v2021.01.11

Added

• Integrated the Renewal mob database with the correct DamageTakenRate value for MVPs that require it. Those MVPs have a green aura and only receive 10% of the damage dealt to them. (#2875)
• Added an enum for client action types. See enum action_type. (#2930)
• Added skill prerequisite checks before leveling up homunculus skills, allowing the definition of prerequisites for non-evolved or non-loyal homunculi, as it was previously limited to those. The check is disabled when the player_skillfree setting is enabled in the battle config. (#2807)
• Added constants for the mercenary_delete() script command as well as the mercenary->delete() function and documentation for the formerly undocumented values. See enum merc_delete_type and the script constants MERC_DELETE_*. (part of #2858, issue #2843)

Changed

• Cleaned up mob database from redundant MVPExp: 0 fields. (part of #2875)
• Updated packet CZ_REQUEST_ACTNPC to use a struct. (part of #2930)
• Changed the default mercenary delete type of the mercenary_delete() script command to be fired by the user (not updating loyalty). (#2843)

Fixed

• Fixed an issue that caused the Sign quest to lock up and become unfinishable for everyone when a player times out or logs out under certain conditions. (#2921)
• Fixed an exploit that allowed multiple people into the solo room of the Sign quest. (part of #2921)
• Fixed a failed assertion when using the MH_SUMMON_LEGION skill. (#2929)

Removed

• Removed the undocumented and meaningless return value of mercenary->delete(), now returning void. It was previously relying on the return value of two other functions, and ultimately always returning zero. (part of #2843)
