Reasoning why this is part of the core and not a separate addon:
The impact of this function is extremely lightweight when (almost) no
aliases are defined so someone who isn't using this should not have a
worse experience.
Additionally including it in the core (similarly to the discounts,
taxes and restrictions) promotes it's availability while not massively
increasing the maintainability.
As for the OddItem removal:
That plugin hasn't been developed for over 7 years and such unique
plugin support should really be added via separate addon using the
events system which, with the new ItemStringQueryEvent, now actually
supports doing that from an external plugin.
If someone really managed to run their own private fork of OddItem for
all those years then they should be able to also provide such a simple
addon.
Message configs are now selected based on the client's language (can be
toggled in the config) and will use MineDown formatting to allow
display of component messages as well as usage of RGB colors in 1.16.
If found the legacy local.yml will be used instead of the per-language
files. Move your local.yml to the correct lang config to if you want to
use the per-client language option.
Version was also changed to 3.11 due to the many internal changes that
have accumulated over time
This is especially obvious for books where all the text will have color codes after dumping and loading them from the database. In order to be able to still compare to them we will load the item the item and then dump it again if it doesn't match the original one.
This is due to a bug in CraftBukkit not properly supporting localised/translatable display names when serialising item meta.
This also adds/improves the message when no valid item ID could be generated.
This is necessary due to the extended length of some material names in 1.13 as they directly include the variation into the material where previously only the data value was used. (E.g. BLACK_STAINED_GLASS_PANE) By removing the spaces and using uppercase characters to separate parts the string stays both readable to the user and parseable by the plugin. It should also be backwards compatible with the old format. (At least with 1.13 material names)
This uses hardcoded widths for the main characters used in Minecraft and might not be precise for some characters but better than the previous 15 char hard limit.
