Avian Core v5.0.0-rc2 "Smaug" Release Notes
Avian Core v5.0.0-rc2 is the second release candidate for the upcoming v5.0.0 major release. It focuses on stability, correctness, mining and RPC improvements, and fixes discovered during rc1 testing.
Highlights
Stability and correctness
- Fixed wallet locking in the rewards RPC
- Fixed missing mempool lock in asset validation
- Fixed a crash in GetTarget for certain low-difficulty MinotaurX blocks
- Made X16RT and MinotaurX hashing compiler-safe and deterministic
Asset and wallet fixes
- Enforced P2PKH-only addresses for asset operations and validation
- Added clearer bech32 error messaging for asset actions
- Fixed asset dropdown behavior on first open
- Mask asset name and quantity in privacy mode
- Fixed UnitValueFromAmount display and added test coverage
RPC and mining improvements
- Added powalgo option to generate RPCs
- Exposed per-algo difficulty in getchainstates and getmininginfo
- Removed leading newline from index RPC help output
- Updated minimum chain work and assumevalid
Notes
This release continues the v5 migration onto the Bitcoin Core 30.2 codebase while tightening Avian-specific behavior, especially around assets and mining.
Important: asset operations remain legacy P2PKH-only in rc2. Bech32 addresses are not accepted for asset creation or transfer.
As with rc1, more testing is encouraged before final release.
