+Updated RPCs
+------------
+
+- Due to [BIP 350](https://github.com/bitcoin/bips/blob/master/bip-0350.mediawiki)
+ being implemented, behavior for all RPCs that accept addresses is changed when
+ a native witness version 1 (or higher) is passed. These now require a Bech32m
+ encoding instead of a Bech32 one, and Bech32m encoding will be used for such
+ addresses in RPC output as well. No version 1 addresses should be created
+ for mainnet until consensus rules are adopted that give them meaning
+ (e.g. through [BIP 341](https://github.com/bitcoin/bips/blob/master/bip-0341.mediawiki)).
+ Once that happens, Bech32m is expected to be used for them, so this shouldn't
+ affect any production systems, but may be observed on other networks where such
+ addresses already have meaning (like signet).
