Turbine has released the book 8 patch notes, please not that this is the test server notes only and will probably change before the actual update come out.

"Welcome to The Lord of The Rings Online: Mines of Moria™ Book 8 Preliminary Release Notes! Please be aware that these notes are for the Bullroarer test server ONLY and are not complete or final. They will be revised and updated when Book 8 goes live on the LOTRO servers in June. Enjoy! "

Here are some of the highlights of the realease notes:

Summer Festival

The Summer Festival, coming in Book 8, now has two new events -- one in the Shire, on The Hill, and the second on the approach to Thorin's Hall.

Crafted Equipment minimum level usage requirement changed

Certain crafted equipment items had their minimum level usage requirement changed for Book 8. However, bound items in the player's possession which were changed to exceed the player's level will instead match the player's level. Non-bound and banked items are not versioned in this way.

Lothlorien Gift Box Changes:
There is no longer a chance to receive First-age items.
There is no longer a chance to receive Tier 4 Runics.
The Heritage Runes have significantly increased in value.
The lowest value is now 75k.
The highest value is now 250k.
There is now a chance to receive Level 58 and Level 59 Second-age items (you can still get Level 60 Second-age items as well).
The odds have been tweaked, the most significant of which is that there's now a slightly higher chance of receiving a Second-age item, but a lower chance of that Second-age being Level 60 (due to the inclusion of Level 58 and 59 Second-age items).
The costs of the gift boxes have been significantly reduced: they now cost 15G 30S.
The descriptions of the gift boxes have been changed to more accurately reflect the potential rewards.
The gift boxes are no longer class restricted for those who mistakenly purchased the wrong box.
Please note that there will be no compensation for those who have already purchased a gift box: when you opened that gift box you had a chance to get a Level 60 First-age item.

Explanation of Changes:
The gift boxes have been changed from a high-risk / high-reward design to a more friendly middle-ground design. The high-end rewards have either been removed (First-age) or had their chances reduced (Level 60 Second-age), while the low-end rewards have either been removed (15k Heritage Rune, Tier 4 Runics) or increased (250k Heritage Runes are now available). Because the high-end rewards have been removed/reduced, the cost of the giftboxes has been reduced as well.

First Age Legendary Items

First Ages are now dropped via a barter system.Each raid now drops barter tokens that can be saved up to use to trade for the First Age item of your choice. Vile Maw, Strange Happenings, and Dar Narbugud will all drop multiple tokens. Go visit the barter traders at the Hythe docks to see all the possibilities.
Level 59 First Age's will cost 4 tokens
Level 60 First Age's will cost 6 tokens

Currently First Age Legendary items are Bind on Acquire on Bullroarer. This change will be reverted and will not go live when Book 8 ships.

It's the Little Things That Count

The impending war between the Light and the Dark has caused many of the vendors in the world to fear for the stability of their livelihood. In an effort to retain business the vendors have now learned to sell stackable items in quantities other than "one" and "a full stack" in order to better serve you! While you have the vendor UI open you can now buy single items by default, or use…
SHIFT to purchase a full stack,
ALT to purchase a quantity that you specify in a pop-up dialog
TAB to fill all stacks of the selected item type in your backpack.
