-Notable changes
-===============
+### RPC
 
-libbitcoinconsensus
--------------------
+- #29869 rpc, bugfix: Enforce maximum value for setmocktime
 
-- libbitcoinconsensus is deprecated and will be removed for v28. This library has
-  existed for nearly 10 years with very little known uptake or impact. It has
-  become a maintenance burden.
+### Test
 
-  The underlying functionality does not change between versions, so any users of
-  the library can continue to use the final release indefinitely, with the
-  understanding that Taproot is its final consensus update.
+- #29892 test: Fix failing univalue float test
 
-  In the future, libbitcoinkernel will provide a much more useful API that is
-  aware of the UTXO set, and therefore be able to fully validate transactions and
-  blocks. (#29189)
+### Build
 
-mempool.dat compatibility
--------------------------
+- #29747 depends: fix mingw-w64 Qt DEBUG=1 build
 
-- The `mempool.dat` file created by -persistmempool or the savemempool RPC will
-  be written in a new format. This new format includes the XOR'ing of transaction
-  contents to mitigate issues where external programs (such as anti-virus) attempt
-  to interpret and potentially modify the file.
+### CI
 
-  This new format can not be read by previous software releases. To allow for a
-  downgrade, a temporary setting `-persistmempoolv1` has been added to fall back
-  to the legacy format. (#28207)
+- #29856 ci: Bump s390x to ubuntu:24.04
 
-P2P and network changes
------------------------
+### Misc
 
-- BIP324 v2 transport is now enabled by default. It remains possible to disable v2
-  by running with `-v2transport=0`. (#29347)
-- Manual connection options (`-connect`, `-addnode` and `-seednode`) will
-  now follow `-v2transport` to connect with v2 by default. They will retry with
-  v1 on failure. (#29058)
-
-- Network-adjusted time has been removed from consensus code. It is replaced
-  with (unadjusted) system time. The warning for a large median time offset
-  (70 minutes or more) is kept. This removes the implicit security assumption of
-  requiring an honest majority of outbound peers, and increases the importance
-  of the node operator ensuring their system time is (and stays) correct to not
-  fall out of consensus with the network. (#28956)
-
-Mempool Policy Changes
-----------------------
-
-- Opt-in Topologically Restricted Until Confirmation (TRUC) Transactions policy
-  (aka v3 transaction policy) is available for use on test networks when
-  `-acceptnonstdtxn=1` is set. By setting the transaction version number to 3, TRUC transactions
-  request the application of limits on spending of their unconfirmed outputs. These
-  restrictions simplify the assessment of incentive compatibility of accepting or
-  replacing TRUC transactions, thus ensuring any replacements are more profitable for
-  the node and making fee-bumping more reliable. TRUC transactions are currently
-  nonstandard and can only be used on test networks where the standardness rules are
-  relaxed or disabled (e.g. with `-acceptnonstdtxn=1`). (#28948)
-
-External Signing
-----------------
-
-- Support for external signing on Windows has been disabled. It will be re-enabled
-  once the underlying dependency (Boost Process), has been replaced with a different
-  library. (#28967)
-
-Updated RPCs
-------------
-
-- The addnode RPC now follows the `-v2transport` option (now on by default, see above) for making connections.
-  It remains possible to specify the transport type manually with the v2transport argument of addnode. (#29239)
-
-Build System
-------------
-
-- A C++20 capable compiler is now required to build Bitcoin Core. (#28349)
-- MacOS releases are configured to use the hardened runtime libraries (#29127)
-
-Wallet
-------
-
-- The CoinGrinder coin selection algorithm has been introduced to mitigate unnecessary
-  large input sets and lower transaction costs at high feerates. CoinGrinder
-  searches for the input set with minimal weight. Solutions found by
-  CoinGrinder will produce a change output. CoinGrinder is only active at
-  elevated feerates (default: 30+ sat/vB, based on `-consolidatefeerate`×3). (#27877)
-- The Branch And Bound coin selection algorithm will be disabled when the subtract fee
-  from outputs feature is used. (#28994)
-- If the birth time of a descriptor is detected to be later than the first transaction
-  involving that descriptor, the birth time will be reset to the earlier time. (#28920)
-
-Low-level changes
-=================
-
-Pruning
--------
-
-- When pruning during initial block download, more blocks will be pruned at each
-  flush in order to speed up the syncing of such nodes. (#20827)
-
-Init
-----
-
-- Various fixes to prevent issues where subsequent instances of Bitcoin Core would
-  result in deletion of files in use by an existing instance. (#28784, #28946)
-- Improved handling of empty `settings.json` files. (#29144)
+- #29691 Change Luke Dashjr seed to dashjr-list-of-p2p-nodes.us
