v0.4.0

0.4.0 (2026-11-04)

Changed

• Breaking: kest fmt keeps the brackets around a block that gives a value (|x| value) wherever it is an operand: before a call, a field or an index, after a unary operator, and inside a binary operator. It dropped them and wrote a different expression while answering 0: (|| 41 + 1)() came out as || 41 + 1(), a block giving a call, and (|| c + 1) * 2 as || c + 1 * 2; where that form was not stable, fmt refused the file as a fault in the formatter. None of these blocks compile (K0367), so no program that runs changes, but fmt now writes different bytes for a file holding one. A block in braces, and a block handed to a function as an argument, are written as before. (#227)

Fixed

• kest_held_begin and kest_held_call refuse an args of NULL with a count above nought, answering false and writing K0636 to errors with the door as the host named it ("step was handed 2 values and no address to find them at"). They copied count values from NULL and crashed the host. Values handed with an address are copied exactly as before. (#225)
