0.2.0 - 2025-12-01

Breaking Changes

• Refactor: Removed use_stored_data parameter from _calc_resulting_vote call in hive.py.

• Refactor: Converted Amount.tuple property to as_tuple() method.

• Refactor: Removed legacy HiveSigner integration and related dependencies.

• Refactor: Standardized API endpoint naming to use _api suffix throughout codebase.

• Refactor: Deprecated appbase utility functions.

Improvements

• Transaction: Increased default transaction expiration from 30 seconds to 300 seconds to better handle node clock skew and network latency.

Features

• Transaction: Added json_str parameter to multiple transaction operations.

• Node Management: Simplified NodeList to use PeakD beacon API with static fallback nodes.

• Performance: Improved blockchain tests with limited data collection and structure validation.

• Compatibility: Removed Python 2 compatibility code and modernized syntax.

• CLI: Added string time parsing support to account history methods.

Fixes

• Security: Fixed PasswordKey seed generation and PublicKey string methods.

• Security: Fixed cipher decoding in extract_memo_data.

• Reliability: Improved type safety and null handling across almost all core modules (Account, BlockChainInstance, Hive, etc.).

• Reliability: Fixed circular import in instance module.

• Reliability: Improved RPC retry logic and error handling for witness and node operations.

0.1.5 - 2025-11-04

• Feature: Added a --witness/-w flag to the hive-nectar rewards CLI that aggregates producer rewards into a PrettyTable, respecting the requested date window.

• Fix: Resolved KeyError and zero-output issues in the rewards CLI by iterating over all relevant operations, normalizing producer reward timestamps, and gracefully handling curation entries missing comment_permlink data.

• Tests: Extended CLI coverage to ensure the new witness mode runs without errors.

0.1.4b - 2025-10-12

• Refactor: Refactored Account’s vote‑pct calculation to correctly convert the desired token value to an Amount, introduce a safe ratio clamp (‑10 to 10) to avoid extreme values, and return 0 for zero‑vote scenarios; updated all discussion query fallbacks to use the condenser API and handle dict‑style responses, and tweaked tests to instantiate Account directly.

0.1.4b - 2025-09-19

• Feature: Added payout-based vote helpers on Comment :

  • Comment.to_zero(account, partial=100.0) computes the UI downvote percent to reduce a post’s pending payout to approximately zero (uses reward fund + median price + effective vesting shares; scales by the account’s downvoting power). Returns negative UI percent and broadcasts automatically (suppress via the blockchain instance’s no_broadcast).

  • Comment.to_token_value(account, hbd, partial=100.0) computes the UI upvote percent to contribute approximately the given HBD value. Returns positive UI percent and broadcasts automatically (suppress via no_broadcast).

• Fix: Corrected vote value math to align with the beem reference formula:

  • Restored get_hbd_per_rshares() to derive HBD/share as (reward_balance / recent_claims) * median_price(HBD/HIVE) .

  • Applied the missing / 100 scale factor from the sample when converting rshares to HBD-equivalent in payout-based helpers.

  • ActiveVotes.get_downvote_pct_to_zero() updated to use effective vesting shares and the account’s downvoting power; analytic path improved and payout-based path added via Comment.to_zero() .

  • vests_to_rshares() reverted to chain-accurate power computation via _calc_resulting_vote and dust-threshold handling.

  • rshares_to_vote_pct() updated to invert the chain power model consistently (taking max_vote_denom into account).

• Docs/Examples: Added examples/get_vote_pct_script.py showing how to compute both the downvote-to-zero percent and the upvote percent to reach a target HBD.

0.1.3 - 2025-09-18

• Test: Working on getting 100% test coverage

• Feature: Added some HAF features for things like reputation.

0.1.2 - 2025-09-17

• Fix: Replaced missing **kwargs in Blocks constructor.

0.1.1 - 2025-09-17

• Fix: Added support for only_ops and only_virtual_ops parameters in Blocks constructor.

0.1.0b - 2025-09-17

• Breaking Change: Killed everything that was not specifically HIVE related. If you used this for STEEM and / or Blurt, they are no longer supported.

• Fix: Corrected inverted fallback logic in chain detection to prefer HIVE over STEEM when blockchain_name is None.

• Fix: Restored backward compatibility for constructor parameters:

  • Vote.__init__: Added support for deprecated steem_instance and hive_instance kwargs with deprecation warnings.

  • ActiveVotes.__init__: Added support for deprecated steem_instance and hive_instance kwargs with deprecation warnings.

  • Witness.__init__: Added **kwargs with warnings for unexpected parameters.

  • Comment_options.__init__: Added fallback support for deprecated percent_steem_dollars parameter.

• Improvement: Removed deprecated websocket support from GrapheneRPC, now only supports HTTP/requests for better reliability and maintainability.

• Improvement: Simplified ecdsasig.py to use only cryptography library, removing complex conditional logic for different secp256k1 implementations. The tweak_add operation now raises NotImplementedError when called.

• Major Feature: Implemented pure Python secp256k1 elliptic curve operations for PublicKey.add() method, restoring compatibility with existing code that relies on key derivation. The implementation includes proper validation, error handling, and maintains the same API as before. All unit tests pass successfully.

• Fix: Fixed HiveSigner integration in TransactionBuilder:

  • Updated appendSigner() to restrict permissions to ‘posting’ when using HiveSigner

  • Fixed sign() method to properly call hivesigner.sign() and attach signatures instead of returning early

  • Fixed broadcast() method to use hivesigner.broadcast() when use_hs is True

  • Added proper error handling and fallbacks for non-HiveSigner flows

  • Fix: Fixed HiveSigner.broadcast() call in TransactionBuilder to pass operations list instead of full transaction JSON, and include username when available

• Fix: Fixed Claim_reward_balance operation serialization in nectarbase/operations.py:

  • Removed incorrect mutually-exclusive logic between reward_hive and reward_hbd

  • Updated to always serialize all four fields in canonical order: account, reward_hive, reward_hbd, reward_vests

  • Added proper zero-amount defaults (“0.000 HIVE”/“0.000 HBD”) for missing reward fields

  • Updated docstring to reflect correct behavior and field requirements

• Fix: Convert beneficiary weights from HIVE_100_PERCENT units (10000) to percentages in Comment.get_beneficiaries_pct() to ensure accurate outputs.

• Fix: Improve ECDSA signing to correctly handle prehashed messages and tighten signature canonicalization checks for better interoperability.

• Refactor: Reorder wallet lock verification to run after HiveSigner validation in TransactionBuilder, preventing premature lock errors for HiveSigner flows.

• Refactor: Replace implicit stdin default with an explicit blockchain selection in the CLI argument parser to avoid ambiguous behavior.

• Refactor: Update default Hive node configuration to use HTTPS endpoints instead of WSS.

• Feature: Add a pure-Python fallback for public key derivation when the ecdsa library is unavailable, improving portability.

0.0.11 - 2025-07-25

• Fixed handling of missing community field in comments (Comment) and improved weighted_score type check in node list ranking (NodeList).

0.0.10 - 2025-07-12

• Emergency hotfix: lower-case the UTC timestamp suffix during permlink generation (in derive_permlink) to resolve validation errors caused by the uppercase U.

0.0.9 - 2025-07-12

• Refactored nodelist logic:

  • update_nodes now reads authoritative node metadata from nectarflower account json_metadata only.

  • Uses weighted_score directly for ranking and zeroes scores for nodes missing from the report.

  • Dynamically adds new nodes from the report and failing list, ensuring completeness.

  • Removed unused fall-back paths and cleaned up internal code.
