Changelog

• Devnet and testnet are now running updated validator and RPC builds.
• Unlimited fungible token rows are migrated into the big-fungible storage format, keeping balance, stake, supply, and burned-counter data on the representation expected by current token semantics.
• New token semantics reject malformed small-fungible states before they can move through token creation, transfer, mint, burn, stake, or unstake paths.
• BigInteger + parsing now matches the shared VM/runtime fixtures used by the validator and SDK test suites.
• RPC token-event reconstruction now treats token repair migrations as storage representation changes, not fake token movement.
• TokenInfo updates no longer appear as fresh TokenCreate events in reconstructed RPC event data.
• Testnet also receives the validator hardening already active on devnet, including stricter VM/runtime input handling and more reliable validator status responses.

• Devnet validators are now running the latest validator build.
• Bigint handling was tightened across JSON payloads, genesis data, and signed Int256 parsing, rejecting malformed inputs more consistently.
• NFT mint and import flows now require the referenced series rows to exist, keeping token-series state stricter during contract testing.
• VM schema and sanitizer lifetime handling was hardened for contract execution paths.
• Validator status responses are protected against stalled HTTP connections, and memory usage logging is clearer for operators.

• The Python SDK documentation now includes setup, RPC, keys and addresses, VM transactions, Carbon workflows, token deployment, NFT minting, schemas and metadata, fees and broadcasting, examples, and a complete API reference.
• The Rust SDK documentation now has the same full guide structure, including read-only RPC, offline transaction examples, Carbon token and NFT workflows, and reference pages for RPC models, VM transactions, and wire-format data.
• Smart contract docs now include Storage And Data Escrow, explaining how current contract storage growth is paid through transaction-level SOUL data escrow and maxData, not by staking SOUL to a contract address.
• The SDK area was reorganized so Python and Rust sit alongside the existing C#, Unity, TypeScript, and C++ sections in the GitBook navigation.
• Existing compiler, Link Client, Unity example, and SDK pages received navigation, formatting, and wording cleanup so the developer docs read more consistently.

• phantasma-sdk-py 2.0.2 is available on PyPI.
• phantasma-sdk 1.0.1 is available on crates.io.
• Both SDKs were rebuilt around the current Phantasma developer stack, including transaction building and signing, VM script helpers, JSON-RPC access, Ed25519 keys/signatures, and Carbon wire-format support.

• Devnet and testnet validators are now running the updated build.

• Validator failover handling was tightened for unavailable or stalled leaders.
