@ -3,6 +3,7 @@ EQEMu Changelog (Started on Sept 24, 2003 15:50)
== 02/06/2015 ==
Uleat: Updated returns for Inventory and ItemInst const iterators. (const == const)
Uleat: Replaced 'iter_inst' and 'iter_contents' typedefs with their stl definitions
Uleat: Removed 'limbo' from the 'HasItem' series of checks - including lore checks. The client excludes this range and it causes issues when performing item searches - dupe lore checks were added to account for this.
== 02/03/2015 ==
Trevius: Crashfix for TempName() when numbers are passed at the end of the name.
