Well, the Spanish blues are not stopping with the release of Patch 3.1, this news is something that we already knew but that provides some more information about the mechanics that Blizzard will follow when improving or introducing new bottles / potions / consumables.
You may already know that the Stoneblood Vial has been improved in the Trial Realm, but in case not, we want to tell you that we felt that the current amount of life this vial provides was ridiculous because of how low it was, especially considering the boss damage in Ulduar, so we've improved it. Keep in mind that we don't like the idea that every new bottle / upgrade is something with the same stats and increased numbers. As an example, the next Tank Flask might have the same or lower health, but extra mitigation attributes like armor or defense.
Here you have the 2 Vials of Bloodstone:
BEFORE
AFTER
As you can see, they have doubled the amount of life that the bottle in question grants.
