D&D Online: Patch Notes @ Official Site

The patch notes for the newly released solo content are available at the official Dungeons and Dragons Online site.

Experience Table Adjustment

In conjunction with the new solo options for the Harbor, we have made some adjustments to the experience required to get from level 1-3. Advancing to level 2 will now require 5,000 experience points instead of 10,000, and advancing to level 3 will require 20,000 total experience points instead of 30,000, allowing you to visit the trainers even earlier.

As a result of this sliding experience, the experience point requirements for level 3-10 will be 10,000 points lower. The amount of experience required to move from level 3 to level 10 will remain the same, but will require less total experience, as a result of the changes made at levels 1 and 2. To balance this out for existing characters, all characters who are currently level 3 and above will see a one-time, 10,000 point, experience shift closer to their next level. Please note: this is NOT a gift of 10,000 xp, merely a shift however depending on your current xp total this may grant you a new level or rank.
