Changes in 0.12.0 (Fri Nov 20 2015)
|
|
- Protocol and network related changes:
|
|
- Add a new checkpoint at block height 382320 (#555)
|
|
- Implement BIP0065 which includes support for version 4 blocks, a new
|
|
consensus opcode (OP_CHECKLOCKTIMEVERIFY) that enforces transaction
|
|
lock times, and a double-threshold switchover mechanism (#535, #459,
|
|
#455)
|
|
- Implement BIP0111 which provides a new bloom filter service flag and
|
|
hence provides support for protocol version 70011 (#499)
|
|
- Add a new parameter --nopeerbloomfilters to allow disabling bloom
|
|
filter support (#499)
|
|
- Reject non-canonically encoded variable length integers (#507)

|
|
fee in BTC/kB to be overridden (#520)

- Retain memory pool transactions when they redeem another one that is
|
|
removed when a block is accepted (#539)

|
|
times when the transaction they redeem is added (#551)

|
|
instead of full kilobyte boundaries (#521, #537)

|
|
results to only include inputs and outputs which involve the
|
|
provided addresses (#516)

|
|
transactions (recvtx, redeemingtx) before the blockconnected

Changes in 0.10.0 (Sun Mar 01 2015)
|
|
- Protocol and network related changes:
|
|
- Add a new checkpoint at block height 343185
|
|
- Implement BIP066 which includes support for version 3 blocks, a new
|
|
consensus rule which prevents non-DER encoded signatures, and a
|
|
double-threshold switchover mechanism
|
|
- Rather than announcing all known addresses on getaddr requests which
|
|
can possibly result in multiple messages, randomize the results and
|
|
limit them to the max allowed by a single message (1000 addresses)
|
|
- Add more reserved IP spaces to the address manager
|
|
- Transaction relay (memory pool) changes:
|
|
- Make transactions which contain reserved opcodes nonstandard
|
|
- No longer accept or relay free and low-fee transactions that have
|
|
insufficient priority to be mined in the next block
|
|
- Implement support for the following rules specified by BIP0062:
|
|
- ECDSA signature must use strict DER encoding (rule 1)
|
|
- The signature script must only contain push operations (rule 2)
|
|
- All push operations must use the smallest possible encoding (rule 3)
|
|
- All stack values interpreted as a number must be encoding using the
|
|
shortest possible form (rule 4)
|
|
- NOTE: Rule 1 was already enforced, however the entire script now
|
|
evaluates to false rather than only the signature verification as
|
|
required by BIP0062
|
|
- Allow transactions with nulldata transaction outputs to be treated as
|
|
standard
|
|
- Mining support changes:
|
|
- Modify the getblocktemplate RPC to generate and return block templates
|
|
for version 3 blocks which are compatible with BIP0066
|
|
- Allow getblocktemplate to serve blocks when the current time is
|
|
less than the minimum allowed time for a generated block template
|
|
(https://github.com/btcsuite/btcd/issues/209)
|
|
- Crypto changes:
|
|
- Optimize scalar multiplication by the base point by using a
|
|
pre-computed table which results in approximately a 35% speedup
|
|
(https://github.com/btcsuite/btcec/issues/2)
|
|
- Optimize general scalar multiplication by using the secp256k1
|
|
endomorphism which results in approximately a 17-20% speedup
|
|
(https://github.com/btcsuite/btcec/issues/1)
|
|
- Optimize general scalar multiplication by using non-adjacent form
|
|
which results in approximately an additional 8% speedup
|
|
(https://github.com/btcsuite/btcec/issues/3)
|
|
- Implement optional address indexing:
|
|
- Add a new parameter --addrindex which will enable the creation of an
|
|
address index which can be queried to determine all transactions which
|
|
involve a given address
|
|
(https://github.com/btcsuite/btcd/issues/190)
|
|
- Add a new logging subsystem for address index related operations
|

|
|
- Provide support for disabling TLS when only listening on localhost

|
(https://github.com/btcsuite/btcd/pull/192)
|
|
- Modify help output for all commands to provide much more consistent
|
|
and detailed information
|
|

|
|
transactions with invalid scripts
|
|
(https://github.com/btcsuite/btcd/issues/210)
|
|
- Correct error handling in the getrawtransaction RPC which could lead
|
|
to a crash in rare cases
|
|
(https://github.com/btcsuite/btcd/issues/196)
|
|
- Update getinfo RPC to include the appropriate 'timeoffset' calculated
|
|
from the median network time

|
|
is compatible

|
|
zero
|
|
- Websocket changes:
|
|
- Modify the behavior of the rescan command to automatically register
|
|
for notifications about transactions paying to rescanned addresses
|
|
or spending outputs from the final rescan utxo set when the rescan
|
|
is through the best block in the chain
|
|
- btcctl utility changes:
|
|
- Make the list of commands available via the -l option rather than
|
|
dumping the entire list on usage errors
|
|
- Alphabetize and categorize the list of commands by chain and wallet
|
|
- Make the help option only show the help options instead of also
|
|
dumping all of the commands
|
|

|
|
misnamed fields
|
|
(https://github.com/btcsuite/btcd/issues/305)
|

|
|
and error code
|
|
- Only show the usage for specific command is shown when a valid command
|
|
is provided with invalid parameters

|
|
redesigned from the ground up based based upon how the project has
|
|
evolved and lessons learned while using it since it was first written
|
|
is now available in the btcjson/v2/btcjson directory
|
|
- This will ultimately replace the current version so anyone making
|
|
use of this package will need to update their code accordingly
|
|
- The btcec package now provides better facilities for working directly
|
|
with its public and private keys without having to mix elements from
|
|
the ecdsa package
|
|

|
|
adhered to when creating scripts
|
|

concrete implementation for providing time samples from remote peers
|
|
and using that data to calculate an offset against the local time

|
- Fix a slow memory leak due to tickers not being stopped
|
|
(https://github.com/btcsuite/btcd/issues/189)

|
|
condition where peers would no longer be served
|
|

- The RPC username and password can now contain symbols which previously
|
|
conflicted with special symbols used in URLs
|

|
|
of unmounted symlinks (https://github.com/btcsuite/btcd/issues/193)
|

- Improve the error reporting for rejected transactions to include the
|
|
inputs which are missing and/or being double spent

|
|
(https://github.com/btcsuite/btcd/issues/218)
|

- Update the continuous integration builds to run several tools which
|
|
help keep code quality high
