We present a change in version 1.3.0 of the evaluation process of boolean operators and and or in test expression of the if instruction and expression.

Consider the following if instruction:

if a and b then
 /* */
end

We present an improvement in the way assets data are accessed in version 1.3.0.

Problems​

Until this version, the only way to access an asset data was the field accessor operator of the form A[k].f, where A is the asset collection, k the asset key and f the asset field.

We present a new type of map called iterable_big_map, which has the scalability property of a big_map, and which can be iterated like a basic map.

This feature was suggested by Nomadic Labs. Thank you to Lucas Feli and Charles Delhinger for the algorithm.

Example​

Consider the following declaration of an iterable big map between a nat key and a bytes value:

variable ibm : iterable_big_map<nat, bytes> = []

We present the new instruction emit to emit an event, in a similar an event is emitted in languages like solidity.

This feature was suggested by Nomadic Labs.

An event is declared with the event keyword, similarly to a record:

event HighestBidIncreased {
  bidder : address;
  amount : tez
}
