Fixes

• Fixed an error with the language expression that could occur on legacy versions (#4616) (Thanks @Matocolotoe)
• Improved error messages from the new Pattern Compiler (#4546, closes #4541)
• Fixed an issue where hex colors didn't parse where they should (#4529, closes #4527) (Thanks @Sorbon-CH)
• Fixed a parsing issue where unrelated errors would be mistakenly printed (#4530)
• Fixed an issue where the "no scripts found" error mistakenly displayed with a config file line (#4549)
• Fixed an issue where parsing could mistakenly fail with literals (#4242, closes #3465)
• Fixed a few issues with function parsing, notably issues with default values (#4244, closes #4049)
• Fixes to parsing, also fixing the "all armor stands" expression (#4260, closes #2370, #2723, #4239)
• Fixed an issue where the enchantment level expression could incorrectly remove enchantments (#4393, closes #4391)
• Fixed an issue with block comparisons (#4390, closes #4340)
• Fixed an issue with "type of" expression being used with items/blocks (#4405)
• Fixed an issue with looping blocks below y=0 (#4647, closes #4645)
• Improved the behavior of or in lists (#4545, closes #4543)

Please note that with this change, or lists will no longer always pick a set value, meaning in something like:

set {_x} to 10
set {_y} to {_x} or {_not-set-variable}

{_y} will be set to 10 or set to nothing (whereas it would always be set to 10 before)

• Fixed issues with the saturation expression (#4554, closes #4552)

Please note that this change removes the ability to use saturation as a default expression. This breaks scripts that do something like:

on hunger bar change:
    broadcast "%saturation%"

• The filter expression no longer accepts single values/expressions (#4395, fixes #4306)
• Added a config file option for player name regex (#4396, closes #4374)

This is useful for plugins like Geyser where some usernames are prefixed by a specific character.

• Allow variable strings to be converted (#4408, closes #1144, #1940, #4272)
• Added a converter for strings to worlds (#4408)
• Added default expression and time state support to the biome expression (#4539)
• Entity event values are now excluded from death events (#4540)

This change forces users to use attacker/victim to avoid confusion as to why they're not getting a message or why their code isn't erroring.

• Improved comparisons between slots and numbers (#4550, closes #4548)
• Re-added all to the indices expression (#4551, closes #4547)
• Added an expression to get the protocol version of a player (#4569) (Thanks @bilektugrul)

• Added an expression to get the hanging entity and remover in hanging break and place events (#4592, closes #4359, #892)
• EffectCommandEvent is now a Bukkit event, meaning plugins and addons can listen for it (#4532, closes #4360)
• Fixed an issue where some syntax elements were missing [the] prefixes (#4604)
• Fixed vector length reset when adding or setting pitch and yaw (#4626, closes #4610) (Thanks @sovdeeth)
• Improved the validation checks for hex codes (#4628)
• Added an error for when hooks are disabled after Skript has loaded (#4702)
• Added a player event value to the item drop event (#4615)
