3.4.0 (ST3 and ST4)

The version immediately before this is 3.2.0. There is no version 3.3.0

Support for fish 3.3:

• There were no relevant changes to the fish syntax in fish version 3.3

Support for fish 3.4:

• Add the alternate syntax for command substitution $(...) which works in double-quoted as well as unquoted strings (fish-shell/fish-shell#159, fish-shell/fish-shell#8059)
• Compatibility highlighter will draw attention to the deprecated use of & without a separator before or after it (fish-shell/fish-shell#7991)

Improvements:

• Allow the fish_directory setting to be a dictionary with per-platform values in addition to a simple string (thanks @eugenesvk!)
• Use meta.function-call.operator.control.{newline,semicolon,ampersand} to distinguish control operators

Renamed scopes:

• keyword.operator.control.{double-ampersand,double-bar} -> meta.function-call.operator.control.{double-ampersand,double-bar}
