Scans can now be limited to worlds (continents or instances). You can customize this for custom NPCs with an edit box next to the NPC's ID; Simply type the name of the world exactly, or select a continent name from the dropdown. If left blank, the scan will stay active no matter where you are.
Tables of rares in the Search configuration pane are now sortable by clicking their column headers.
Default options now only add tamable custom mobs like Arcturis and Skoll for hunters. Hold <span style="font-family: monospace">shift</span> while reverting to defaults to override this.
No longer shows an alert button for tamable NPCs while resting (in an inn or city), although you will still need to clear the cache.
Added all localized mob names for zhTW, and as many as I could find for zhCN and koKR.
Added an “<span style="font-family: monospace;">Unmute for alert sound</span>” setting to play the alert sound even if WoW is muted.
Added an “<span style="font-family: monospace;">Alert sound file</span>” dropdown to choose which sound to play for alerts. Additional sounds can be added using SharedMedia-type addons.
The alert border flash now only shows when you enable “<span style="font-family: monospace;">Screen Edge Flash</span>” in the Default UI's Display Interface Options panel.
Now continues searching for rares in 5-man dungeons. Raid dungeons, battlegrounds, and arenas will still disable scanning, however.
Achievements to kill rares now have their own lists in the options window.
Added slash commands to add and remove NPCs from the custom tracking list: “<span style="font-family: monospace;">/npcscan add <NpcID><Name></span>” and “<span style="font-family: monospace;">/npcscan remove <Name></span>”
You can now add tamable mobs to your search list and toggle them all using a “<span style="font-family: monospace;">Search for tamable NPCs</span>” setting.
Found alerts for tamable mobs will note that they are tamable and may be false alarms.
Added an option to suppress the “already cached” log-in alert.
Added Gondria to the default rare list, and updated some rares that are now tamable in 3.1.
