v2.82.0

What's Changed

This release adds string support for pending airdrop transactions, migrates to ethers v6 to eliminate known security vulnerabilities, updates key dependencies, and fixes a bug in node update transactions.

Enhancements

• String support for PendingAirdropId: The PendingAirdropId constructor and setter methods (setSenderId, setReceiverId, setTokenId, setNftId) now accept string inputs in addition to object instances. Strings are converted internally using fromString(). #3844

  Usage Example:

  const airdropId = new PendingAirdropId({
      senderId: "0.0.1234",
      receiverId: "0.0.5678",
      tokenId: "0.0.9012",
  });
  
  // Or using setters
  airdropId.setSenderId("0.0.1234");
  airdropId.setReceiverId("0.0.5678");

• Migration to ethers v6: Ethers v5 contained transitive dependencies (e.g. elliptic) with known security vulnerabilities that would not be fixed upstream. Migrating to ethers v6 resolves these entirely. #3870

Bug Fixes

• NodeUpdateTransaction description clearing: Fixed a bug where executing a NodeUpdateTransaction without explicitly setting the description field would inadvertently clear the node's existing description. #3889

Dependency Changes

• Upgraded bignumber.js from 9.1.1 to 10.0.2. #3807
• Migrated ethers from v5 to v6. #3870
• Upgraded typescript from 5.7.2 to 5.9.3 (dev dependency). #3871
• Upgraded @types/node from 24.0.8 to 25.5.0 (dev dependency). #3871

Full Changelog: v2.81.0...v2.82.0

v2.81.0

This release includes a fix for inconsistent handling of multiple transaction bodies within the SDK. The update ensures transactions are built and processed consistently, improving reliability when serializing and verifying transactions.

Bug Fixes

• Multiple Transaction Bodies Inconsistency: Fixed an issue where transactions could contain inconsistent or mismatched transaction bodies during processing or serialization. The SDK now ensures a single consistent transaction body is used throughout the transaction lifecycle, preventing unexpected validation or verification errors. #3832

v2.80.0

What's Changed

This release focuses on improving correctness and stability in time handling and node health management, addressing edge cases that could lead to incorrect date decoding and excessive node backoff under high concurrency.

Bug Fixes

• 64-bit Timestamp Overflow: Fixed an issue where validStart and expirationTime (Unix seconds represented as 64-bit values) were incorrectly converted using Long.toInt(). For timestamps greater than 2^32−1 seconds (e.g., year 2125), this caused overflow and incorrect decoding (e.g., decoding as 1988). ExchangeRate and ExpirationTime now correctly preserve 64-bit values. #3641

• Node Health Backoff Race Condition: Fixed a race condition in node health handling where concurrent failures could repeatedly increase backoff and mark a node unhealthy for an excessive duration. Backoff is now only increased when the node is healthy, preventing runaway backoff under high concurrency. #3647
