## [v2018.07.01+1] `Jul 1 2018` `PATCH 1`
### Fixed
- Fixed a regression that made it impossible to invite guild members. (#2124, issue #2122)

## [v2018.07.01] `Jul 1 2018`
### Added
- Added/updated packets and message tables for clients from 2018-05-30 to 2018-06-12. (#2064)
- Added/updated a pair of enums (`cz_ui_types`, `zc_ui_types`) for the values used by packets 0xa68 and 0x0ae2, fixed compatibility with older clients. (part of #2064)
- Added the possibility for a plugin to abort the skill currently being cast by returning true from `skill_check_condition_castend_unknown()`. (#2076)
- Implemented Pet Evolution. This adds a new `Evolve` field to the Pet DB, and a generator script is provided, to automatically create entries from the pet evolution lua. (#2063)
- Implemented Pet Autofeeding. This adds a new `AutoFeed` field to the Pet DB, and can be completely disabled through the `enabe_pet_autofeed` flag in `feature.conf`. (#2063)
- Added the script command `setparam()`, the setter counterpart of `readparam()`, accepting an optional account id argument. (#2081)
- Updated maps database/mapcache with new maps (part of #2098)
- Added/updated packets and message tables for clients from 2018-06-20 to 2018-06-27. (#2095)
- Added new map/mapserver-change packets for the airship system. (part of #2095)
- Added new (unused) 'dns host' field in `char_send_map_info()`, compatible with clients newer than 2017-03-29. (part of #2095)
- Added an option to hide names in the script commands `unittalk()` and `npctalk()` (#1831, formerly #1571, issue #1523)

### Changed
- Updated README with more info about the development dependencies. (b57232ac29)
- Updated `instance_create()` when trying to create an already existing instance, to match the official behavior. (#1924, issue #1651)
- Removed the `RTLD_DEEPBIND` flag from the plugin-loading functions, for compatibility with asan in gcc-8. (#2079)
- Standardized the function call syntax in the script command documentation. (#2084)
- Changed the way pet eggs are handles in the inventory (they don't get deleted when hatched), for compatibility with the pet evolution system. (part of #2063)
- Extended the script command `readparam()` with the ability to receive an account id as optional argument, as an alternative to the character name. (#part of 2081)
- Updated the Private Airship map list to match the main kRO servers, and enabled the functionality on the main packetvers. (#2098)
- Updated pin code status packets for the 2018 clients. (part of #2095)
- Updated the authentication error packets in the map server to use the most recent version for the current packetver. (part of #2095)
- Updated the roulette packets for the 2018 clients. (part of #2095)

- Changed all the functions (where possible) to have static linking, in order to prevent incorrect symbols to be used by plugins, as a safer alternative to `RTLD_DEEPBIND`. Plugin authors are still advised to avoid naming their local symbols with the same name as non-static symbols exported by the code. (#2112)
- Prevented compilation of the non-memmgr memory management function wrappers when the memory manager is enabled. (part of #2112)

- Added support for 2017-10-25 - 2017-11-01 clients. (#1889)
- Added support to display NPCs with player classes, including equipment and styles (best with clients starting from 20170726). This extends `getunitdata()` and `setunitdata()` with support for `UDT_SEX`, `UDT_HAIRSTYLE`, `UDT_HAIRCOLOR`, `UDT_HEADBOTTOM`, `UDT_HEADMIDDLE`, `UDT_HEADTOP`, `UDT_CLOTHCOLOR`, `UDT_SHIELD`, `UDT_WEAPON`, `UDT_ROBE`, `UDT_BODY2`. (#1893)
- Added type constants for the `getiteminfo()` and `setiteminfo()` script commands. Existing third party code must be updated to use the new constants (see the pull request description and the command documentation for details). (#1902)
- Added global function `F_GetAmmoType()`, counterpart to `F_GetWeaponType()` for ammunitions. Both functions have now been updated to only check the subtype if the item type is correct (`IT_AMMO` and `IT_WEAPON` respectively). (part of #1902)

### Changed
- Applied script standardization to the Octopus Cave instance script. (#1882)
- Applied script standardization to the Ghost Palace instance script. (#1879)

- Applied script standardization to the Orc's Memory instance script. (#1872)
- Applied script standardization to the Sealed Shrine instance script. (#1873)

- Cleared some confusion between skill IDs and indexes through the codebase. Rewritten Skill DB accessors in a safer, more readable way. (part of #1896)

### Deprecated
- The use of numeric type constants with `getiteminfo()` and `setiteminfo()` is deprecated. For technical reasons, no deprecation notice is displayed. (part of #1902)

### Removed
- The `MAX_SKILL` constant has been removed, in favor of the more clear `MAX_SKILL_DB`, to be used in all places that use the compacted Skill DB array. For use with the non-compacted clientside Skill IDs, the `MAX_SKILL_ID` constant is still available. (part of #1896)

### Fixed
- Fixed compilation warnings when compiling with gcc-7. (#1887)
- Fixed the display flag for monsters labeled as `boss_monster` to be that of MVP monsters instead of miniboss monsters. (part of #1889)
- Fixed a subtle error in case `skill->unit_group_newid` overflows, causing certain skill unit entries to get stuck and never get deleted correctly. This can manifest itself with some monster spawns becoming immune to certain AoE spells having the `UF_NOOVERLAP` flag (Storm Gust, Lord of Vermillion, etc). (#1896)
- Implemented MATK support in the `getiteminfo()` and `setiteminfo()`. This functionality was previously advertised as availble in the command documentation, but was not implemented. (part of #1902)
- Restored View Sprite support in the `getiteminfo()` and `setiteminfo()`. This functionality was lost with #1828. (part of #1902, issue #1895)
- Reimplemented the global function `F_GetArmorType()` to reflect the fact that  `ITEMINFO_LOC` returns a bitmask. The function now handles multi-slot headgears and other uncommon cases better. (part of #1902)
- Corrected some incorrect data types passed to the SQL `StmtBind` functions, causing query errors and data loss. Said functions will now have a runtime assertion to ensure the right data type is passed. Third party code needs to be updated to reflect this stricter requirement. (#1901, issue #1531)
- Corrected some RODEX related queries in case `MAX_SLOTS` or `MAX_ITEM_OPTIONS` are set to custom values. (part of #1901)

## [v2017.10.22+1] `October 22 2017` `PATCH 1`
### Fixed
- Fixed a wrong null pointer check in `logmes()`, which caused the command to never log and instead print debug information.

## [v2017.10.22] `October 22 2017`
### Added
- Added the script command `getmapinfo()`, which allows to obtain misc information about a map. (#1852)
- Added an option to restrict party leader changes to characters on the same map. Controlled by the setting `party_change_leader_same_map` (defaults to true). (#1812)
- Added initial support (shuffle packets, obfuscation keys) for clients 2017-09-27, 2017-10-02, 2017-10-11, 2017-10-18. (#1859)
- Added the `noautoloot` mapflag, allowing to disable the `@autoloot` functionality on a map by map basis. (#1833)

### Changed
- Extended the script command `logmes()` with an option to log to the `atcommandlog` table. (#1843)
- Updated RoDEX, with support for packetver `20170419` and newer. (#1859)
- Updated Exp-related packets and handling functions to support values larger than 2 billions (as seen in packetver `20170830` and newer). (#1859)
- Changed the diagnostic message in `skill_init_unit_layout()` to report the skill ID instead of its index. (#1854)

### Fixed
- Corrected the Kafra dialog in case a Doram without the Summoner's Basic Skill attempts to open the Storage. (#1864)
- Changed the cell stack counting algorithm to ignore invisible NPCs, improving the Dancer Quest experience as well as other cases of hidden NPCs blocking off certain cells. (#1827)
- Improved the handling of the `cardfix` value to make it more resistant to overflows, especially in renewal mode. Simplified the related renewal/pre-renewal conditional code. (#1825)

### Other
- New versioning scheme and project changelogs/release notes (#1853)
