Release 0.20

Changes

• Don't enforce daemon owning pool wallet if payment-processing is disabled
• Persistence configuration is optional if payment-processing is disabled and the pool is in relay-mode
• Share relay config
• Dummy persistence
• Bitcoin ZMQ block notify topic is now configurable
• Share relay connect option
• BTCP explorer links
• ZCash & BTCP PowLimit configuration

Database Migration

ALTER TABLE shares ADD source TEXT NULL;

Release 19

Changes

• BalanceChange API
• Fix ZCash shielding for coins other than ZCash (ZCL, ZEN, BTCP etc)
• Fixed t-addr balance calculation for ShieldCoinbaseEmulatedAsync (ZCL, ZEN, BTCP etc)
• Support multiple external stratums

Breaking Changes

• Pool configuration option externalStratum has been removed
• Pool configuration options externalStratumZmqSocket and externalStratumZmqTopic have been replaced by an array of objects:

"externalStratums": [{
    "url": "tcp://localhost:13032",
    "topic": "xmr1"
}]

Release 18

• Payment Processing crash fix (invalid tablename balances_changes)
• Drop Id column for shares table
• Add index on table balance_changes
• API Hashrate case consolidation

Database Migration

Miningcore needs to be stopped briefly for the following change:

ALTER TABLE shares DROP id;

Other migrations:

CREATE INDEX IDX_BALANCE_CHANGES_POOL_ADDRESS_CREATED on balance_changes(poolid, address, created desc);

Database Migration

DROP INDEX IDX_SHARES_POOL_BLOCK;
CREATE INDEX IDX_SHARES_POOL_MINER_DIFFICULTY on shares(poolid, miner, difficulty);
ALTER TABLE blocks ADD miner TEXT NULL;

CREATE TABLE balance_changes
(
	id BIGSERIAL NOT NULL PRIMARY KEY,
	poolid TEXT NOT NULL,
	coin TEXT NOT NULL,
	address TEXT NOT NULL,
	amount decimal(28,12) NOT NULL DEFAULT 0,
	usage TEXT NULL,
	created TIMESTAMP NOT NULL
);

Release 0.16

Changes

• Made RPC polling optional
• Update configuration examples to be closer to real world usage
• Added no RPC polling config example
• Don't expose payment processing config extension data via API. Fixes #103
• Keep extra data in api result but sanitize it first
• Increase PG command timeout
• Add support for ZEN and XVG
• Return Coin POW Algorithm in API results
• Expose pool total miner earnings via API
• Improved LTC block explorer links
• Neoscrypt update
• Neoscrypt tests
• Support GBX, CRC and XVG (Verge)
• Don't tie ZMQ block notify to a single address. Fixes #183
• X17 hash integration
• Drop paged retries from Monero Payments as those won't work anyway when transfer_split fails.
• Support Verge X17 variant
• Added support for MaxActiveJobs Bitcoin Pool extra config

Configuration Changes

• The pool configuration parameter zmqBlockNotifySocket introduced in the previous release, has been moved to the daemon configuration element to enable receiving block update notifications from multiple daemons as a single unified notification stream.

Release 0.15

Changes

• Support ZMQ block notify for Bitcoin family. Fixes #151.
• Adjust Lyra2v2 Hashrate multiplier. Fixes #168
• Made RPC polling optional
• Updated configuration examples to be closer to real world usage
• Added no-RPC-polling config example

Notes

We now support streaming Block Notifications via ZeroMQ messaging from Bitcoin Family daemons. This greatly reduces the latency for detecting new blocks, while eliminating the need for aggressively fast polling for updates. This is achieved by the new configuration option zmqBlockNotifySocket at the pool-configuration root level. The value of this option is a string that should match the value of the -zmqpubhashblock parameter passed to the coin daemon.

Release 0.14
