 Version 3.5.0 is not yet released.

+### Breaking changes in 3.5.0
+
+- The `XChainBridge` amendment and its ledger entries and transactions are removed. `XChainBridge` and `fixXChainRewardRounding` are now obsolete and can no longer be voted for; neither was ever enabled on Mainnet. `ledger_entry` no longer accepts `bridge`, `xchain_owned_claim_id`, or `xchain_owned_create_account_claim_id`; `account_objects` no longer accepts those values in `type`; and `server_definitions` no longer lists the removed ledger entry types, transaction types, fields, and the `XChainBridge` serialized type.
+- `subscribe` (`ledger` stream): The deprecated `fee_ref` field has been removed unconditionally from both the `subscribe` response and the `ledgerClosed` stream messages. It was previously only omitted when the `XRPFees` amendment was enabled; that amendment has now been retired, so the field is never returned. This applies to all API versions.
+
 ### Additions in 3.5.0

 - `subscribe`, `unsubscribe`: Added an optional `mpt_issuances` request field, an array of MPT issuance IDs (hex strings). Subscribers receive the same `transaction` message as the `transactions` stream for each validated transaction whose metadata affects a subscribed issuance. MPT issuance subscriptions count toward the per-connection subscription limit. An empty array, a non-array value, or an invalid ID returns `invalidParams`. ([#5671](https://github.com/XRPLF/rippled/pull/5671))

 - `account_currencies`, `account_nfts`, `account_offers`: A request with more than one problem may now report a different one of them. An invalid `ledger_hash` or `ledger_index` is reported before an invalid or missing `account`. An invalid `limit` or `marker` is reported before `lgrNotFound` or `actNotFound`, and for `account_offers` also before `actMalformed`. A request with a single problem returns the same error as before. [#8561](https://github.com/XRPLF/rippled/pull/8561)
 - `deposit_authorized`: A `credentials` entry that is all zeros (for example `"0"` or 64 `0` characters) now returns a `badCredentials` error instead of looking up a credential that can never exist.
 - `account_info`, `account_lines`, `account_channels`: A request with more than one problem may now report a different one of them. An invalid `ledger_hash` or `ledger_index` is reported before a missing or invalid `account`, or `ident` for `account_info`. For `account_lines`, a `peer` that is not a string, or an invalid `limit` or `marker`, is reported before `lgrNotFound`, `actNotFound` or a malformed `account`, and an invalid `limit` or `marker` also before a malformed `peer`. For `account_channels`, a malformed `account` is reported before `lgrNotFound`, and an invalid `destination_account`, `limit` or `marker` before `lgrNotFound` or `actNotFound`.

For `deposit_authorized`, an invalid `credentials` array is reported before `lgrNotFound`, `srcActNotFound`, `dstActNotFound` or `badCredentials`.

-// This is a special transaction used for creating accounts through a

-// transaction, we use a different mechanism: the accounts must be claimed on
-// the destination chain in the same order that the `XChainCreateAccountCommit`
-// transactions occurred on the source chain.
-//
-// This transaction can only be used for XRP to XRP bridges.
-//
-// IMPORTANT: This transaction should only be enabled if the witness
-// attestations will be reliably delivered to the destination chain. If the
-// signatures are not delivered (for example, the chain relies on user wallets
-// to collect signatures) then account creation would be blocked for all
-// transactions that happened after the one waiting on attestations. This could
-// be used maliciously. To disable this transaction on XRP to XRP bridges, the
-// bridge's `MinAccountCreateAmount` should not be present.
-//
-// Note: If this account already exists, the XRP is transferred to the existing
-// account. However, note that unlike the `XChainCommit` transaction, there is
-// no error handling mechanism. If the claim transaction fails, there is no
-// mechanism for refunds. The funds are permanently lost. This transaction
-// should still only be used for account creation.
