+*January 13th, 2021*
+
+This release notably updates the underlying CLI framework (`abscissa`) to version 0.6.0-beta.1,
+which now uses `clap` for parsing command line arguments. This substantially improves the UX of the CLI,
+by adding support for `--help` flags in subcommands and improving help and usage printouts.
+
+The `--version` option of the `create channel` subcommand has been renamed
+to `--channel-version`, with the old name still supported as an alias.
+Additionally, the `-h` short flag on many commands is now `-H` to avoid
+clashes with the clap-provided short flag for help.
+
+This release also improves the handling of account sequence mismatch errors,
+with a recovery mechanism to automatically retry or drop tx upon such errors.
+
+The relayer now also supports dynamic versions in channel open handshake (which is needed by Interchain Accounts), and enables full support for IBC v2.

+This is a pre-release which depends on forks of various Rust libraries.
+As such, it is advised to avoid depending on the `ibc` and `ibc-relayer` crates
+at version 0.8.0-pre.1.
+
+However, Hermes v0.8.0-pre.1 is considered stable and it is recommended for all
+users to update to this version.
+
+This release notably includes a new [`memo_prefix`][memo] configuration option
+for specifying a prefix to be include in the memo of each transaction submitted
+by Hermes.

+This is the final release of version 0.8.0, which now depends on the official releases of the `prost` and `tonic` crates.
+In addition to everything that's included in v0.8.0-pre.1, this release updates the minimum supported Rust version to 1.56,
+and contains various bug fixes and performance improvements which make the relayer more reliable.
+
+#### Notice for operators
+A new setting was added to the Hermes configuration: `max_block_time`.
+This setting specifies the maximum time per block for this chain.
+The block time together with the clock drift are added to the source drift to estimate
+the maximum clock drift when creating a client on this chain.
+For Cosmos-SDK chains a good approximation is `timeout_propose` + `timeout_commit`
