 ### Added
+- `contract` now exports the `DEFAULT_TIMEOUT` ([#984](https://github.com/stellar/js-stellar-sdk/pull/984)).
 - `contract.AssembledTransaction` now has:
-  - `toXDR` and `fromXDR` methods for serializing the transaction to and from XDR. Additionally, `contract.Client` now has a `txFromXDR`. These methods should be used in place of `AssembledTransaction.toJSON`, `AssembledTransaction.fromJSON`, and `Client.txFromJSON` for multi-auth signing. The JSON methods are now deprecated. **Note you must now call `simulate` on the transaction before the final `signAndSend` call after all required signatures are gathered when using the XDR methods.
-  -  a `restoreFootprint` method which accepts the `restorePreamble` returned when a simulation call fails due to some contract state that has expired. When invoking a contract function, one can now set `restore` to `true` in the `MethodOptions`. When enabled, a `restoreFootprint` transaction will be created and await signing when required.
-  - separate `sign` and `send` methods so that you can sign a transaction without sending it. You can continue to use `signAndSend` if you prefer.
+  - `toXDR` and `fromXDR` methods for serializing the transaction to and from XDR. These methods should be used in place of `AssembledTransaction.toJSON` and `AssembledTransaction.fromJSON`for multi-auth signing. The JSON methods are now deprecated. **Note:** you must now call `simulate` on the transaction before the final `signAndSend` call after all required signatures are gathered when using the XDR methods ([#977](https://github.com/stellar/js-stellar-sdk/pull/977)).
+  - a `restoreFootprint` method which accepts the `restorePreamble` returned when a simulation call fails due to some contract state that has expired. When invoking a contract function, one can now set `restore` to `true` in the `MethodOptions`. When enabled, a `restoreFootprint` transaction will be created and await signing when required ([#991](https://github.com/stellar/js-stellar-sdk/pull/991)).
+  - separate `sign` and `send` methods so that you can sign a transaction without sending it (`signAndSend` still works as before; [#922](https://github.com/stellar/js-stellar-sdk/pull/992)).
+- `contract.Client` now has a `txFromXDR` method which should be used in place of `txFromJSON` for multi-auth signing ([#977](https://github.com/stellar/js-stellar-sdk/pull/977)).
 
 ### Deprecated
-- In `contract.AssembledTransaction`, `toJSON` and `fromJSON` should be replaced with `toXDR` and
-`fromXDR`. Similarly, in `contract.Client`, `txFromJSON` should be replaced with `txFromXDR`.
+- In `contract.AssembledTransaction`, `toJSON` and `fromJSON` should be replaced with `toXDR` and `fromXDR`.
+- In `contract.Client`, `txFromJSON` should be replaced with `txFromXDR`.
 
 ### Fixed
-- Contract Client: if you edit an `AssembledTransaction` with `tx.raw = cloneFrom(tx.build)`, the `tx.simulationData` will now be updated correctly. `simulationData` is effectively a cache, and we now make sure we clear it when you re-simulate.
+- If you edit an `AssembledTransaction` with `tx.raw = cloneFrom(tx.build)`, the `tx.simulationData` will now be updated correctly ([#985](https://github.com/stellar/js-stellar-sdk/pull/985)).
