# 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
|
|
(6182df044228f9215938e7d314435f3f2640acca,
|
|
a630d23a97b68f189a85105856fedc4e9e515754,
|
|
7728a0047053d4c368e60426e5fc7cc812d54caf).
|
|
|
|
- __address__ - Bech32 addresses are now supported
|
|
(6acef06cbc87a3051ba238a2fb640562e718135e). 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
|
|
(12d3ee6f9582afa9a3ba8984c63dcbc27b8db57e).
|
|
|
|
- __bin__ - `bcoin --version` and `bcoin --help` now exit with appropriate
|
|
messages (f2f94a800e37c5dbdda6920fa6b85fbd485c212a).
|
|
|
|
- __net__ - The p2p pool now exposes an `--only` option
|
|
(a1d0948f2e528c5d77d6502659fafd064b1e693b).
|
|
|
|
- __mempool__ - The mempool `indexAddress` option should now work correctly
|
|
(fba9b46d253c19bbf8e662d9d75ab03dc9e20a78).
|
|
|
|
- __rpc__ - JSON-RPC calls now properly cast booleans a la bitcoin core
|
|
(dd49ee076196d2353783e3044185165dbac4aeb9).
|
|
|
|
- __rpc__ - Various RPC calls have been improved and updated
|
|
(c78707ed6a71ce46c41c4e43ecb505e78a84b380,
|
|
c1e684dc12d0a86573a905d54d4f81fce921987a,
|
|
5bde338a53117b1bd0fd92df0abc23d95180ab32).
|
|
|
|
- __rpc__ - Retroactive pruning is now available via the `pruneblockchain` call
|
|
(f0bc6d5925419ba4a8289fa7828efc48ecc152d4).
|
|
|
|
- __http__ - Getting block by height via the Rest API now works again
|
|
(df4c8cc68c965bd818a5004354d2652751d4a702).
|
|
|
|
- __net__ - Peers who serve invalid orphans are now punished properly
|
|
(0ceca23cb5a3d724c79c6bf587ede5d473df8486).
|
|
|
|
- __utils__ - An implementation of GCS filters is now supported
|
|
(b994c278f25408886c3095d0c24123baaf07f78f).
|
|
|
|
- __http__ - The `witness` option is now properly exposed on the Rest API for
|
|
segwit wallets (f04ad612b216becd35765c6e231f7820c7eee358).
|
|
|
|
- __deps__ - Node.js >=v7.6.0 is now a required dependency
|
|
(a0bd9680fed07c5eb37c227d160b0868f8adaf31).
|
|
|
|
- __build__ - The browser build has switched from browserify to webpack
|
|
(19f236f74072d473123d20282d2119f6d9130458).
|
|
|
|
- __bcoin__ - The codebase has been rewritten to use all ES6 and ES7 features
|
|
supported by node.js
|
|
(aa05bb5df79d9a3af53060a4c0c066226f6e9e4c,
|
|
78d62c73b82e1953999d1cf80c90ed2035d4996e,
|
|
e00472891df5934d8fc3aa63662f852816aa86b0,
|
|
c53f4cf89e46d9de8ab7f65430310567558fe03f,
|
|
8c7279518f5341a2482a79ac98f0574468541edc).
|
|
|
|
- __workers__ - The worker pool has been refactored to solve the dissonance
|
|
between the browser and node.js (27c60ce76e57af1695d78f912227d93194812c88).
|
|
|
|
- __net__ - DNS requests should now timeout sooner
|
|
(647b6909c6d527eb82f6d789c88a23b2f8a60126).
|
|
|
|
- __http__ - Satoshi values are now required for all JSON serialization, as
|
|
opposed to BTC strings which were used in the past
|
|
(2f51fd1c5066f194a5a52383f4dd45497b882706).
|
|
|
|
- __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:
|
|
|
|
``` json
|
|
{
|
|
"unconfirmed": "1.12",
|
|
"confirmed": "1.12"
|
|
}
|
|
```
|
|
|
|
Becomes this:
|
|
|
|
``` json
|
|
{
|
|
"unconfirmed": 112000000,
|
|
"confirmed": 112000000
|
|
}
|
|
```
|
|
|
|
