 Notable changes
 ===============
 
-Database cache memory increased
---------------------------------
-
-As a result of growth of the UTXO set, performance with the prior default
-database cache of 100 MiB has suffered.
-For this reason the default was changed to 300 MiB in this release.
-
-For nodes on low-memory systems, the database cache can be changed back to
-100 MiB (or to another value) by either:
-
-- Adding `dbcache=100` in bitcoin.conf
-- Changing it in the GUI under `Options → Size of database cache`
-
-Note that the database cache setting has the most performance impact
-during initial sync of a node, and when catching up after downtime.
-
-bitcoin-cli: arguments privacy
---------------------------------
-
-The RPC command line client gained a new argument, `-stdin`
-to read extra arguments from standard input, one per line until EOF/Ctrl-D.
-For example:
-
-    $ echo -e "mysecretcode\n120" | src/bitcoin-cli -stdin walletpassphrase
-
-It is recommended to use this for sensitive information such as wallet
-passphrases, as command-line arguments can usually be read from the process
-table by any user on the system.
-
-RPC low-level changes
-----------------------
-
-- `gettxoutsetinfo` UTXO hash (`hash_serialized`) has changed. There was a divergence between
-  32-bit and 64-bit platforms, and the txids were missing in the hashed data. This has been
-  fixed, but this means that the output will be different than from previous versions.
-
-- Full UTF-8 support in the RPC API. Non-ASCII characters in, for example,
-  wallet labels have always been malformed because they weren't taken into account
-  properly in JSON RPC processing. This is no longer the case. This also affects
-  the GUI debug console.
-
-C++11 and Python 3
--------------------
-
-Various code modernizations have been done. The Bitcoin Core code base has
-started using C++11. This means that a C++11-capable compiler is now needed for
-building. Effectively this means GCC 4.7 or higher, or Clang 3.3 or higher.
-
-When cross-compiling for a target that doesn't have C++11 libraries, configure with
-`./configure --enable-glibc-back-compat ... LDFLAGS=-static-libstdc++`.
-
-For running the functional tests in `qa/rpc-tests`, Python3.4 or higher is now
-required.
-
-Linux ARM builds
-------------------
-
-Due to popular request, Linux ARM builds have been added to the uploaded
-executables.
-
-The following extra files can be found in the download directory or torrent:
-
-- `bitcoin-${VERSION}-arm-linux-gnueabihf.tar.gz`: Linux binaries for the most
-  common 32-bit ARM architecture.
-- `bitcoin-${VERSION}-aarch64-linux-gnu.tar.gz`: Linux binaries for the most
-  common 64-bit ARM architecture.
-
-ARM builds are still experimental. If you have problems on a certain device or
-Linux distribution combination please report them on the bug tracker, it may be
-possible to resolve them.
-
-Note that Android is not considered ARM Linux in this context. The executables
-are not expected to work out of the box on Android.

 ### RPC and REST
 
-Asm script outputs replacements for OP_NOP2 and OP_NOP3
--------------------------------------------------------
-
-OP_NOP2 has been renamed to OP_CHECKLOCKTIMEVERIFY by [BIP 
-65](https://github.com/bitcoin/bips/blob/master/bip-0065.mediawiki)
-
-OP_NOP3 has been renamed to OP_CHECKSEQUENCEVERIFY by [BIP 
-112](https://github.com/bitcoin/bips/blob/master/bip-0112.mediawiki)
-
-The following outputs are affected by this change:
-- RPC `getrawtransaction` (in verbose mode)
-- RPC `decoderawtransaction`
-- RPC `decodescript`
-- REST `/rest/tx/` (JSON format)
-- REST `/rest/block/` (JSON format when including extended tx details)
-- `bitcoin-tx -json`
-
-New mempool information RPC calls
----------------------------------
-
-RPC calls have been added to output detailed statistics for individual mempool
-entries, as well as to calculate the in-mempool ancestors or descendants of a
-transaction: see `getmempoolentry`, `getmempoolancestors`, `getmempooldescendants`.
-
-### ZMQ
-
-Each ZMQ notification now contains an up-counting sequence number that allows
-listeners to detect lost notifications.
-The sequence number is always the last element in a multi-part ZMQ notification and
-therefore backward compatible.
-Each message type has its own counter.
-(https://github.com/bitcoin/bitcoin/pull/7762)
-
 ### Configuration and command-line options
 
 ### Block and transaction handling
 
 ### P2P protocol and network code
 
-The p2p alert system has been removed in #7692 and the 'alert' message is no longer supported.
-
-
-Fee filtering of invs (BIP 133)
-------------------------------------
-
-The optional new p2p message "feefilter" is implemented and the protocol
-version is bumped to 70013. Upon receiving a feefilter message from a peer,
-a node will not send invs for any transactions which do not meet the filter
-feerate. [BIP 133](https://github.com/bitcoin/bips/blob/master/bip-0133.mediawiki)
-
 ### Validation
 
 ### Build system
 
 ### Wallet
 
-Hierarchical Deterministic Key Generation
------------------------------------------
-Newly created wallets will use hierarchical deterministic key generation
-according to BIP32 (keypath m/0'/0'/k').
-Existing wallets will still use traditional key generation.
-
-Backups of HD wallets, regardless of when they have been created, can
-therefore be used to re-generate all possible private keys, even the
-ones which haven't already been generated during the time of the backup.
-
-HD key generation for new wallets can be disabled by `-usehd=0`. Keep in
-mind that this flag only has affect on newly created wallets.
-You can't disable HD key generation once you have created a HD wallet.
-
-There is no distinction between internal (change) and external keys.
