-6 value when re-applied.
Gambles now last a base 30 seconds.
Cash Out consumed all Gambles on a target, granting a high magnitude damage effect, a self heal over time, and a stun, respectively.
Cash Out's cooldown is now a base of 40 seconds.
Note: Gambles are NOT per Burglar, but rather per Target, so competing Burglars will overwrite or consume each other's Gambles.
Gamble icons have been changed.
Subtle Stab's cooldown has been reduced to 2.5 seconds.
Gamble Chance mods have been changed to Gamble Damage mods.

Known Issues:

The buffs received from the blue line Burglar trait 'Even the Odds' are not currently stacking.
Vigilant/Thunderous Roar legacy is not providing correct Incoming Healing increase yet.
The yellow line Burglar trait Self Adulation incorrectly states that it adds +5 pulses to Mischievous Glee.
