[rasection="Wesnoth Formula Language update"]
The Wesnoth formula language used by $(...) substitution, the formula= key in standard unit filters, and a few other places has received some significant updates. The changlog has the full list, but some highlights are:
[list]
[*]New operators for string concatenation, ranges, and testing containment
[*]New string interpolation syntax
[*]Dot operator can access identifier-friendly string keys in maps
[*]Function definitions work outside FormulaAI and GUI2
[*]Many new functions for math and string manipulation
[*]Exponentiation operator is now right-associative (meaning 2^3^2 now produces 512 rather than 64)
[*]Dice operator is now synced
[*]Improved formula debugger
[/list]
The "fai" and "faiend" keywords are deprecated in favour of "wfl" and "wflend" respectively. This is part of a move to more clearly distinguish [wiki]Wesnoth Formula Language[/wiki], the language itself, from [wiki]FormulaAI[/wiki], which is just one use of the language in Wesnoth.
