Version 2.4.0

ABI v2.4 specification implemented
Param in fields section extended with init: boolean
ref(T) – new type added
Default values for parameter types:
- int<N> – N zero bits.
- uint<N> – N zero bits.
- varint<N>/varuint<N> – x zero bits, where x = [log2(N)].
- bool – equivalent to int<N>, where N = 1.
- tuple(T1, T2, ..., Tn) – default values for each type, i.e. D(tuple(T1, T2, ..., Tn)) = tuple(D(T1), D(T2), ..., D(Tn)), where D is defined as a function that takes ABI type and returns the corresponding default value.
- map(K,V) – 1 zero bit, i.e. b{0}.
- cell – reference to an empty cell, i.e. ^EmptyCell.
- address – addr_none$00 constructor, i.e. 2 zero bits.
- bytes – reference to an empty cell, i.e. ^EmptyCell.
- string – reference to an empty cell, i.e. ^EmptyCell.
- optional(T) – 1 zero bit, i.e. b{0}.
- T[] – x{00000000} b{0}, i.e. 33 zero bits.
- T[k] – encoded as an array with k default values of type T
- ref(T) – reference to a cell, cell is encoded as the default value of type T.

data section in ABI JSON is removed.
fixedbytes type serialization changed. Now it is limited to 127 bytes and serialized into cell
body instead of chained cells in current cell reference
