+User visible changes for btcd
+  A full-node bitcoin implementation written in Go
+============================================================================
+
+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)
+    - Add mainnet peer discovery DNS seed (seed.bitcoin.jonasschnelli.ch)
+      (#496)
+    - Correct reconnect handling for persistent peers (#463, #464)
+    - Ignore requests for block headers if not fully synced (#444)
+    - Add CLI support for specifying the zone id on IPv6 addresses (#538)
+    - Fix a couple of issues where the initial block sync could stall (#518,
+      #229, #486)
+    - Fix an issue which prevented the --onion option from working as
+      intended (#446)
+  - Transaction relay (memory pool) changes:
+    - Require transactions to only include signatures encoded with the
+    canonical 'low-s' encoding (#512)
+    - Add a new parameter --minrelaytxfee to allow the minimum transaction
+      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)
+    - Do not send reject messages for a transaction if it is valid but
+      causes an orphan transaction which depends on it to be determined
+      as invalid (#546)
+    - Refrain from attempting to add orphans to the memory pool multiple
+      times when the transaction they redeem is added (#551)
+    - Modify minimum transaction fee calculations to scale based on bytes
+      instead of full kilobyte boundaries (#521, #537)

+    - Provides a limited memory cache of validated signatures which is a
+      huge optimization when verifying blocks for transactions that are
+      already in the memory pool (#506)

+        to include information about the outputs referenced by a transaction's
+        inputs (#485, #487)
+      - Skip entries in the mempool too (#495)
+      - Accept a new optional parameter 'reverse' to return the results in
+        reverse order (most recent to oldest) (#497)

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

+      transactions (recvtx, redeemingtx) before the blockconnected
+      notification (#449)

+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
+    - Support new searchrawtransactions RPC
+      (https://github.com/btcsuite/btcd/issues/185)
+  - RPC changes:
+    - Require TLS version 1.2 as the minimum version for all TLS connections
+    - 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
+    - Correct case in getrawtransaction which would refuse to serve certain
+      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
+    - Modify listreceivedbyaddress result type to include txids field so it
+      is compatible
+    - Add 'iswatchonly' field to validateaddress result
+    - Add 'startingpriority' and 'currentpriority' fields to getrawmempool
+      (https://github.com/btcsuite/btcd/issues/178)
+    - Don't omit the 'confirmations' field from getrawtransaction when it is
+      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
+    - Make the usage syntax much more consistent and correct a few cases of
+      misnamed fields
+      (https://github.com/btcsuite/btcd/issues/305)
+    - Improve usage errors to show the specific parameter number, reason,
+      and error code
+    - Only show the usage for specific command is shown when a valid command
+      is provided with invalid parameters
+    - Add support for a SOCK5 proxy
+    - Modify output for integer fields (such as timestamps) to display
+      normally instead in scientific notation
+    - Add invalidateblock command
+    - Add reconsiderblock command
+    - Add createnewaccount command
+    - Add renameaccount command
+    - Add searchrawtransactions command
+    - Add importaddress command
+    - Add importpubkey command
+  - showblock utility changes:
+    - Remove utility in favor of the RPC getblock method
+  - Notable developer-related package changes:
+    - Many of the core packages have been relocated into the btcd repository
+      (https://github.com/btcsuite/btcd/issues/214)
+    - A new version of the btcjson package that has been completely
+      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
+    - Update the script builder to ensure all rules specified by BIP0062 are
+      adhered to when creating scripts
+    - The blockchain package now provides a MedianTimeSource interface and
+      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)
+    - Fix an issue where a mix of orphans and SPV clients could trigger a
+      condition where peers would no longer be served
+      (https://github.com/btcsuite/btcd/issues/231)
+    - The RPC username and password can now contain symbols which previously
+      conflicted with special symbols used in URLs
+    - Improve handling of obtaining random nonces to prevent cases where it
+      could error when not enough entropy was available
+    - Improve handling of home directory creation errors such as in the case
+      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
+    - Update sample config file with new options and correct a comment
+      regarding the fact the RPC server only listens on localhost by default
+      (https://github.com/btcsuite/btcd/issues/218)
+    - Update the continuous integration builds to run several tools which
+      help keep code quality high
+    - Significant amount of internal code cleanup and improvements

+  - Add support for plan9 - thanks @mischief
+    (https://github.com/conformal/btcd/pull/19)
+  - 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
+  - Fix issue preventing block 21066 on testnet -- https://github.com/conformal/btcchain/issues/1
+  - Fix issue preventing block 96464 on testnet -- https://github.com/conformal/btcscript/issues/1
+  - 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

-Kaspad is the reference full node Kaspa implementation written in Go (golang).
+btcd is an alternative full node bitcoin implementation written in Go (golang).
 
-This project is currently under active development and is in a pre-Alpha state. 
-Some things still don't work and APIs are far from finalized. The code is provided for reference only.
+This project is currently under active development and is in a Beta state.  It
+is extremely stable and has been in production use since October 2013.
+
+It properly downloads, validates, and serves the block chain using the exact
+rules (including consensus bugs) for block acceptance as Bitcoin Core.  We have
+taken great care to avoid btcd causing a fork to the block chain.  It includes a
+full block validation testing framework which contains all of the 'official'
+block acceptance tests (and some additional ones) that is run on every pull
+request to help ensure it properly follows consensus.  Also, it passes all of
+the JSON test data in the Bitcoin Core code.
+
+It also properly relays newly mined blocks, maintains a transaction pool, and
+relays individual transactions that have not yet made it into a block.  It
+ensures all individual transactions admitted to the pool follow the rules
+required by the block chain and also includes more strict checks which filter
+transactions based on miner requirements ("standard" transactions).
+
+One key difference between btcd and Bitcoin Core is that btcd does *NOT* include
+wallet functionality and this was a very intentional design decision.  See the
+blog entry [here](https://blog.conformal.com/btcd-not-your-moms-bitcoin-daemon)
+for more details.  This means you can't actually make or receive payments
+directly with btcd.  That functionality is provided by the
+[btcwallet](https://github.com/btcsuite/btcwallet) and
+[Paymetheus](https://github.com/btcsuite/Paymetheus) (Windows-only) projects
+which are both under active development.

+Package addrmgr implements concurrency safe Bitcoin address manager.
+
+Address Manager Overview
+
+In order maintain the peer-to-peer Bitcoin network, there needs to be a source
+of addresses to connect to as nodes come and go.  The Bitcoin protocol provides
+the getaddr and addr messages to allow peers to communicate known addresses with
+each other.  However, there needs to a mechanism to store those results and
+select peers from them.  It is also important to note that remote peers can't
+be trusted to send valid peers nor attempt to provide you with only peers they
+control with malicious intent.
+
+With that in mind, this package provides a concurrency safe address manager for
+caching and selecting peers in a non-deterministic manner.  The general idea is
+the caller adds addresses to the address manager and notifies it when addresses
+are connected, known good, and attempted.  The caller also requests addresses as
+it needs them.
+
+The address manager internally segregates the addresses into groups and
+non-deterministically selects groups in a cryptographically random manner.  This
+reduce the chances multiple addresses from the same nets are selected which
+generally helps provide greater peer diversity, and perhaps more importantly,
+drastically reduces the chances an attacker is able to coerce your peer into
+only connecting to nodes they control.
+
+The address manager also understands routability and Tor addresses and tries
+hard to only return routable addresses.  In addition, it uses the information
+provided by the caller about connected, known good, and attempted addresses to
+periodically purge peers which no longer appear to be good peers as well as
+bias the selection toward known good peers.  The general idea is to make a best
+effort at only providing usable addresses.

-Package wire implements the kaspa wire protocol.
-
-## Kaspa Message Overview
-
-The kaspa protocol consists of exchanging messages between peers. Each message
-is preceded by a header which identifies information about it such as which
-kaspa network it is a part of, its type, how big it is, and a checksum to
-verify validity. All encoding and decoding of message headers is handled by this
-package.
-
-To accomplish this, there is a generic interface for kaspa messages named
-`Message` which allows messages of any type to be read, written, or passed
-around through channels, functions, etc. In addition, concrete implementations
-of most all kaspa messages are provided. All of the details of marshalling and 
-unmarshalling to and from the wire using kaspa encoding are handled so the 
-caller doesn't have to concern themselves with the specifics.
-
-## Reading Messages Example
-
-In order to unmarshal kaspa messages from the wire, use the `ReadMessage`
-function. It accepts any `io.Reader`, but typically this will be a `net.Conn`
-to a remote node running a kaspa peer. Example syntax is:
-
-```Go
-	// Use the most recent protocol version supported by the package and the
-	// main kaspa network.
-	pver := wire.ProtocolVersion
-	kaspanet := wire.Mainnet
-
-	// Reads and validates the next kaspa message from conn using the
-	// protocol version pver and the kaspa network kaspanet. The returns
-	// are a appmessage.Message, a []byte which contains the unmarshalled
-	// raw payload, and a possible error.
-	msg, rawPayload, err := wire.ReadMessage(conn, pver, kaspanet)
-	if err != nil {
-		// Log and handle the error
-	}
-```
-
-See the package documentation for details on determining the message type.
-
-## Writing Messages Example
-
-In order to marshal kaspa messages to the wire, use the `WriteMessage`
-function. It accepts any `io.Writer`, but typically this will be a `net.Conn`
-to a remote node running a kaspa peer. Example syntax to request addresses
-from a remote peer is:
-
-```Go
-	// Use the most recent protocol version supported by the package and the
-	// main bitcoin network.
-	pver := wire.ProtocolVersion
-	kaspanet := wire.Mainnet
-
-	// Create a new getaddr kaspa message.
-	msg := wire.NewMsgGetAddr()
-
-	// Writes a kaspa message msg to conn using the protocol version
-	// pver, and the kaspa network kaspanet. The return is a possible
-	// error.
-	err := wire.WriteMessage(conn, msg, pver, kaspanet)
-	if err != nil {
-		// Log and handle the error
-	}
-```

-Package appmessage implements the kaspa appmessage protocol.
-
-At a high level, this package provides support for marshalling and unmarshalling
-supported kaspa messages to and from the appmessage. This package does not deal
-with the specifics of message handling such as what to do when a message is
-received. This provides the caller with a high level of flexibility.
-
-Kaspa Message Overview
-
-The kaspa protocol consists of exchanging messages between peers. Each
-message is preceded by a header which identifies information about it such as
-which kaspa network it is a part of, its type, how big it is, and a checksum
-to verify validity. All encoding and decoding of message headers is handled by
-this package.
-
-To accomplish this, there is a generic interface for kaspa messages named
-Message which allows messages of any type to be read, written, or passed around
-through channels, functions, etc. In addition, concrete implementations of most
-of the currently supported kaspa messages are provided. For these supported
-messages, all of the details of marshalling and unmarshalling to and from the
-appmessage using kaspa encoding are handled so the caller doesn't have to concern
-themselves with the specifics.
-
-Message Interaction
-
-The following provides a quick summary of how the kaspa messages are intended
-to interact with one another. As stated above, these interactions are not
-directly handled by this package.
-
-The initial handshake consists of two peers sending each other a version message
-(MsgVersion) followed by responding with a verack message (MsgVerAck). Both
-peers use the information in the version message (MsgVersion) to negotiate
-things such as protocol version and supported services with each other. Once
-the initial handshake is complete, the following chart indicates message
-interactions in no particular order.
-
-	Peer A Sends                            Peer B Responds
-	----------------------------------------------------------------------------
-	getaddr message (MsgRequestAddresses)       addr message (MsgAddresses)
-	getblockinvs message (MsgGetBlockInvs)  inv message (MsgInv)
-	inv message (MsgInv)                    getdata message (MsgGetData)
-	getdata message (MsgGetData)            block message (MsgBlock) -or-
-	                                        tx message (MsgTx) -or-
-	                                        notfound message (MsgNotFound)
-	ping message (MsgPing)                  pong message (MsgPong)
-
-Common Parameters
-
-There are several common parameters that arise when using this package to read
-and write kaspa messages. The following sections provide a quick overview of
-these parameters so the next sections can build on them.
-
-Protocol Version
-
-The protocol version should be negotiated with the remote peer at a higher
-level than this package via the version (MsgVersion) message exchange, however,
-this package provides the appmessage.ProtocolVersion constant which indicates the
-latest protocol version this package supports and is typically the value to use
-for all outbound connections before a potentially lower protocol version is
-negotiated.
-
-Kaspa Network
-
-The kaspa network is a magic number which is used to identify the start of a
-message and which kaspa network the message applies to. This package provides
-the following constants:
-
-    appmessage.Mainnet
-    appmessage.Testnet (Test network)
-    appmessage.Simnet  (Simulation test network)
-    appmessage.Devnet  (Development network)
-
-Determining Message Type
-
-As discussed in the kaspa message overview section, this package reads
-and writes kaspa messages using a generic interface named Message. In
-order to determine the actual concrete type of the message, use a type
-switch or type assertion. An example of a type switch follows:
-
-	// Assumes msg is already a valid concrete message such as one created
-	// via NewMsgVersion or read via ReadMessage.
-	switch msg := msg.(type) {
-	case *appmessage.MsgVersion:
-		// The message is a pointer to a MsgVersion struct.
-		fmt.Printf("Protocol version: %d", msg.ProtocolVersion)
-	case *appmessage.MsgBlock:
-		// The message is a pointer to a MsgBlock struct.
-		fmt.Printf("Number of tx in block: %d", msg.Header.TxnCount)
-	}
-
-Reading Messages
-
-In order to unmarshall kaspa messages from the appmessage, use the ReadMessage
-function. It accepts any io.Reader, but typically this will be a net.Conn to
-a remote node running a kaspa peer. Example syntax is:
-
-	// Reads and validates the next kaspa message from conn using the
-	// protocol version pver and the kaspa network kaspaNet. The returns
-	// are a appmessage.Message, a []byte which contains the unmarshalled
-	// raw payload, and a possible error.
-	msg, rawPayload, err := appmessage.ReadMessage(conn, pver, kaspaNet)
-	if err != nil {
-		// Log and handle the error
-	}
-
-Writing Messages
-
-In order to marshall kaspa messages to the appmessage, use the WriteMessage
-function. It accepts any io.Writer, but typically this will be a net.Conn to
-a remote node running a kaspa peer. Example syntax to request addresses
-from a remote peer is:
-
-	// Create a new getaddr kaspa message.
-	msg := appmessage.NewMsgRequestAddresses()
-
-	// Writes a kaspa message msg to conn using the protocol version
-	// pver, and the kaspa network kaspaNet. The return is a possible
-	// error.
-	err := appmessage.WriteMessage(conn, msg, pver, kaspaNet)
-	if err != nil {
-		// Log and handle the error
-	}
-
-Errors
-
-Errors returned by this package are either the raw errors provided by underlying
-calls to read/write from streams such as io.EOF, io.ErrUnexpectedEOF, and
-io.ErrShortWrite, or of type appmessage.MessageError. This allows the caller to
-differentiate between general IO errors and malformed messages through type
-assertions.
