+=================
+
+- Previously `setban`, `addpeeraddress`, `walletcreatefundedpsbt`, methods
+  allowed non-boolean and non-null values to be passed as boolean parameters.
+  Any string, number, array, or object value that was passed would be treated
+  as false. After this change, passing any value except `true`, `false`, or
+  `null` now triggers a JSON value is not of expected type error. (#7666)

Subject: [PATCH 02/10] Merge bitcoin/bitcoin#23319: rpc: Return fee and
 prevout (utxos) to getrawtransaction

f86697163e5cdbc3bc4a65cfb7dbaa3d9eb602a9 rpc: Return fee and prevout(s) to getrawtransaction (Douglas Chimento)

Pull request description:

  Add fee response in BTC to getrawtransaction #23264

  ### For Reviewers

  * Verbose arg is now an int
  * Verbose = 2 includes a `fee` field and `prevout`
  * [./test/functional/rpc_rawtransaction.py](./test/functional/rpc_rawtransaction.py) contains a new test to validate fields of new verbosity 2 (not the values)

  ```

e6906fcf9e4d5692ead6c9bf5a2e11673315a1f5 rpc: Enable wallet import on pruned nodes (Aurèle Oulès)

Pull request description:

  Reopens #16037

  I have rebased the PR, addressed the comments of the original PR and added a functional test.

  > Before this change importwallet fails if any block is pruned. This PR makes it possible to importwallet if all required blocks aren't pruned. This is possible because the dump format includes key timestamps.

  For reviewers:
  `python test/functional/wallet_pruning.py --nocleanup` will generate a large blockchain (~700MB) that can be used to manually test wallet imports on a pruned node. Node0 is not pruned, while node1 is.

Subject: [PATCH 07/10] Merge bitcoin/bitcoin#26289: Use util::Result in for
 calculating mempool ancestors

5481f65849313ff947f38433b1ac28285a7f7694 mempool: add AssumeCalculateMemPoolAncestors helper function (stickies-v)
f911bdfff95eba3793fffaf71a31cc8bfc6f80c9 mempool: use util::Result for CalculateMemPoolAncestors (stickies-v)
66e028f7399b6511f9b73b1cef54b6a6ac38a024 mempool: use util::Result for CalculateAncestorsAndCheckLimits (stickies-v)

Pull request description:

  Upon reviewing the documentation for `CTxMemPool::CalculateMemPoolAncestors`, I noticed `setAncestors` was meant to be an `out` parameter but actually is an `in,out` parameter, as can be observed by adding `assert(setAncestors.empty());` as the first line in the function and running `make check`. This PR fixes this unexpected behaviour and introduces refactoring improvements to make intents and effects of the code more clear.

  ## Unexpected behaviour
  This behaviour occurs only in the package acceptance path, currently only triggered by `testmempoolaccept` and `submitpackage` RPCs.

  In `MemPoolAccept::AcceptMultipleTransactions()`, we first call `PreChecks()` and then `SubmitPackage()` with the same `Workspace ws` reference. `PreChecks` leaves `ws.m_ancestors` in a potentially non-empty state, before it is passed on to `MemPoolAccept::SubmitPackage`. `SubmitPackage` is the only place where `setAncestors` isn't guaranteed to be empty before calling `CalculateMemPoolAncestors`. The most straightforward fix is to just forcefully clear `setAncestors` at the beginning of CalculateMemPoolAncestors, which is done in the first bugfix commit.

  ## Improvements
  ### Return value instead of out-parameters
  This PR updates the function signatures for `CTxMemPool::CalculateMemPoolAncestors` and `CTxMemPool::CalculateAncestorsAndCheckLimits` to use a `util::Result` return type and eliminate both the `setAncestors` `in,out`-parameter as well as the error string. It simplifies the code and makes the intent and effects more explicit.

  ### Observability
  There are 7 instances where we currently call `CalculateMemPoolAncestors` without actually checking if the function succeeded because we assume that it can't fail, such as in [miner.cpp](https://github.com/bitcoin/bitcoin/blob/69b10212ea5370606c7a5aa500a70c36b4cbb58f/src/node/miner.cpp#L399). This PR adds a new wrapper `AssumeCalculateMemPoolAncestors` function that logs such unexpected failures, or in case of debug builds even halts the program. It's not crucial to the objective, more of an observability improvement that seems sensible to add on here.

Subject: [PATCH 08/10] Merge bitcoin/bitcoin#19909: refactor: Remove unused
 CTxMemPool::clear() helper

fa818e103c0ddb515f29ae9ce8de44931e12e69e txmempool: Remove unused clear() member function (MarcoFalke)

Pull request description:

  Seems odd to have code in Bitcoin Core that is unused.

  Moreover the function was broken (see https://github.com/bitcoin/bitcoin/pull/24145) and is brittle, as there is nothing that prevents similar bugs from re-appearing.

  Fix both issues by replacing it with C++11 member initializers.

Subject: [PATCH 09/10] Merge bitcoin/bitcoin#26598: contrib: remove builder
 keys

e6864fa157d75d8ae2b2f56620b019bde2355a24 contrib: remove builder keys (fanquake)

Pull request description:

  This has been superseded by adding a builder-keys/ directory in
  guix.sigs, where the presence of keys, and validity of signatures
  is checked. Preventing issues like missing keys or invalid signatures.

  New (or exisiting) Guix builders can add their key in the next PR
  they open adding attestations.

  Related to issues like #26566, #26563.

  Also follows up with the comment here: https://github.com/bitcoin/bitcoin/pull/26565#issuecomment-1326053939.

 MIN_STANDARD_TX_NONWITNESS_SIZE to 65 non-witness bytes

b2aa9e85289fc654106a890c35935e9c76c411fb Add release note for MIN_STANDARD_TX_NONWITNESS_SIZE relaxation (Greg Sanders)
8c5b3646b5afe8a61f5c66478d8e11f0d2ce5108 Relax MIN_STANDARD_TX_NONWITNESS_SIZE to 65 non-witness bytes (Greg Sanders)

Pull request description:

  Since the original fix was set to be a "reasonable" transaction to reduce allocations and the true motivation later revealed, it makes sense to relax this check to something more principled.

  There are more exotic transaction patterns that could take advantage of a relaxed requirement, such as 1 input, 1 output OP_RETURN to burn a utxo to fees for CPFP purposes when change isn't practical.

  Two changes could be accomplished:

  1) Anything not 64 bytes could be allowed

  2) Anything above 64 bytes could be allowed

  In the Great Consensus Cleanup, suggestion (2)
  was proposed as a consensus change, and is the simpler of the two suggestions. It would not allow an "empty" OP_RETURN but would reduce the required padding from 22 bytes to 5.

  The functional test is also modified to test the actual case
  we care about: 64 bytes
