-Block file pruning
+Example header
 ----------------------
 
-This release supports running a fully validating node without maintaining a copy 
-of the raw block and undo data on disk. To recap, there are four types of data 
-related to the blockchain in the bitcoin system: the raw blocks as received over 
-the network (blk???.dat), the undo data (rev???.dat), the block index and the 
-UTXO set (both LevelDB databases). The databases are built from the raw data.
+Example content.
 
-Block pruning allows Bitcoin Core to delete the raw block and undo data once 
-it's been validated and used to build the databases. At that point, the raw data 
-is used only to relay blocks to other nodes, to handle reorganizations, to look 
-up old transactions (if -txindex is enabled or via the RPC/REST interfaces), or 
-for rescanning the wallet. The block index continues to hold the metadata about 
-all blocks in the blockchain.
-
-The user specifies how much space to allot for block & undo files. The minimum 
-allowed is 550MB. Note that this is in addition to whatever is required for the 
-block index and UTXO databases. The minimum was chosen so that Bitcoin Core will 
-be able to maintain at least 288 blocks on disk (two days worth of blocks at 10 
-minutes per block). In rare instances it is possible that the amount of space 
-used will exceed the pruning target in order to keep the required last 288 
-blocks on disk.
-
-Block pruning works during initial sync in the same way as during steady state, 
-by deleting block files "as you go" whenever disk space is allocated. Thus, if 
-the user specifies 550MB, once that level is reached the program will begin 
-deleting the oldest block and undo files, while continuing to download the 
-blockchain.
-
-For now, block pruning disables block relay.  In the future, nodes with block 
-pruning will at a minimum relay "new" blocks, meaning blocks that extend their 
-active chain. 
-
-Block pruning is currently incompatible with running a wallet due to the fact 
-that block data is used for rescanning the wallet and importing keys or 
-addresses (which require a rescan.) However, running the wallet with block 
-pruning will be supported in the near future, subject to those limitations.
-
-Block pruning is also incompatible with -txindex and will automatically disable 
-it.
-
-Once you have pruned blocks, going back to unpruned state requires 
-re-downloading the entire blockchain. To do this, re-start the node with 
--reindex. Note also that any problem that would cause a user to reindex (e.g., 
-disk corruption) will cause a pruned node to redownload the entire blockchain. 
-Finally, note that when a pruned node reindexes, it will delete any blk???.dat 
-and rev???.dat files in the data directory prior to restarting the download.
-
-To enable block pruning on the command line:
-
-- `-prune=N`: where N is the number of MB to allot for raw block & undo data.
-
-Modified RPC calls:
-
-- `getblockchaininfo` now includes whether we are in pruned mode or not.
-- `getblock` will check if the block's data has been pruned and if so, return an 
-error.
-- `getrawtransaction` will no longer be able to locate a transaction that has a 
-UTXO but where its block file has been pruned. 
-
-Pruning is disabled by default.
-
-Big endian support
---------------------
-
-Experimental support for big-endian CPU architectures was added in this
-release. This has been tested on at least MIPS and PPC hosts. The build
-system will automatically detect the endianness of the target.
-
-Memory usage optimization
---------------------------
-
-There have been many changes in this release to reduce the default memory usage
-of a node, among which:
-
-- Accurate UTXO cache size accounting (#6102); this makes the option `-dbcache`
-  precise, where is did a gross underestimation of memory usage before
-- Reduce size of per-peer data structure (#6064 and others); this increases the
-  number of connections that can be supported with the same amount of memory
-- Reduce the number of threads (#5964, #5679); lowers the amount of (esp.
-  virtual) memory needed
-
-Privacy: Disable wallet transaction broadcast
-----------------------------------------------
-
-This release adds an option `-walletbroadcast=0` to prevent automatic
-transaction broadcast and rebroadcast (#5951). This option allows separating
-transaction submission from the node functionality.
-
-Making use of this, third-party scripts can be written to take care of
-transaction (re)broadcast:
-
-- Send the transaction as normal, either through RPC or the GUI
-- Retrieve the transaction data through RPC using `gettransaction` (NOT
-  `getrawtransaction`). The `hex` field of the result will contain the raw
-  hexadecimal representation of the transaction
-- The transaction can then be broadcasted through arbitrary mechanisms
-  supported by the script
-
-One such application is selective Tor usage, where the node runs on the normal
-internet but transactions are broadcasted over Tor.
-
-Privacy: Stream isolation for Tor
-----------------------------------
-
-This release adds functionality to create a new circuit for every peer
-connection, when the software is used with Tor. The new option,
-`-proxyrandomize`, is on by default.
-
-When enabled, every outgoing connection will (potentially) go through a
-different exit node. That significantly reduces the chance to get unlucky and
-pick a single exit node that is either malicious, or widely banned from the P2P
-network. This improves connection reliability as well as privacy, especially
-for the initial connections.
-
-**Important note:** If a non-Tor SOCKS5 proxy is configured that supports
-authentication, but doesn't require it, this change may cause it to reject
-connections. A user and password is sent where they weren't before. This setup
-is exceedingly rare, but in this case `-proxyrandomize=0` can be passed to
-disable the behavior.
