Subject: [PATCH 01/96] [REST] getutxos REST command (based on Bip64)

has parts of @mhearn #4351
* allows querying the utxos over REST
* same binary input and outputs as mentioned in Bip64
* input format = output format
* various rpc/rest regtests

 Risks
 -------------
 Running a webbrowser on the same node with a REST enabled bitcoind can be a risk. Accessing prepared XSS websites could read out tx/block data of your node by placing links like `<script src="http://127.0.0.1:8332/rest/tx/1234567890.json">` which might break the nodes privacy.

Subject: [PATCH 11/96] Replace mruset setAddrKnown with CRollingBloomFilter
 addrKnown

Use a probabilistic bloom filter to keep track of which addresses
we think we have given our peers, instead of a list.

This uses much less memory, at the cost of sometimes failing to
relay an address to a peer-- worst case if the bloom filter happens
to be as full as it gets, 1-in-1,000.

Measured memory usage of a full mruset setAddrKnown: 650Kbytes
Constant memory usage of CRollingBloomFilter addrKnown: 37Kbytes.

This will also help heap fragmentation, because the 37K of storage
is allocated when a CNode is created (when a connection to a peer
is established) and then there is no per-item-remembered memory
allocation.

I plan on testing by restarting a full node with an empty peers.dat,
running a while with -debug=addrman and -debug=net, and making sure
that the 'addr' message traffic out is reasonable.
(suggestions for better tests welcome)

Subject: [PATCH 25/96] Fix potential race conditions in p2p testing framework

Previously, each NodeConnCB had its own lock to synchronize data structures
used by the testing thread and the networking thread, and NodeConn provided a
separate additional lock for synchronizing access to each send buffer.  This
commit replaces those locks with a single global lock (mininode_lock) that we
use to synchronize access to all data structures shared by the two threads.

Updates comptool and maxblocksinflight to use the new synchronization
semantics, eliminating previous race conditions within comptool, and re-enables
invalidblockrequest.py in travis.

Subject: [PATCH 32/96] Update key.cpp to use new libsecp256k1

libsecp256k1's API changed, so update key.cpp to use it.

Libsecp256k1 now has explicit context objects, which makes it completely thread-safe.
In turn, keep an explicit context object in key.cpp, which is explicitly initialized
destroyed. This is not really pretty now, but it's more efficient than the static
initialized object in key.cpp (which made for example bitcoin-tx slow, as for most of
its calls, libsecp256k1 wasn't actually needed).

This also brings in the new blinding support in libsecp256k1. By passing in a random
seed, temporary variables during the elliptic curve computations are altered, in such
a way that if an attacker does not know the blind, observing the internal operations
leaks less information about the keys used. This was implemented by Greg Maxwell.

Subject: [PATCH 35/96] Show an init message while activating best chain

Connecting the chain can take quite a while.
All the while it is still showing `Loading wallet...`.
Add an init message to inform the user what is happening.

 comment

The prune help message was broken in nonsensical parts. Merge it into

Subject: [PATCH 40/96] QA: add RPC tests for error reporting of
 "signrawtransaction"

Tests error reporting of transaction signing via RPC call "signrawtransaction".

Expected results:

Test 1: create and sign a valid raw transaction with one input:
- 1) The transaction has a complete set of signatures
- 2) No script verification error occurred

Test 2: create and sign a raw transaction with one valid, one invalid and one missing input script:
- 3) The transaction has no complete set of signatures
- 4) Two script verification errors occurred
- 5) Script verification errors have certain properties ("txid", "vout", "scriptSig", "sequence", "error")
- 6) The verification errors refer to the invalid (vin 1) and missing input (vin 2)

Subject: [PATCH 54/96] Avoid crash on start in TestBlockValidity with gen=1.

When the internal miner is enabled at the start of a new node, there
 is an near instant assert in TestBlockValidity because its attempting
 to mine a block before the top checkpoint.

Also avoids a data race around vNodes.

Subject: [PATCH 59/96] Create new BlockPolicyEstimator for fee estimates

This class groups transactions that have been confirmed in blocks into buckets, based on either their fee or their priority.  Then for each bucket, the class calculates what percentage of the transactions were confirmed within various numbers of blocks.  It does this by keeping an exponentially decaying moving history for each bucket and confirm block count of the percentage of transactions in that bucket that were confirmed within that number of blocks.

-Eliminate txs which didn't have all inputs available at entry from fee/pri calcs

-Add dynamic breakpoints and tracking of confirmation delays in mempool transactions

-Remove old CMinerPolicyEstimator and CBlockAverage code

-New smartfees.py

-Pass a flag to the estimation code, using IsInitialBlockDownload as a proxy for when we are still catching up and we shouldn't be counting how many blocks it takes for transactions to be included.

-Add a policyestimator unit test

+/** \class CBlockPolicyEstimator
+ * The BlockPolicyEstimator is used for estimating the fee or priority needed
+ * for a transaction to be included in a block within a certain number of
+ * blocks.
+ *
+ * At a high level the algorithm works by grouping transactions into buckets
+ * based on having similar priorities or fees and then tracking how long it
+ * takes transactions in the various buckets to be mined.  It operates under
+ * the assumption that in general transactions of higher fee/priority will be
+ * included in blocks before transactions of lower fee/priority.   So for
+ * example if you wanted to know what fee you should put on a transaction to
+ * be included in a block within the next 5 blocks, you would start by looking
+ * at the bucket with with the highest fee transactions and verifying that a
+ * sufficiently high percentage of them were confirmed within 5 blocks and
+ * then you would look at the next highest fee bucket, and so on, stopping at
+ * the last bucket to pass the test.   The average fee of transactions in this
+ * bucket will give you an indication of the lowest fee you can put on a
+ * transaction and still have a sufficiently high chance of being confirmed
+ * within your desired 5 blocks.
+ *
+ * When a transaction enters the mempool or is included within a block we
+ * decide whether it can be used as a data point for fee estimation, priority
+ * estimation or neither.  If the value of exactly one of those properties was
+ * below the required minimum it can be used to estimate the other.  In
+ * addition, if a priori our estimation code would indicate that the
+ * transaction would be much more quickly included in a block because of one
+ * of the properties compared to the other, we can also decide to use it as
+ * an estimate for that property.
+ *
+ * Here is a brief description of the implementation for fee estimation.
+ * When a transaction that counts for fee estimation enters the mempool, we
+ * track the height of the block chain at entry.  Whenever a block comes in,
+ * we count the number of transactions in each bucket and the total amount of fee
+ * paid in each bucket. Then we calculate how many blocks Y it took each
+ * transaction to be mined and we track an array of counters in each bucket
+ * for how long it to took transactions to get confirmed from 1 to a max of 25
+ * and we increment all the counters from Y up to 25. This is because for any
+ * number Z>=Y the transaction was successfully mined within Z blocks.  We
+ * want to save a history of this information, so at any time we have a
+ * counter of the total number of transactions that happened in a given fee
+ * bucket and the total number that were confirmed in each number 1-25 blocks
+ * or less for any bucket.   We save this history by keeping an exponentially
+ * decaying moving average of each one of these stats.  Furthermore we also
+ * keep track of the number unmined (in mempool) transactions in each bucket
+ * and for how many blocks they have been outstanding and use that to increase
+ * the number of transactions we've seen in that fee bucket when calculating
+ * an estimate for any number of confirmations below the number of blocks
+ * they've been outstanding.
+ */
+
+/**
+ * We will instantiate two instances of this class, one to track transactions
+ * that were included in a block due to fee, and one for tx's included due to
+ * priority.  We will lump transactions into a bucket according to their approximate
+ * fee or priority and then track how long it took for those txs to be included in a block
+ *
+ * The tracking of unconfirmed (mempool) transactions is completely independent of the
+ * historical tracking of transactions that have been confirmed in a block.

Subject: [PATCH 76/96] depends: sanity-check sources and cached builds

In some cases (Travis), sources and build caches may be moved around in-between
builds, and we can't necessarily trust that everything is still intact.

This introduces pre-build checks that verify against stashed checksums.

Note that this will cause all sources to be re-downloaded, since cached sources
weren't trustworthy before this.

This assertion will occur any time that the client quits without
shutting down properly due to an error condition. As the user will
report this error instead of the error that was the root cause, it is
better to remove it.

 Each package is required to define at least these variables:
-  $(package)_version:
+
+    $(package)_version:
     Version of the upstream library or program. If there is no version, a
     placeholder such as 1.0 can be used.
-  $(package)_download_path:

     Location of the upstream source, without the file-name. Usually http or
     ftp.
-  $(package)_file_name:

+## Build Variables:
 After defining the main identifiers, build variables may be added or customized
 before running the build commands. They should be added to a function called
 $(package)_set_vars. For example:

-endef

 Most variables can be prefixed with the host, architecture, or both, to make
 the modifications specific to that case. For example:

Subject: [PATCH 91/96] More robust CScheduler unit test

On a busy or slow system, the CScheduler unit test could fail because it
assumed all threads would be done after a couple of milliseconds.

Replace the hard-coded sleep with CScheduler stop() method that
will cleanly exit the servicing threads when all tasks are completely
finished.

+Bitcoin Core version 0.10.1 is now available from:
+
+  <https://bitcoin.org/bin/bitcoin-core-0.10.1/>
+
+This is a new minor version release, bringing bug fixes and translation 
+updates. It is recommended to upgrade to this version.
+
+Please report bugs using the issue tracker at github:
+
+  <https://github.com/bitcoin/bitcoin/issues>
+
+Upgrading and downgrading
+=========================
+
+How to Upgrade
+--------------
+
+If you are running an older version, shut it down. Wait until it has completely
+shut down (which might take a few minutes for older versions), then run the
+installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or
+bitcoind/bitcoin-qt (on Linux).
+
+Downgrade warning
+------------------
+
+Because release 0.10.0 and later makes use of headers-first synchronization and
+parallel block download (see further), the block files and databases are not
+backwards-compatible with pre-0.10 versions of Bitcoin Core or other software:
+
+* Blocks will be stored on disk out of order (in the order they are
+received, really), which makes it incompatible with some tools or
+other programs. Reindexing using earlier versions will also not work
+anymore as a result of this.
+
+* The block index database will now hold headers for which no block is
+stored on disk, which earlier versions won't support.
+
+If you want to be able to downgrade smoothly, make a backup of your entire data
+directory. Without this your node will need start syncing (or importing from
+bootstrap.dat) anew afterwards. It is possible that the data from a completely
+synchronised 0.10 node may be usable in older versions as-is, but this is not
+supported and may break as soon as the older version attempts to reindex.
+
+This does not affect wallet forward or backward compatibility.
+

+

+
+OpenSSL Warning
+================
+
+OpenSSL 1.0.0p / 1.0.1k was recently released and is being pushed out by
+various operating system maintainers. Review by Gregory Maxwell determined that
+this update is incompatible with the Bitcoin system and could lead to consensus
+forks.
+
+Bitcoin Core released binaries from https://bitcoin.org are unaffected,
+as are any built with the gitian deterministic build system.
+
+However, if you are running either
+
+- The Ubuntu PPA from https://launchpad.net/~bitcoin/+archive/ubuntu/bitcoin
+- A third-party or self-compiled Bitcoin Core
+
+upgrade to Bitcoin Core 0.9.4, which includes a workaround, **before** updating
+OpenSSL.
+
+The incompatibility is due to the OpenSSL update changing the
+behavior of ECDSA validation to reject any signature which is
+not encoded in a very rigid manner. This was a result of
+OpenSSL's change for CVE-2014-8275 "Certificate fingerprints
+can be modified".
+
+We are specifically aware of potential hard-forks due to signature
+encoding handling and had been hoping to close them via BIP62 in 0.10.
+BIP62's purpose is to improve transaction malleability handling and
+as a side effect rigidly defines the encoding for signatures, but the
+overall scope of BIP62 has made it take longer than we'd like to
+deploy.
+
+0.9.4 changelog
+================
+
+Validation:
+- `b8e81b7` consensus: guard against openssl's new strict DER checks
+- `60c51f1` fail immediately on an empty signature
+- `037bfef` Improve robustness of DER recoding code
+
+Command-line options:
+- `cd5164a` Make -proxy set all network types, avoiding a connect leak.
+
+P2P:
+- `bb424e4` Limit the number of new addressses to accumulate
+
+RPC:
+- `0a94661` Disable SSLv3 (in favor of TLS) for the RPC client and server.
+
+Build system:
+- `f047dfa` gitian: openssl-1.0.1i.tar.gz -> openssl-1.0.1k.tar.gz
+- `5b9f78d` build: Fix OSX build when using Homebrew and qt5
+- `ffab1dd` Keep symlinks when copying into .app bundle
+- `613247f` osx: fix signing to make Gatekeeper happy (again)
