Bcoin Release Notes & Changelog

v1.0.0-beta.14

Notable Changes

• pkg - Ignored bcoin* files in npmignore have been removed. This fixes the npm install.

v1.0.0-beta.13

Notable Changes

• config - Options using megabyte units are now calculated properly again (6182df0442, a630d23a97, 7728a00470).

• address - Bech32 addresses are now supported (6acef06cbc). This changes the semantics of the Address object: to support bech32, Address.fromBase58 calls should be replaced with Address.fromString. Likewise, addr.toBase58 calls should be replaced with addr.toString

• rpc - getblockbyheight is now exposed via JSON-RPC. It takes the same parameters as the getblock call, requiring a height instead of block hash (12d3ee6f95).

• bin - bcoin --version and bcoin --help now exit with appropriate messages (f2f94a800e).

• net - The p2p pool now exposes an --only option (a1d0948f2e).

• mempool - The mempool indexAddress option should now work correctly (fba9b46d25).

• rpc - JSON-RPC calls now properly cast booleans a la bitcoin core (dd49ee0761).

• rpc - Various RPC calls have been improved and updated (c78707ed6a, c1e684dc12, 5bde338a53).

• rpc - Retroactive pruning is now available via the pruneblockchain call (f0bc6d5925).

• http - Getting block by height via the Rest API now works again (df4c8cc68c).

• net - Peers who serve invalid orphans are now punished properly (0ceca23cb5).

• utils - An implementation of GCS filters is now supported (b994c278f2).

• http - The witness option is now properly exposed on the Rest API for segwit wallets (f04ad612b2).

• deps - Node.js >=v7.6.0 is now a required dependency (a0bd9680fe).

• build - The browser build has switched from browserify to webpack (19f236f740).

• bcoin - The codebase has been rewritten to use all ES6 and ES7 features supported by node.js (aa05bb5df7, 78d62c73b8, e00472891d, c53f4cf89e, 8c7279518f).

• workers - The worker pool has been refactored to solve the dissonance between the browser and node.js (27c60ce76e).

• net - DNS requests should now timeout sooner (647b6909c6).

• http - Satoshi values are now required for all JSON serialization, as opposed to BTC strings which were used in the past (2f51fd1c50).

• bin - The --no-wallet flag is now exposed for nodes who want to run without a wallet.

• chain - BIP91 support is now exposed via the --bip91 option. The segwit and segsignal rules will be automatically added when calling getblocktemplate. To enable bip91 on an existing database --force-flags must be passed. This will force bip91 to be enforced, but will not invalidate any previous blocks (bcoin cli reset [height] may need to be used).

• chain - BIP148 support is now exposed via the --bip148 option. This likewise must be enabled with --force-flags on existing chains. This has the same potential "reset" implications as the --bip91 option.

Migrating

This release contains a few non-backward-compatible changes.

Bcoin now requires node.js >=7.6.0 due to the use of ES6/7 features, and for the sake of more stability.

Bcoin's rest API now assumes satoshi values for in all JSON serialization. This is a breaking change for code that is not aware of it. All code which hits the rest API must be updated to use only satoshi values as opposed to BTC strings.

In other words, this:

{
  "unconfirmed": "1.12",
  "confirmed": "1.12"
}

Becomes this:

{
  "unconfirmed": 112000000,
  "confirmed": 112000000
}

v1.0.0-beta.12

Notable Changes

• networks - Fixed simnet wpkh prefix.
• http - wallet join without wallet auth has been fixed for responses. This was causing a hanging issue with the client.

v1.0.0-beta.11

Notable Changes

• networks - Simnet params have been fixed.
• cli - Chain reset call has been fixed.

v1.0.0-beta.10

Notable Changes

• wallet/http - Create wallet route modified (POST /wallet/:id? changed to PUT /wallet/:id).
• wallet/http - Create account route modified (POST /wallet/:id/account/:account? changed to PUT /wallet/:id/account/:account).
• wallet/http - auth socket.io event name for wallet auth changed to wallet auth.
• config - payout-address option was changed to coinbase-address.
• node - Plugin system is now exposed. See https://github.com/bcoin-org/bcoin/pull/156.
• config - The internal API for the config object has been rewritten and is now more reusable, particularly by node plugins.
• http/rpc - Both the HTTPBase and RPCBase objects now allow "mounting" by other rpc and http servers.
• wallet - The wallet code has been completely removed from the node, and now resides entirely within one module. The wallet is exposed only as a plugin or a separate server.
• rpc - prioritisetransaction is now exposed properly (deltaFees are now tracked on mempool entries).
• rpc - Proper id and error codes are now implemented.
• rpc - Several getblocktemplate improvements have been implemented for more accuracy. e.g. curtime will now be updated each call.
• mining - The internal miner API has been rewritten, and now mimics stratum in a sense.
• chain - Faster verification with checkpoints.
• net - Fixed a potential block stalling issue.
• net - Hardcoded seeds for main added. Makes for better shipping with browsers.
• wsproxy/proxysocket - DNS resolution is no longer exposed.
• logger - Log files now trim to 20mb on boot.
• hostlist - A persistent hosts file is now written by default.

v1.0.0-beta.9

Notable Changes

• mempool - Trimming now removes dependency chains by cumulative fee rate.
• mempool - Cumulative descendant fees are now updated properly when removing a transaction.
• net - Preliminary upnp support for adding port mappings.
• chain/mempool/miner - Various atomicity fixes and extra sanity checking.

v1.0.0-beta.8

Notable Changes

• mempool - Fixed critical fee estimator bug causing throwing in the mempool.

v1.0.0-beta.7

Notable Changes

• http - Always display spent coins in tx routes (e.g. /tx/[txid]).
• mempool - An on-disk mempool is now exposed via --persistent-mempool (also makes fee data persistent).
• chain - chain.add now takes a flags parameter to avoid POW and non-contextual checks if necessary.
• net - HostList is now potentially persistent with a hostLocation option.
• net - Smarter stall behavior and timeouts.

• miner - Improved fee rate sorting.
• rpc - Fix incompatibilities in rpc api (getblocktemplate & submitblock).

v1.0.0-beta.2

Notable Changes

• pool - Increase max header chain failures to 500 (prevents the initial sync from reverting to getblocks so frequently).

v1.0.0-beta.1

Notable Changes

• wsproxy: Fixed proof of work handling in websocket proxy (43c491b).
• chain: Optimized MTP and network target calculations (1e07d1b).
