## [v0.23.0] ### Added - [#259](#259) Adds a new upgradability library, including associated tests and documentation. - [#265](#265) Adds the `SetMetadataEvent` and emits `SetMetadataEvent` when the `_set_metadata()` function is called. - [#270](#270) Adds `OrdEq` functionality to Signed Integers. - [#272](#272) Adds the `TryFrom` implementation from signed integers to unsigned integers. ### Changed - [#265](#265) Enables the metadata events now that the Rust SDK supports wrapped heap types. - [#269](#269) Hashes the string "admin" and with the bits of an Identity when creating a storage slot to storage an admin in the Admin Library. - [#276](#276) Prepares for v0.23.0 release. - [#278](#278) Deprecates the Fixed Point number library. ### Fixed - [#258](#258) Fixes incorrect instructions on how to run tests in README and docs hub. - [#262](#262) Fixes incorrect ordering comparison for IFP64, IFP128 and IFP256. - [#263](#263) Fixes `I256`'s returned bits. - [#263](#263) Fixes `I128` and `I256`'s zero or "indent" value. - [#268](#268) Fixes subtraction involving negative numbers for `I8`, `I16`, `I32`, `I64`, `I128`, and `I256`. - [#272](#272) Fixes `From` implementations for Signed Integers with `TryFrom`. - [#273](#273) Fixes negative from implementations for Signed Integers. - [#274](#274) Fixes the `swap_configurables()` function to correctly handle the case where the bytecode is too large to fit in the buffer. - [#275](#275) Fixes an infinite loop in the Bytecode root library's `_compute_bytecode_root()` function. #### Breaking - [#263](#263) Removes the `TwosComplement` trait in favor of `WrappingNeg`. The following demonstrates the breaking change. While this example code uses the `I8` type, the same logic may be applied to the `I16`, `I32`, `I64`, `I128`, and `I256` types. Before: ```sway let my_i8 = i8::zero(); let twos_complement = my_i8.twos_complement(); ``` After: ```sway let my_i8 = i8::zero(); let wrapping_neg = my_i8.wrapping_neg(); ``` - [#272](#272) The `From` implementation for all signed integers to their respective unsigned integer has been removed. The `TryFrom` implementation has been added in its place. Before: ```sway let my_i8: I8 = I8::from(1u8); ``` After: ```sway let my_i8: I8 = I8::try_from(1u8).unwrap(); ``` - [#273](#273) The `neg_from` implementation for all signed integers has been removed. The `neg_try_from()` implementation has been added in its place. The following demonstrates the breaking change. While this example code uses the `I8` type, the same logic may be applied to the `I16`, `I32`, `I64`, `I128`, and `I256` types. Before: ```sway let my_negative_i8: I8 = I8::neg_from(1u8); ``` After: ```sway let my_negative_i8: I8 = I8::neg_try_from(1u8).unwrap(); ``` - [#278](#278) Deprecates the Fixed Point number library. The Fixed Point number library is no longer available. --------- Co-authored-by: K1-R1 <[email protected]> Co-authored-by: SwayStar123 <[email protected]>
