v10.1.2

Release Notes - Counterparty Core v10.1.2 (2024-05-08)

This version of Counterparty Core marks the release of API v2, a new RESTful API—see the official project documentation. The new API is available at /v2/, while the old API is now available at /v1/ in addition to /.

Upgrading

There is a guide for migrating from the v1 to the v2 API in the documentation, which specifies equivalences between old and new functionality.

This release maintains full backwards-compatibility and includes no protocol changes.

v10.1.1

Release Notes - Counterparty Core v10.1.1 (2024-04-19)

This is a relatively small release with a number of bugfixes, one of which is critical---in v10.0.x and v10.1.0 there is a bug which can cause nodes to crash upon a blockchain reorganization.

Upgrading

To upgrade from v10.1.0 manually, you must first uninstall the following Counterparty Core Python packages:

pip3 uninstall counterparty-rs counterparty-lib counterparty-cli

This release contains no protocol changes, and the API has not been modified.

ChangeLog

Bugfixes

• Fix missing events (NEW_BLOCK and NEW_TRANSACTION) when kickstarting and reparsing. To correct the values in the messages table, a full reparse is required.
• Fix the current block index after a blockchain reorganisation.
• Fix database shutdown, which caused a recovery of the WAL file on each startup.
• Eliminate some extraneous error messages

Codebase

• Merge counterparty-lib and counterparty-core package into counterparty-core
• Integrate telemetry with optional Sentry service

Command-Line Interface

• Replace --no-check-asset-conservation with --check-asset-conservation
• Disable automatic DB integrity check on startup

v10.1.0

Release Notes - Counterparty Core v10.1.0 (2024-04-16)

This release includes fixes for a number of bugs as well as a few regressions in v10.0.x.

Upgrade Procedure

This upgrade is optional but highly recommended. Upgrading from v10.0.x requires an automatic reparse from block 835,500 on mainnet, which should take a few minutes. If you are upgrading directly from v9.x.y, then there will be an automatic full database rebuild, which may take a long time (refer to the release notes for v10.0.0.)

In order to perform a manual installation, you must first uninstall all existing Counterparty Core Python packages:

pip3 uninstall counterparty-rs counterparty-lib counterparty-cli

ChangeLog

Bugfixes

• Validate non-empty block_indexes in call to api.get_blocks (fix for #1621)
• Reproduce order expiration bug in v9.61.x (fix for #1631)
• Fix get_blocks call when several block indexes are provided (fix for #1629)
• Fix create_send when one of the outputs is a dispenser (fix for #1119)
• Fix get_dispenser_info RPC call

Codebase

• Split out counterparty-cli package into counterparty-core and counterparty-wallet packages
• Implement heavy healthz probe (default to light)
• Automatic code checking and correction with Ruff
• Refactor transaction file singleton to class
• Run PRAGMA optimize on shutting down
• Run PRAGMA quick_check on database initialization
• Temporary disable asset conservation checking after each new block
• Add instrumentation for optional Sentry error and performance monitoring

Command-Line Interface

• Rename counterpary-client to counterparty-wallet
• Add --skip-db-check flag to skip database quick check
• Add --no-mempool flash to disable mempool parsing

v10.0.0

Release Notes - Counterparty Core v10.0.0 (2024-04-09)

Counterparty Core v10.0.0 is a very large release comprising many improvements across different portions of the codebase. “Counterparty Core” is also the new name for the codebase and repository that is the result of a merge between counterparty-lib, counterparty-cli and a new Rust library, counterparty-rs.

Upgrade Procedure

This release does not include any protocol changes, so there is no deadline for upgrading. However it is strongly recommended that all users upgrade as soon as possible, in particular to avoid consensus problems due to non-determinism in previous versions. The Counterparty Core API is also unchanged for this release. The minimum required version of AddrIndexRs has been increased to v0.4.6.

Because this release includes numerous changes to the database schema, a full database rebuild is required and the major version number has been bumped from 9 to 10. You may upgrade either by using Docker Compose or by installing Counterparty Core manually, following the installation instructions available in the official project documentation. When using kickstart, the database rebuild will happen automatically and take between 8 and 24 hours to complete.

ChangeLog

Codebase

• Upgrade from Python 3.7 to Python >= 3.10
• Support Ubuntu 22.04 and macOS officially
• Upgrade packaging system: replace setup.py with pyproject.toml and use Hatchling as a build system

• Rename counterparty-lib repository to counterparty-core. NOTE: The normal redirect for GitHub URLs cannot be implemented.
• Merge the counterparty-cli repository into the counterparty-core repository
• Add Rust library, counterparty-rs, for performance-critical code
• Synchronize versions of counterparty-rs, counterparty-lib and counterparty-cli

• Fix source of non-determinism in AddrIndexRs caused by txid_limit and get_oldest_tx
• Fix consensus break due to missing support for segwit transactions in kickstart logic
