4.5.1 release -- server-side changes since 4.5.0 (including those already mentioned):
-Halls of Mandos is now a "classic" (basic) ironman dungeon, no towns or anything.
-Death Fate dungeon is now a death trap, because you cannot leave it.
-A potential polymorphing bug was fixed.
-Many mimic powers' mana cost and fail rate have been reduced.
-Mimic powers now have a minimum fail chance of 1% (no change) and a maximum fail chance of 99% (new).
-Spell animation colours and monster flicker colours have been made consistent and improved. As a result of this, a few monsters flicker in a somewhat different manner now, most notably Death Drake, Bronze/Gold Dragonrider, Sky Drake, Blade Angels.
-Level 99 characters are unaffected by exp-draining attacks.
-Ent, Maia, Dark-Elf, Vampire lore have been added/fixed/improved.
-Vampires consume less and less food with higher character level, starting at level 40. They consume minimal food if they attain winner status.
-Some error messages on failed login attempts have been improved.
-Ufthak and Shagrat are now restricted to Cirith Ungol dungeon to fit the lore.
-Precedence when writing private chat messages is now character name > account name > party name.
-Priest character creation STR/DEX recommendations were removed because they were usually unreachable.
-Rods/wands of polymorphing can now be targetted at oneself.
-Bolt spells can now be targetted at a specific grid, and will affect the floor/items on it if there is no hostile target there.
-All beam spells now affect floor/items too.
-Various animals got a missing ANIMAL flag added, so they are correctly treated as animals by the game (ESP, movement).
-Self-knowledge now correctly displays if a character doesn't require food.
-A bug introduced in 4.5.0 regarding spell/breath splash damage not correctly decreasing over radius has been fixed.
-Trap of Lose Memories has been enabled. It drains a bit experience, as well as INT and WIS and causes confusion.
-Runes (runecraft) can no longer be created on floor grids in towns.
-Mithril Ancile item now weighs 10.0 lbs instead of 12.0 lbs.
-The initial cost of spell Phase Door is now 2 mana instead of 1 mana.
-If there are multiple best (closest) targets, auto-targetting will now prefer awake ones over asleep ones.
-Increased the minimum/maximum amount of items dropped by The Shadow of Dol Guldur.
-HARD_STEAL and VHARD_STEAL store flags have been toned down a bit.
-Book stores now offer up to 6 pages of items instead of 4.
-Bolt/Arrow/Catapult trap kits are possibly dropped with enchantments and can correctly be enchanted now.
-Changing preferred immunity (mimicry-users) will also change the immunity you are currently gaining from your form accordinlgy, if possible. So there is no more need for re-polymorphing into the same form to make the chosen immunity apply.
-Fixed a glitch where !X feature would take the level of the item that needs to be identified to determine fail rate for activating rod/staff of identify, rather than the rod/staff's level.
-The Stone of Lore and the Mage Staff 'Eriril' can now be used with !X inscription for easy ID.
-The Iron Helm of Knowledge now hurts sanity again instead of hit points, but the damage has been toned down.
-Slow poison effects actually slow poison again, in the traditional way.
-Holy Curing spell 'Curing' has been split up into 'Curing' and 'Restoration'.
-Nature spell 'Recovery' has been tweaked a bit.
-Starter books a la 'Beginner Cantrips' have been added for priests and shamans.
-A slash command has been added to allow you to convert a character into a slot-exclusive (PvP or IDDC) character: /convertexclusive. This is not reversible, so use with care.
Ironman Deep Dive Challenge:
-Unique monsters can now spawn in IDDC even if they already exist elsewhere in the world.
-Players cannot log out, wait for the level to reset, then log in again to "farm" it. (Floor will turn 'stale'.)
-Monsters will no longer spawn 'live' on a level. That means once a level is cleared of all monsters, it is and stays perfectly safe (except if someone uses a summon monster scroll or some such..).
-Items of value below 15000 gold (internal, varies for actual player characters) that are enchanted _in town_ with _stolen_ enchantment scrolls, will receive a 100% off discount to prevent easy money cheezing.
-'slot-exclusive' IDDC characters now start with 300 extra gold right away, and are unable to gain any gold from townies instead.
-Quests attained while inside the IDDC require a lower number of monsters to be killed than usual.
-There is a flat 20% exp bonus in the IDDC now, which stacks with the usual Ironman exp bonus.
-There is now a slight, progressive +LUCK bonus in IDDC, starting after Menegroth (the first town at dungeon level 40).
-All weapon/armour offered by stores in dungeon towns is now 'good', which means the items are enchanted and have an increased chance to turn out having ego powers.
-A bug in item ownership on characters that withdraw from IDDC has been fixed.
-Players can no longer accidentally get recalled by other players or effects while in the IDDC. The only place where recall spells work on other players is now the final floor of the IDDC.
-If players missing Sauron enter a floor where Morgoth is, he will teleport out and summon Sauron in his stead.
-Characters that have already beaten Morgoth are actually able to enter floors with Morgoth on them (spawned by other players who still haven't killed him) in the IDDC.
