❓Mandatory Upgrade?

• This upgrade is optional, but recommended.
• The current minimum supported release is v2.1.1.1

⏫ Upgrade Steps

• Backup your wallet.
• Download the appropriate file below for your OS (download links will appear once builds are finished).
• Replace your current neblio-Qt (.exe, .app, etc) with the one you downloaded.
• Restart the wallet using the new file you just downloaded.
• This release requires a QuickSync and rescan to update the blockchain database, let this process complete.

💥 Known Issues

• #259 neblio-Qt v3.0 does not fully support macOS Dark Mode. Disable Dark Mode in macOS System Preferences > General as a workaround

🎉 New Features

• Brand new design to match Neblio's updated branding!
• Add NTP1 Issuance Metadata to all applicable RPC outputs
• Added RPC command to export blockchain bootstrap
• Added dialog to add metadata to NTP1 transactions
• Added metadata option to createrawntp1transcation RPC command
• Added NTP1 Transaction Metadata to all applicable RPC outputs
• NTP1 token issuance dialog added to neblio-Qt, including issuance metadata
• Added options to multiple RPC commands to ignore NTP1 data to avoid reliance on the database being fully synced.
• Brand new release pipeline automatically monitors builds and posts them along with file hashes to GitHub
• Move from TravisCI to GitHub Actions for CI/CD
• Added one-click metadata encryption that securely encrypts NTP1 transaction metadata stored on-chain
• Added automatic NTP1 metadata decryption for wallets that include either the sending or receiving address
• Added option to encrypt metadata to RPC commands used for sending NTP1 tokens

🐛 Bug Fixes

• Fix potential QuickSync crash
• Fix bug that could cause a crash if malformed transaction is received
• Fix several JSON parsing bugs
• Fix potential crash that could occur if a transaction in the NTP1 cache does not exist
• Fix resync button to not be the default button in the options menu, which could lead to accidental resyncs
• Replace objs_msgSend() calls with native objc syntax
• Fix a bug that prevented macOS builds from downloading files using modern HTTPS standards
• Fix bug that allowed sending of NTP1 tokens to vouts > 31
• Fix a bug that could cause the wrong DB version to be downloaded during QuickSync
• Download QuickSync files to temporarily location. Move them to final location after successful download. Fixes bug that could cause a crash due to partly downloaded files.
• Fix incorrect RPC help text for getntp1balance & getntp1balances

🧰 Improvements

• Improve QuickSync reliability, especially on platforms such as Raspberry Pi
• Wallet will delete database and attempt QuickSync if database corruption is detected
• Wallet rescans are automatic after resyncs
• Optimize Block Index loading
• Added dynamic number of confirmations refresh rate to improve Qt responsiveness with huge wallet.dat files
• Improved compatibility with newer boost versions
• Completely remove all communication with Neblio API servers
• Enable timestamps in logs by default
• Improve modularity of entire codebase
• Moved all builds to OpenSSL 1.1.1
• Added docker image builds to CI/CD pipeline
• Build all macOS binaries using dependencies compiled for High Sierra (10.13) to ensure all builds are compatible with 10.13+
• Instead of downloading test data in-test, download compressed test data and extract it before tests are run, for faster testing
• Increase the maximum number of QuickSync attempts from 3 to 10, mainly useful for Raspberry Pi

⚙️ Other Changes

• Multithreading Enhancements and Fixes
• Allow decoding of transactions that do not exist in the database (RPC)
• Upgraded lmdb
• Allow the exporting of the blockchain with orphan block included (for debugging)
• Remove NTP1 cache when clearing blockchain database
• Removed Windows x86_64 builds from CI/CD pipeline
• Updated checkpoints
• Updated README
• Additional improvements and bug fixes
