[anton-trunov]

The Tact team has just release Tact v1.3.0 on NPM.

The full CHANGELOG for Tact v1.3.0 can be found here: https://github.com/tact-lang/tact/blob/main/CHANGELOG.md#130---2024-05-03

And here are a summary of editor/IDE-relevant Tact features.

New or fixed syntax

• Fixed precedence levels for bitwise operators, equality and comparisons. Now the precedence levels match common languages like JS/TS.
• Support for string escape sequences: \\, \", \n, \r, \t, \v, \b, \f, \u{0} through \u{FFFFFF}, \u0000 through \uFFFF, \x00 through \xFF.
• Allow chaining method calls with !!, for instance, map.asCell()!!.hash() is grammatically correct now.
• Trailing commas are allowed in struct instantiations, initOf arguments, init() parameters, inherited traits via with, function arguments and parameters.
• Struct fields punning, i.e. {foo, bar} is syntactic sugar for { foo: foo, bar: bar }.
• Inherited trait lists now must be non-empty if with is used.
• Bitwise XOR (^) operator.
• The implicit empty init function is now present by default in the contract if not declared.
• try {...} and try {...} catch {...} statements.
• foreach loop for the Map type: foreach (k, v in map) {...}.

New stdlib functions

• pow2, log2 and log math functions in @stdlib/math.
• Reserve mode constants in @stdlib/reserve, namely ReserveExact, ReserveAllExcept, ReserveAtMost, ReserveAddOriginalBalance, ReserveInvertSign, ReserveBounceIfActionFail.

New methods

• The concat non-modifying StringBuilder's extension function for chained string concatenations: foo.concat(bar).concat(baz).
• The toString extension function for Address type: addr.toString.
• The isEmpty and del extension functions for the Map type: map.isEmpty, map.del(key).
