+
+## Unreleased
+- [808] Adopt lightclient-protocol v0.4.0
+
+### Added 
+### Changed
+- zaino-proto now references v0.4.0 files
+### Removed
+- `
+
+### Deprecated
+- `zaino-fetch::chain:to_compact` in favor of `to_compact_tx` which takes an 
+  optional height and a `PoolTypeFilter` (see zaino-proto changes)
+- 
+## [v0.4.0] - 2025-12-03
+
+### Added
+- `compact_formats.CompactTxIn`
+- `compact_formats.TxOut`
+- `service.PoolType`
+- `service.LightdInfo` has added fields `upgradeName`, `upgradeHeight`, and
+  `lightwalletProtocolVersion`
+- `compact_formats.CompactTx` has added fields `vin` and `vout`,
+  which may be used to represent transparent transaction input and output data.
+- `service.BlockRange` has added field `poolTypes`, which allows
+  the caller of service methods that take this type as input to cause returned
+  data to be filtered to include information only for the specified protocols.
+  For backwards compatibility, when this field is set the default (empty) value,
+  servers should return Sapling and Orchard data. This field is to be ignored
+  when the type is used as part of a `service.TransparentAddressBlockFilter`.
+
+### Changed
+- The `hash` field of `compact_formats.CompactTx` has been renamed to `txid`.
+  This is a serialization-compatible clarification, as the index of this field
+  in the .proto type does not change.
+- `service.Exclude` has been renamed to `service.GetMempoolTxRequest` and has
+  an added `poolTypes` field, which allows the caller of this method to specify
+  which pools the resulting `CompactTx` values should contain data for.
+
+### Deprecated
+- `service.CompactTxStreamer`:
+    - The `GetBlockNullifiers` and `GetBlockRangeNullifiers` methods are
+      deprecated.
+- `zaino_fetch::FullTransaction::to_compact` deprecated in favor of `to_compact_tx` which includes
+  an optional for index to explicitly specify that the transaction is in the mempool and has no
+  index and `Vec<PoolType>` to filter pool types according to the transparent data changes of
+  lightclient-protocol v0.4.0
+- `zaino_fetch::chain::Block::to_compact` deprecated in favor of `to_compact_block` allowing callers
+  to specify `PoolTypeFilter` to filter pools that are included into the compact block according to
+  lightclient-protocol v0.4.0
+- `zaino_fetch::chain::Transaction::to_compact` deprecated in favor of `to_compact_tx` allowing callers
+  to specify `PoolTypFilter` to filter pools that are included into the compact transaction according
+  to lightclient-protocol v0.4.0.
+
+## [v0.3.6] - 2025-05-20
+
+### Added
+- `service.LightdInfo` has added field `donationAddress`
+- `service.CompactTxStreamer.GetTaddressTransactions`. This duplicates
+  the `GetTaddressTxids` method, but is more accurately named.
+
+### Deprecated
+- `service.CompactTxStreamer.GetTaddressTxids`. Use `GetTaddressTransactions`
+  instead.
+
+## [v0.3.5] - 2023-07-03

+- `service.CompactTxStreamer.GetBlockRangeNullifiers`
+- `service.CompactTxStreamer.SubtreeRoots`
+
+### Changed
+- `compact_formats.CompactBlock` has added field `chainMetadata`
+- `compact_formats.CompactSaplingOutput.epk` has been renamed to `ephemeralKey`
+
+## [v0.3.4] - UNKNOWN
