 - `Provider` (previously called `QueryHandle`) is extracted to its own package [purescript-cardano-provider](https://github.com/mlabs-haskell/purescript-cardano-provider) using module names in the format `Cardano.Provider.*` ([#1671](https://github.com/Plutonomicon/cardano-transaction-lib/pull/1671))
 - Switched from WebSocket to HTTP when interfacing with Ogmios. Note: Mempool functionality still uses WebSocket, as it requires a persistent connection to track state. ([#1575](https://github.com/Plutonomicon/cardano-transaction-lib/issues/1575))
 - Blockfrost provider has been extracted to a separate package using module names in the format `Cardano.Blockfrost.*` ([#1661](https://github.com/Plutonomicon/cardano-transaction-lib/issues/1661))
+- Kupo + Ogmios Provider has been extracted to a separate package [purescript-cardano-kupmios-provider](https://github.com/mlabs-haskell/purescript-cardano-kupmios-provider) using module names in the format `Cardano.Kupmios.*` ([#1662](https://github.com/Plutonomicon/cardano-transaction-lib/issues/1662))
+- Ogmios' mempool functionality has been extracted to a separate package [purescript-cardano-ogmios-mempool-provider](https://github.com/mlabs-haskell/purescript-cardano-ogmios-mempool-provider) using the module `Cardano.Ogmios.Mempool`. To use it, the user must create and manage the websocket connection (see [Test.Ctl.Testnet.Contract.OgmiosMempool](https://github.com/Plutonomicon/cardano-transaction-lib/blob/develop/test/Testnet/Contract/OgmiosMempool.purs))
