Patch 2.3.0 is currently in development and now available for testing on the PTR. To learn about major changes included in 2.3.0, please see the official PTR patch notes. For information on how to participate, copy over characters, and provide feedback, read on below!
Further details on how to access the PTR and use the Character Copy system can be found in the FAQ.

To participate in the public test, you must have a Diablo III game license attached your Battle.net account in good standing (i.e. it hasn't been suspended or banned). In addition, you will also need to download and install the Battle.net desktop app if you have not already done so.
Step 1: Create a PTR account. To create a PTR account, log in to Battle.net Account Management and double-click on your Diablo III game license; this will bring you to the game management page. On this page, click "Create a PTR account."
If you've participated in any previous Diablo III PTR (including the Reaper of Souls beta), the "Create PTR account" button may not appear. This is because you've already created a PTR account and can therefore skip this step.
Step 2: Once you have created a PTR account, installed the Battle.net desktop, and logged in with your Battle.net credentials, select "Diablo III" from the main menu on the left-hand side of the application.
Step 3: On the Diablo III screen, there is a drop-down menu right above the "Play" button (note that this may say "Install" if you do not have Diablo III currently installed). Select "PTR: Diablo III" from this drop-down menu before proceeding.
Step 4: You should now have the option to install and play the patch 2.3.0 PTR.
The 2.3.0 PTR is available in all supported languages, and accounts from all regions are eligible to participate.

The option to copy your existing Diablo III characters from your live account to the PTR will be available and can be done directly through the PTR client. However, only one region per account can be copied at a time. So, if you choose to copy characters from your account in a different region, any previously copied PTR characters will be lost.
Step 1: Log into the live game and then log out.
Step 2: Log into PTR client and create a level 1 character. After you're done, return to the main character screen.
Step 3: Click on the "PTR Copy" button located in the upper right-hand corner. (The PTR Copy button will not appear in-game until you have created a new level 1 character.)
Step 4: Select your region.
Step 5: Click "Copy." This will copy all characters on your account from the selected region.
Step 6: You will be disconnected from the PTR client.
Step 7: Log back in. Your copied characters will be available for play.
Please note that you can only copy characters from one gameplay region at a time. If you choose to copy characters from a different region, any previously copied PTR characters will be lost. In addition, you can only copy characters over to your PTR account once every 24 hours. Attempting to copy characters before this cooldown is up will result in an error.
As a reminder: Any progress made on the PTR will not transfer over to your live account.

Once you've had the chance to try things out, be sure to visit the Public Test forums to discuss the patch.
As this is a test server, please anticipate uneven game performance, and note that restarts and downtime may occur without warning.
The Public Test Realm for Patch 2.3.0 is right around the corner! Are you ready to feast your eyes on all the new goodies that await you in the world of Sanctuary? There’s a lot to cover, so let’s get started.
As always, please note that this is only a preview. The below information does not reflect all changes available in Patch 2.3.0 and is subject to change. Some images represent works in progress, and may not be representative of the final product.
In Patch 2.3.0, the frozen wasteland that is the Ruins of Sescheron will open for exploration. Here you’ll face off against strange new enemies and perilous environmental hazards, all while unearthing new mysteries from the lore of the mighty Barbarians. Those brave enough to make it through in one piece will discover curious new points of interest, including the lost Tomb of King Kanai and his ultimate treasure—Kanai’s Cube.
Those who played Diablo II might remember the Horadric Cube, a unique device which allowed you to combine items. Useful as it was, it was easily surpassed in power by the item from which it originated, Kanai’s Cube. In Patch 2.3.0, players will be able to discover this powerful ancient relic and utilize its incredible potential, including the ability to break down Legendary items and equip their special effects as passive skills (which are separate from your other passive skills), convert crafting materials from one type to another, and so much more.
For those who eagerly gather crafting materials on their journey to level 70, we’ve got good news you’ll especially enjoy. Starting in Patch 2.3.0, the same crafting mats you use at max level will be available as you level up! We’ve also crunched down the number of crafting recipes, making the process easier and more fluid than ever as your results now dynamically adjust to your character’s level. Whether you’re bashing skulls on the highest difficulty or have just started your career and killed your first Champion or Elite pack, your crafting mats will never go to waste.
This patch also includes changes designed to improve the pacing of Adventure Mode while encouraging players to explore Bounties across a variety of Acts. In addition to removing the Realm of Trials, we’re improving Bounty rewards by adding new Act-specific crafting mats to Horadric Caches. Completing Bonus Acts in Adventure Mode games will also now grant a bonus Horadric Cache stuffed with crafting materials, gold, and additional Act-specific crafting mats.
Every player’s Seasonal journey is different—and so are their accomplishments. Starting in Season 4, you'll be able to track your individual progress through the Season Journey interface. This helpful feature is divided into Chapters, which include major milestones that are achievable by most players, and Tiers, which are designed for advanced players. Completing Tiers unlocks new portrait frame rewards, and the highest Tier includes challenges which will take effort to achieve for even the most powerful nephalem.
As players continue to discover powerful new gear, the current hardest difficulty level—Torment VI—can begin to feel less challenging. To help keep hardened battle veterans on their toes, we’re adding four new Torment levels with appropriate reward rates, including Torment X. We’ll be iterating on these new difficulties and rewards as the PTR progresses, so we look forward to hearing your feedback!
For all you dedicated loot hunters, we’re also adding lots of shiny new Legendary and Set effects to the game. Aside from doing this through introducing new items, we’re also revamping special effects on some existing items, and granting new effects to some items which don’t currently have one. As in other patches, changes to Legendary items are not retroactive, so you’ll need to find them once more to use their updated form. Overall, this should result in more build options for you to explore.
Several changes to monsters are coming to the game as well. Along with reducing the amount of crowd control the game’s tougher monsters will tolerate, we’ve adjusted the experience and Rift progress granted by killing monsters so they better reflect the effort required to kill them. For example, monsters that take more time or effort to kill now provide more experience, and those that are especially easy to kill will provide less. We’ve also made changes that create a better balance between the time you spend exploring and clearing Nephalem or Greater Rifts, and the time you spend facing the Rift Guardian. With these changes, more of the emphasis will be on your journey as you explore and clear the Rift.
New zone, new Cube, new items, new difficulty levels, new Adventure Mode changes—the list goes on and on! We hope you’re looking forward to trying out all these new features and leaving your valuable feedback once the PTR hits.
Out of all that you’ve seen above, which of these changes are you most excited to experience for yourself? Let us know in the comments, and we’ll see you on the Public Test Realm!

We've recently herd rumors of an invasion. Not one of a demonic nature, mind you, for those we are quite accustomed to. No, these rumors allege that townships throughout Khanduras are being overrun by bipedal, bardiche-bearing bovine who are luring weary adventurers to the proverbial slaughter through moosterious orange portals.
Many of you have expressed fear. Some have asked if you should moov your families. To this we say: Hold fast. There is no cause for alarm. We've seen the so-called "evidence" being pastured around local inns and, after thoroughly investigating all reported sightings, can cowfindently state that this is nothing more than a clever hoax.

On the left is the "imaginative" artist rendition of the threat.
On the right is the truth of the matter and what we actually found after proper inspection.
There are no homicidal heifers. There is no invasion. And, more specifically, there is no cow level. Anyone who claims otherwise is full of bull and simply milking this terrible prank for all that it's worth.
That said, while the idea of some sort of "cowpocalypse" (as one terrified farmer has taken to calling this) is udderly ridiculous, it is worth noting that one can never be too careful. And so, after consulting with our local Horadrim chapter, we have elected to issue an advisory.
Effective immediately, we encourage all residents of Sanctuary to steer clear of the wilds. From dawn on May 15 to dusk on May 21, it is also recommended that you avoid entering any strange portals that may or may not lead to alternate planes of existence. This activity cud be potentially hazardous to your health and, in the opinion of this humble civil servant, is a veally bad idea in general.
In the meantime, we urge you all to stay calm and remember that cows don't kill people. Everything ELSE in Sanctuary kills people.
Thank you,
