Summary

Git Hash: e9a789189425bb70e7bf6bf0efa1dfa4a3e180f9
Compressed WASM Hash: 513bd326c827881278810c09327573a95aac84976a9a97c769847179223ffc27
Target Canister: uf6dk-hyaaa-aaaaq-qaaaq-cai

Features

  • The pricing has been updated in accordance with the new price function of HTTPS outcalls. In short, the number of cycles that need to be attached and the number of cycles charged have been reduced by a factor of 10!
  • The exchange rate canister now supports variable decimals. That is, the decimals field in the returned exchange rate metadata may deviate from the default value 9 to represent very small or large exchange rates.
  • Since all rates are represented as integers, the standard deviation in the metadata is now computed using an integer square-root function to minimize the use of floating-point operations.
  • The exchange rate canister now supports the upcoming dfx deps feature, which will make it possible to easily install canisters locally.
  • Several new end-to-end tests have been added to test the canister’s behavior in various scenarios.
