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.
