============================================================================
User visible changes for btcd
A full-node bitcoin implementation written in Go
============================================================================
Changes in 0.4.0 (Thu Dec 12 2013)
- Allow listen interfaces to be specified via --listen instead of only the
port (https://github.com/conformal/btcd/issues/33)
- Allow listen interfaces for the RPC server to be specified via
--rpclisten instead of only the port
(https://github.com/conformal/btcd/issues/34)
- Only disable listening when --connect or --proxy are used when no
--listen interface are specified
(https://github.com/conformal/btcd/issues/10)
- Add several new standard transaction checks to transaction memory pool:
- Support nulldata scripts as standard
- Only allow a max of one nulldata output per transaction
- Enforce a maximum of 3 public keys in multi-signature transactions
- The number of signatures in multi-signature transactions must not
exceed the number of public keys
- The number of inputs to a signature script must match the expected
number of inputs for the script type
- The number of inputs pushed onto the stack by a redeeming signature
script must match the number of inputs consumed by the referenced
public key script
- When a block is connected, remove any transactions from the memory pool
which are now double spends as a result of the newly connected
transactions
- Don't relay transactions resurrected during a chain switch since
other peers will also be switching chains and therefore already know
about them
- Cleanup a few cases where rejected transactions showed as an error
rather than as a rejected transaction
- Ignore the default configuration file when --regtest (regression test
mode) is specified
- Implement TLS support for RPC including automatic certificate generation
- Support HTTP authentication headers for web sockets
- Update address manager to recognize and properly work with Tor
addresses (https://github.com/conformal/btcd/issues/36) and
(https://github.com/conformal/btcd/issues/37)
- Improve btcctl utility in the following ways:
- Add the ability to specify a configuration file
- Add a default entry for the RPC cert to point to the location
it will likely be in the btcd home directory
- Implement --version flag
- Provide a --notls option to support non-TLS configurations
- Fix a couple of minor races found by the Go race detector
- Improve logging
- Allow logging level to be specified on a per subsystem basis
(https://github.com/conformal/btcd/issues/48)
- Allow logging levels to be dynamically changed via RPC
(https://github.com/conformal/btcd/issues/15)
- Implement a rolling log file with a max of 10MB per file and a
rotation size of 3 which results in a max logging size of 30 MB
- Correct a minor issue with the rescanning websocket call
(https://github.com/conformal/btcd/issues/54)
- Fix a race with pushing address messages that could lead to a panic
(https://github.com/conformal/btcd/issues/58)
- Improve which external IP address is reported to peers based on which
interface they are connected through
(https://github.com/conformal/btcd/issues/35)
- Add --externalip option to allow an external IP address to be specified
for cases such as tor hidden services or advanced network configurations
(https://github.com/conformal/btcd/issues/38)
- Add --upnp option to support automatic port mapping via UPnP
(https://github.com/conformal/btcd/issues/51)
- Update Ctrl+C interrupt handler to properly sync address manager and
remove the UPnP port mapping (if needed)
- Continue cleanup and work on implementing RPC API calls
- Add importprivkey (import private key) command to btcctl
- Update getrawtransaction to provide addresses properly, support
new verbose param, and match the reference implementation with the
exception of MULTISIG (thanks @flammit)
- Update getblock with new verbose flag (thanks @flammit)
- Add listtransactions command to btcctl
- Add getbalance command to btcctl
- Add basic support for btcd to run as a native Windows service
(https://github.com/conformal/btcd/issues/42)
- Package addblock utility with Windows MSIs
- Add support for TravisCI (continuous build integration)
- Cleanup some documentation and usage
- Several other minor bug fixes and general code cleanup
Changes in 0.3.3 (Wed Nov 13 2013)
- Significantly improve initial block chain download speed
(https://github.com/conformal/btcd/issues/20)
- Add a new checkpoint at block height 267300
- Optimize most recently used inventory handling
(https://github.com/conformal/btcd/issues/21)
- Optimize duplicate transaction input check
(https://github.com/conformal/btcchain/issues/2)
- Optimize transaction hashing
(https://github.com/conformal/btcd/issues/25)
- Rework and optimize wallet listener notifications
(https://github.com/conformal/btcd/issues/22)
- Optimize serialization and deserialization
(https://github.com/conformal/btcd/issues/27)
- Add support for minimum transaction fee to memory pool acceptance
(https://github.com/conformal/btcd/issues/29)
- Improve leveldb database performance by removing explicit GC call
- Fix an issue where Ctrl+C was not always finishing orderly database
shutdown
- Fix an issue in the script handling for OP_CHECKSIG
- Impose max limits on all variable length protocol entries to prevent
abuse from malicious peers
- Enforce DER signatures for transactions allowed into the memory pool
- Separate the debug profile http server from the RPC server
- Rework of the RPC code to improve performance and make the code cleaner
- The getrawtransaction RPC call now properly checks the memory pool
before consulting the db (https://github.com/conformal/btcd/issues/26)
- Add support for the following RPC calls: getpeerinfo, getconnectedcount,
addnode, verifychain
(https://github.com/conformal/btcd/issues/13)
(https://github.com/conformal/btcd/issues/17)
- Implement rescan websocket extension to allow wallet rescans
- Use correct paths for application data storage for all supported
operating systems (https://github.com/conformal/btcd/issues/30)
- Add a default redirect to the http profiling page when accessing the
http profile server
- Add a new --cpuprofile option which can be used to generate CPU
profiling data on platforms that support it
- Several other minor performance optimizations
- Other minor bug fixes and general code cleanup
Changes in 0.3.2 (Tue Oct 22 2013)
- Fix an issue that could cause the download of the block chain to stall
(https://github.com/conformal/btcd/issues/12)
- Remove deprecated sqlite as an available database backend
- Close sqlite compile issue as sqlite has now been removed
(https://github.com/conformal/btcd/issues/11)
- Change default RPC ports to 8334 (mainnet) and 18334 (testnet)
- Continue cleanup and work on implementing RPC API calls
- Add support for the following RPC calls: getrawmempool,
getbestblockhash, decoderawtransaction, getdifficulty,
getconnectioncount, getpeerinfo, and addnode
- Improve the btcctl utility that is used to issue JSON-RPC commands
- Fix an issue preventing btcd from cleanly shutting down with the RPC

- Other minor bug fixes and general code cleanup
Changes in 0.3.1-alpha (Tue Oct 15 2013)
- Change default database to leveldb
NOTE: This does mean you will have to redownload the block chain. Since we
are still in alpha, we didn't feel writing a converter was worth the time as
it would take away from more important issues at this stage
- Add a warning if there are multiple block chain databases of different types
- Fix issue with unexpected EOF in leveldb -- https://github.com/conformal/btcd/issues/18

- Optimize transaction lookups
- Correct a few cases of list removal that could result in improper cleanup
of no longer needed orphans
- Add functionality to increase ulimits on non-Windows platforms
- Add support for mempool command which allows remote peers to query the
transaction memory pool via the bitcoin protocol
- Clean up logging a bit
- Add a flag to disable checkpoints for developers
- Add a lot of useful debug logging such as message summaries
- Other minor bug fixes and general code cleanup

- Initial release
