-mempool.dat compatibility
-========================
-
-The `mempool.dat` file created by -persistmempool or the savemempool RPC will
-be written in a new format, which 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.

-libbitcoinconsensus
-========================
-
-This library is deprecated and will be removed for v28.
-
-It has existed for nearly 10 years with very little known uptake or impact. It
-has become a maintenance burden.
-
-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.
-
-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.
