Changelog

All notable changes to this project will be documented in this file.

[0.2.1] - 2026-05-29

Catches up to TypeScript SDK 0.1.27. speed parameter now accepts a raw override dict in addition to the four preset names.

Added

  • SessionSpeedOption = Union[str, dict] — speed parameter type used by every writer/reader function that accepts a speed.
  • resolve_session_config(speed) — string|dict|None → always returns a fresh {max_rps, max_concurrency, max_concurrency_upload} dict. Missing dials in a dict override fall back to DEFAULT_SESSION_SPEED.

Changed

  • All writer/reader speed: str | None parameter type hints widened to SessionSpeedOption | None. String preset names still work; you can now also pass {"max_rps": 80, "max_concurrency_upload": 30}.
  • Internal helpers (_resolve_session_config, _resolve_upload_config) removed — resolve_session_config replaces both, exported from iqlabs.utils.

[0.2.0] - 2026-05-29

Catches up to TypeScript SDK 0.1.26. One-to-one parity verified for every contract, writer, reader, utils, and crypto export.

Added

  • v0.2 fee restructure: create_table_instruction now requires the new db_root_creator account, and writer.create_table auto-decodes it from the DbRoot state — caller signature unchanged.
  • New ix wrappers: set_root_table_creation_fee_instruction, clear_root_table_creation_fee_instruction, transfer_db_root_creator_instruction.
  • decode_table_meta now returns last_timestamp (for gateways).
  • utils re-exports: run_with_concurrency, SESSION_SPEED_PROFILES, DEFAULT_SESSION_SPEED, resolve_session_speed.
  • reader.collect_signatures for paged signature enumeration.
  • writer_utils.send_tx_with_retries for stable concurrent chunk uploads.
  • SESSION_SPEED_PROFILES entries now include max_concurrency_upload (1 / 5 / 50 / 100 for light/medium/heavy/extreme).

Changed

  • upload_session uses max_concurrency_upload and send_tx_with_retries for the chunk-fanout phase.
  • IDL refreshed to match mainnet program (v0.2 fee structure).

[0.1.2] - 2026-02-12

Fixed

  • Fixed Table and Connection account decoders to correctly handle optional fields
    • gate_mint field now properly decoded as Option<Pubkey> instead of required Pubkey
    • writers field in Table now properly decoded as Option<Vec<Pubkey>>
    • This fixes issues where tables created without gate_mint were incorrectly decoded

[0.1.1] - 2026-02-12

Fixed

  • Fixed send_tx function compatibility with solders >= 0.23
    • Updated Transaction creation to use Message.new_with_blockhash instead of deprecated Transaction.new_with_payer
    • Fixed recent_blockhash attribute error with newer solders versions
    • Fixed signature type handling in confirm_transaction
  • Improved compatibility with httpx >= 0.28.0

Changed

  • Transaction signing now properly handles both Keypair and WalletSigner types

[0.1.0] - 2026-01-03

Added

  • Initial release
  • Support for on-chain data storage
  • Database tables and connections
  • Code-in functionality
