Chia-blockchain

Added

- Farmers rejoice: today's release integrates two plotters in broad use in the Chia community: Bladebit, created by harold-b, and Madmax, created by madMAx43v3r. Both of these plotters bring significant improvements in plotting time. More plotting info [here](https://github.com/Chia-Network/chia-blockchain/wiki/Alternative--Plotters).
- This release also includes several important performance improvements as a result of last weekends "Dust Storm", with two goals in mind: make sure everyone can farm at all times, and improve how many transactions per second each node can accept, especially for low-end hardware. Please know that these optimizations are only the first wave in a series of many over the next few releases to help address this going forward. While the changes we have implemented in this update may not necessarily solve for _every_ possible congestion scenario, they should go a long way towards helping low-end systems perform closer to expectations if this happens again.
- Performance improvements for nodes to support higher transaction volumes, especially for low powered devices like RaspBerry Pi. Full details at [9050](https://github.com/Chia-Network/chia-blockchain/pull/9050).
- Improved multi-core usage through process pools.
- Prioritized block validation.
- Added transaction queues for more efficient handling of incoming transactions.
- Increased BLS pairing cache.
- Integrated the Bladebit plotter to CLI and GUI. Thanks harold-b for all your hard work on this, and welcome again to the Chia Network team!
- Added the Madmax plotter to CLI and GUI. Thanks madMAx43v3r for your support!
- Added option to configure your node to testnet using to `chia init --testnet`.

Changed

- Improved the wallet GUI's startup loading time by loading the default private key's fingerprint.
- Upgraded from clvm_rs 0.1.14 to 0.1.15.

Fixed

- Minor verbiage and syntax changes in CLI and GUI.
- Partial version to fix launcher name definition.
- Fix harvester plot loading perfomance issues.
- Fixed a packaging failure when passphrase is being used. Thanks ForkFarmer for reporting this defect.
- Fixed launcher name definition, which resolved an issue for some users in which wallet-node couldn't sync.
- Fixed a bug in the GUI that prevented some users from switching their plotNFT.

Known Issues

- PlotNFT transactions via CLI (e.g. `chia plotnft join`) now accept a fee parameter, but it is not yet operable.

We have some great improvements in this release: We launched our migration of keys to a common encrypted keyring.yaml file, and we secure this with an optional passphrase in both GUI and CLI. We've added a passphrase hint in case you forget your passphrase. More info on our [wiki](https://github.com/Chia-Network/chia-blockchain/wiki/Passphrase-Protected-Chia-Keys-and-Key-Storage-Migration). We also launched a new Chialisp compiler in clvm_tools_rs which substantially improves compile time for Chialisp developers. We also addressed a widely reported issue in which a system failure, such as a power outage, would require some farmers to sync their full node from zero. This release also includes several other improvements and fixes.

Added

- Added support for keyring migration from keychain, and the addition of passphrase support. Learn more at our [wiki](https://github.com/Chia-Network/chia-blockchain/wiki/Passphrase-Protected-Chia-Keys-and-Key-Storage-Migration).
- Enabled experimental use of a new Chialisp compiler in clvm_tools_rs in chia-blockchain, which is off by default, and substantially improves compile time.
- Added Windows PowerShell scripts to support installation from source.
- Added a test to check that we don't reorg subslots unless there is a new peak.
- Added harvester info to farmer logging.
- Add 'points found 24h' to CLI reporting.
- Added an alternative to pkm_pairs_for_conditions_dict() which is a bit more straightforward and returns the public keys and messages in the forms we need them to validate them.
- Added ability to see unopenable plots at the end of plots check.
- Added Program.at utility function.

Changed

- Truncate points\_[found,acknowledged]\_24h to 24 hours at each signage point.
- Improved reliability of test_farmer_harvester_rpc.py, by increasing the interval between harvester checks, which should avoid spamming logs with excessive plot refreshing and cache updates.
- Thanks cross for change that allows using IPv6 address in config.yaml for remote harvesters and other chia services.
- Change to stop creating unused indexes in block_records and full_blocks tables.
- Removed unnecessary index in CoinStore & add additional benchmarks.
- Changed db_sync setting to default to FULL. In a prior release, this setting caused some users to have to resync their full node from zero if the node went offline, such as in a power outage. Users can change this to OFF in config.yaml.
- Updated the coin_store benchmark to enable synchronous mode when talking to the DB, since that's the default now, and improves the output a bit.
- Updated the old comment on chia/util/streamable.py with newer developer documentation.
- Minor GUI changes based on community feedback.
- Thanks jack60612 for your help in improving our GUI code, including upgrading to electron 13, migration to electron remote, updating the latest dependencies, and more.

Fixed

- Corrected a super-linter name typo to GitHub
- Thanks sharjeelaziz for correcting our typo in your name. Our apologies for the error!
- In macOS builds, changed the export value of NOTARIZE to fix some build failures.
- Fix log output for duplicated plots.
- Removed a flaky mtime check for plots that resolved an issue where file_path.stat() shows multiple copies of plots and slows performance of the farmer. Thanks timporter for the assist on this one.
- Thanks jcteng for fixing a bug on the Chia DID wallet that showed 'mojo:'' instead of 'mojo'.

Changed

- Changed "About" section in client to indicate correct release version.

Added

- Added RPC updates to support keyring migration and to support adding a passphrase for wallets in an upcoming release.
- Added plot memo caching in PlotManager, speeding initial loading and cached loading, by enabling harvester to save the parsed plot memo on disk on shutdown, then load it back into memory on startup so that it can skip key parsing calculations for all already known plots.
- Added a debug option to log all SQL commands.
- Added support for DID, our decentralized identity solution, as a building block toward Chia's broader set of DID capabilities.
- Thanks olivernyc for the addition of a query in CoinStore to special case height 0 to avoid querying all unspent coins.
- Starting logging the timing of applying additions and removals to the coin store.
- Made max message size configurable in config.yaml, as a possible workaround for very large farms where reporting plot information exceeds the maximum message size.
- Added a config option for peer_connect_timeout.
- Added support for unhardened key derivations.
- Various CoinStore benchmark and performance improvements.
- Beta builds are built on every merge to main, and are now available from <https://chia.net/download/>.
- Thanks Radexito for adding support for Raspberry Pi 4 64Bit to the GUI installation script.
- Added macOS keyring.yaml support, migrating keys from macOS Keychain to keyring.yaml to support an upcoming release in which we'll add an optional passphrase to wallets.
- We have made many full node changes to support our upcoming Chia Asset Token (CAT) standard and our upcoming standalone light wallet, which will use Chia's new electrum-style protocol to enable faster wallet syncing.

- Made a change to remove CoinStore's dependency on FullBlock to just pass in the parts of the block necessary to add the block.
- Improved log formatting.
- A change to logging to only log warnings when more than 10 seconds has passed, to reduce the number of warning logs.
- Improved and fixed some outdated messages in CLI. Thanks jack60612 for the assist!
- We previously added a Rust condition checker, to replace our existing Python-based condition checker. In this release, we're removing the old Python code.
- Several clvm_rs updates to support our upcoming Chia Asset Token (CAT) standard.

Fixed

- Thanks mgraczyk for the fix to keyring_path.
- Fixed an issue blocking the Ubuntu installer that required manual installation of Python 3.9 as a workaround.
- Fixed an issue where the config.yaml and keyring.yaml are only partially written out to, if another process is attempting to read the config while it's being written.
- Fixed rmtree call in create_pool_plot.
- Thanks Knight1 for fixing an issue in which fix-ssl-permissions shows the current 'mode' not the 'updated mode'.
- Fixed Mypy issues on Python 3.9.7 that generated many errors when running mypy.
- Thanks olivernyc for fixing an edge case with negative inputs to 'truncate_to_significant_bits'.
- Added a fix for Windows installs that were seeing exceptions when writing to the keyring.

Fixed

- Thanks to jack60612 for fixing a bug that displayed 25 words instead of 24 words in some instances in the GUI.

Today we’re releasing version 1.2.6 to address a resource bug with nodes, and we want to stress the importance of updating to it at the earliest convenience. The fix prevents a node from consuming excessive memory when many Bluebox Timelords are active on the chain.

Changed

- Updated to BLS 1.0.6.
- Updates to the Rust conditions parser.
- Adjusted plot refresh parameter to improve plot loading times.

Fixed

- Fixed memory utilization issue related to how the node handles compact VDFs generated from blueboxes. We recommend everyone update to this version to avoid memory issues that can impact farming and harvesting.
- Fixed issues with reloading plot files detected as bad (this can happen during plot copying).
