There were numerous bug fixes and other enhancements to the server code. However, this list will only include features that are noticeable in-game.
Messages marked in bold are especially worth notice.
---------------------------------------------------------------------
Fix typo in region "portjoseph".
Fix player count reporting to the metaserver. It now excludes connections with not-yet-logged-in players and AFK/WIZ/BOT players.
Modified the way the "undead" flag is removed from the player when changing god. This fixes bug #1157459; now, the player should recover its initial race after leaving the Devourers for another god.
Fix bug #1528197, by making dragons prefer clawing over anything else as unarmed combat technique.
Forbids the use of reset on oneself's map while in a transport. This is a workaround for bug #1528172
Make the search for a friendly target for some spells also browse transports located in the square from which the spell was cast. This is a fix for bug #1528018.
Select op->facing instead of op->direction in process_events for players and monsters as the direction reference for the face to display. Fix for bug #1528182. (NOTE: your character no longer turns his/her back to you when idle)
Correct improper selection of the target of some spells, when the spell is cast on a transport. Hopefully definitively fixes bug #1528018.
In describe_item() correct capacity description of large (>1000 maxsp) Glowing Crystals
Prevents one to write a scroll with a spell he/she's denied from. Fix for bug #1530001 - "Inscription skill allows to cast denied spells"
Fix bug #1529969 (shop floor not working in random maps)
Fix bug #1526364 (stacking Royal Guards) (Note: when royal guards were summoned - multiple ones would appear stacked on top of each other; when you thought you were fighting one - you were actually fighting 3 or more, which made things harder then they should have been)
Tell player whether she's the transport's captain or not
Implement feature request #1528641 (consecrate should change face of altar)
Feature request #821645 (change password command)
Feature request #1465397 (improved feedback in character creation for existing names)
The default listen level is 10 - which means everyone logging in will have access to the chat channel.
Fixed incorrect behavior of the create missile spell, that couldn't find a proper archetype when a bow or a crossbow was wielded. This is a fix for bug #1532403.
Modified command_drop so it is less noisy about locked items when doing a "drop all" request. This is a fix for bug #1539121.
Modified command_take so it is less noisy about no_pick items when doing a "get all" request. This is a fix for bug #1539122.
Changed the comparison code between the weapon's name and the player's, so that a weapon created by "gro" cannot be used by "gros. This is a fix for bug #1539150.
Added a field in the map structure to store the timestamp of the last original map loading, and modified the Town Portal spell so that it now cannot lead to a map that was marked before a reset, after a reset. This is a fix for bug #1539155
Fixed the Burial Ground so the clues cannot be destroyed or removed. Added a couple of details on the gravestones to make them a little more, hum, alive
