 - Remove dependencies on the `chrono` crate.
   ([#1030](https://github.com/informalsystems/tendermint-rs/issues/1030))
 - `[tendermint]` Improve `tendermint::Time`
-  ([#1030](https://github.com/informalsystems/tendermint-rs/issues/1030)):
+  ([#1036](https://github.com/informalsystems/tendermint-rs/issues/1036),
+   revised by [#1048](https://github.com/informalsystems/tendermint-rs/pull/1048)):
   * Restrict the validity range of `Time` to dates with years in the range
     1-9999, to match the specification of protobuf message `Timestamp`.
     Add an `ErrorDetail` variant `DateOutOfRange` to report when this
     restriction is not met.
   * Added a conversion to, and a fallible conversion from,
     `OffsetDateTime` of the `time` crate.
-  * Added `Time` methods `checked_add` and `checked_sub`.
