-- `gettxspendingprevout` has 2 new optional arguments: `mempool_only` and `return_spending_tx`.
-  If `mempool_only` is true it will limit scans to the mempool even if `txospenderindex` is available.
-  If `return_spending_tx` is true, the full spending tx will be returned.
-  In addition if `txospenderindex` is available and a confirmed spending transaction is found,

-P2P and network changes
------------------------
-
-- Normally local transactions are broadcast to all connected peers with
-  which we do transaction relay. Now, for the `sendrawtransaction` RPC
-  this behavior can be changed to only do the broadcast via the Tor or
-  I2P networks. A new boolean option `-privatebroadcast` has been added
-  to enable this behavior. This improves the privacy of the transaction
-  originator in two aspects:
-  1. Their IP address (and thus geolocation) is never known to the
-     recipients.
-  2. If the originator sends two otherwise unrelated transactions, they
-     will not be linkable. This is because a separate connection is used
-     for broadcasting each transaction. (#29415)
-
-- New RPCs have been added to introspect and control private broadcast:
-  `getprivatebroadcastinfo` reports transactions currently being privately
-  broadcast, and `abortprivatebroadcast` removes matching
-  transactions from the private broadcast queue.

-RPC and Startup Option
----
-The `-paytxfee` startup option and the `settxfee` RPC are now deleted after being deprecated in Bitcoin Core 30.0. They used to allow the user to set a static fee rate for wallet transactions, which could potentially lead to overpaying or underpaying. Users should instead rely on fee estimation or specify a fee rate per transaction using the `fee_rate` argument in RPCs such as `fundrawtransaction`, `sendtoaddress`, `send`, `sendall`, and `sendmany`.

-Fee Estimation
-========================
-
-- The Bitcoin Core fee estimator minimum fee rate bucket was updated from **1 sat/vB** to **0.1 sat/vB**,
-  which matches the node’s default `minrelayfee`.
-  This means that for a given confirmation target, if a sub-1 sat/vB fee rate bucket is the minimum tracked
-  with sufficient data, its average value will be returned as the fee rate estimate.
-
-- Note: Restarting a node with this change invalidates previously saved estimates in `fee_estimates.dat`, the fee estimator will start tracking fresh stats.

-Mempool
-=======
-
-The mempool has been reimplemented with a new design ("cluster mempool"), to
-facilitate better decision-making when constructing block templates, evicting
-transactions, relaying transactions, and validating replacement transactions
-(RBF). Most changes should be transparent to users, but some behavior changes
-are noted:
-
-- The mempool no longer enforces ancestor or descendant size/count limits.
-  Instead, two new default policy limits are introduced governing connected
-  components, or clusters, in the mempool, limiting clusters to 64 transactions
-  and up to 101 kB in virtual size.  Transactions are considered to be in the
-  same cluster if they are connected to each other via any combination of
-  parent/child relationships in the mempool. These limits can be overridden
-  using command line arguments; see the extended help (`-help-debug`)
-  for more information.
-
-- Within the mempool, transactions are ordered based on the feerate at which
-  they are expected to be mined, which takes into account the full set, or
-  "chunk", of transactions that would be included together (e.g., a parent and
-  its child, or more complicated subsets of transactions). This ordering is
-  utilized by the algorithms that implement transaction selection for
-  constructing block templates; eviction from the mempool when it is full; and
-  transaction relay announcements to peers.
-
-- The replace-by-fee validation logic has been updated so that transaction
-  replacements are only accepted if the resulting mempool's feerate diagram is
-  strictly better than before the replacement. This eliminates all known cases
-  of replacements occurring that make the mempool worse off, which was possible
-  under previous RBF rules. For singleton transactions (that are in clusters by
-  themselves) it's sufficient for a replacement to have a higher fee and
-  feerate than the original. See
-  [delvingbitcoin.org post](https://delvingbitcoin.org/t/an-overview-of-the-cluster-mempool-proposal/393#rbf-can-now-be-made-incentive-compatible-for-miners-11)
-  for more information.
-
-- Two new RPCs have been added: `getmempoolcluster` will provide the set of
-  transactions in the same cluster as the given transaction, along with the
-  ordering of those transactions and grouping into chunks; and
-  `getmempoolfeeratediagram` will return the feerate diagram of the entire
-  mempool.
-
-- Chunk size and chunk fees are now also included in the output of `getmempoolentry`.
-
-- The "CPFP Carveout" has been removed from the mempool logic. The CPFP carveout
-  allowed one additional child transaction to be added to a package that's already
-  at its descendant limit, but only if that child has exactly one ancestor
-  (the package's root) and is small (no larger than 10kvB). Nothing is allowed to
-  bypass the cluster count limit. It is expected that smart contracting use-cases
-  requiring similar functionality employ TRUC transactions and sibling eviction
-  instead going forward.

-`-asmap` requires explicit filename
------------------------------------
-
-In previous releases, if `-asmap` was specified without a filename, this would try to load an `ip_asn.map` data file. Now loading an asmap file requires an explicit filename like `-asmap=ip_asn.map`. This change was made to make the option easier to understand, because it was confusing for there to be a default filename not actually loaded by default (https://github.com/bitcoin/bitcoin/issues/33386). Also this change makes the option more future-proof, because in upcoming releases, specifying `-asmap` will load embedded asmap data instead of an external file (https://github.com/bitcoin/bitcoin/pull/28792).

-Notable IPC mining interface changes since the last release:
-- `Mining.createNewBlock` and `Mining.checkBlock` now require a `context` parameter.
-- `Mining.waitTipChanged` now has a default `timeout` (effectively infinite / `maxDouble`) if the client omits it.
-- `BlockTemplate.getCoinbaseTx()` now returns a structured `CoinbaseTx` instead of raw bytes.
-- Removed `BlockTemplate.getCoinbaseCommitment()` and `BlockTemplate.getWitnessCommitmentIndex()`.
-- Cap’n Proto default values were updated to match the corresponding C++ defaults for mining-related option structs (e.g. `BlockCreateOptions`, `BlockWaitOptions`, `BlockCheckOptions`).
