sc 0.66.0, chain 0.23.0, sdk 0.16.0, scenario-format 0.26.1

• Memory and thread safety:
  • Managed type memory management: proper Drop implementations for managed types:
    • ManagedBuffer, BigInt, BigFloat, ManagedVec, and ManagedMap now call their VM-side destructor when dropped;
    • Fixed memory leaks and double-drop issues previously present in ManagedVec and ManagedBuffer;
    • ManagedVecItem derive macro now generates requires_drop correctly;
    • ManagedVec slice out-of-bounds fix;
    • MultiValueEncoded::to_arg_buffer fix;
    • Memory benchmarks added for managed types.
  • Thread safety:
    • DebugHandle and StaticApiHandle are now explicitly !Send;
    • All managed types implement !Send + !Sync, with tests.
• Mathematical library additions:
  • nth_root for BigUint;
  • linear_interpolation and weighted_average functions;
  • ManagedDecimal improvements:
    • exp_approx: exponential approximation function;
    • compounded_interest and compounded_interest_factor methods;
    • mul / div with half-up rounding mode;
    • Fixed into_raw_units / as_raw_units conversion;
    • nth_root support;
    • Backwards-compatibility fixes.
  • SaturatingSub / SaturatingSubAssign for BigUint.
  • BigUint::from_str (implements FromStr / parse());
• sc-meta new features, updates and fixes:
  • sc-meta transaction CLI (sc-meta tx): a new command-line tool for composing and broadcasting transactions directly from the terminal:
    • sc-meta tx deploy - deploy a contract;
    • sc-meta tx call - call a contract endpoint;
    • sc-meta tx query - query a contract (no gas);
    • sc-meta tx sign - sign a transaction offline;
    • sc-meta tx upgrade - upgrade a deployed contract;
    • --payments / --token-transfers flags for specifying ESDT payments;
    • --wait-result flag (requires --send);
    • --code-metadata args refactor.
  • sc-meta reproducible-build - new tooling for building and verifying contracts reproducibly:
    • Docker-based local build;
    • sc-meta all download with --overwrite flag;
    • sc-meta all publish / unpublish with polling and max-attempt logic;
    • Source pack/unpack (zip) with test & refactor;
    • artifacts.json generation and code hash verification;
    • repro-build init-config for project configuration toml;
    • repro-build release-notes CLI;
    • Integration test and CI support.
  • sc-meta data CLI: new subcommand for managing contract data/storage, for scripts.
  • Wallet improvements:
    • sc-meta wallet new hides password from console (uses rpassword);
    • sc-meta wallet test-wallet CLI command.
  • Other improvements:
    • sc-meta new --force flag: overwrite an existing template directory;
    • sc-meta new --overwrite bugfix;
    • sc-meta install wasm32 --toolchain <toolchain> CLI flag;
    • sc-meta install debugger on Windows, duplicate-protection, configures rust-analyzer.debug.engine;
    • sc-meta install all Windows fix;
    • sc-meta all codehash with fallback;
    • Detect duplicate contract names;
    • sc-meta rust version displayed in full;
    • CARGO_NET_GIT_FETCH_WITH_CLI env flag propagated through contract builds.
• Explorer URLs are displayed after transactions and for new contracts in interactor and sc-meta tx CLI.
• Rust VM gas schedule updates:
  • Gas schedule v9+ updates;
  • Fixed gas accounting for conversions, more hooks, and ManagedMap operations;
  • Overflow check added in multiply-gas helper;
  • wasmer-prod: fix for missing breakpoint after early exit / out-of-gas.
• Chain core additions:
  • Standard code hash function added to multiversx-chain-core;
  • VM code hash hook;
  • Basic crypto functions consolidated in chain core;
  • Deploy address computation impls centralized.
  • Bech32Address improvements:
    • try_from_bech32_string constructor with explicit error;
    • FromStr implementation;
    • Better error on empty string input.
• SDK improvements:
  • Interactor gas price support;
  • Refactoring: REST API types and naming updated to match the Go SDK implementation;
  • Wallet::from_pem_file accepts any AsRef<Path>;
  • Wallet methods now take AsRef<Path> generically.
• ManagedByteArray now implements SCDisplay and SCBinary.
• Dependency upgrades.
