š£ Octez version 23.0 has just been released!
Octez v23.0 includes the following changes:
š°š· **Seoul Protocol support.** This release introduces a new version ([V15](https://octez.tezos.com/docs/protocols/023_seoul.html#environment-version)) of the protocol environment. Octez version 23 is the first version compatible with all protocols that require this environment.
As a result, this version is the first compatible version with the [Seoul protocol proposal](https://research-development.nomadic-labs.com/seoul-announcement.html), which is about to enter [its promotion period](https://www.tezosagora.org/period/154).
**Octez-baker.** Starting from v23, the protocol independent octez-baker executable is released.
This new binary dynamically selects and launches the appropriate protocol-dependent baking client based on the active protocol.
The protocol-dependent baker clients, for instance `octez-baker-PsRiotum` or `octez-baker-PtSeouLo`, are still released, but will be deprecated in an upcoming version.
We encourage bakers to adopt the new `octez-baker` binary to simplify and future proof their deployments!
**Support for new protocol features.** Version 23 implements new client commands and RPC endpoints to support new features introduced by Seoul:
- Aggregated Attestations: v23 allows registering delegates with a tz4 addresses, as well as setting tz4 addresses as consensus and DAL companion keys. See [Aggregated Attestations: A Heads Up for Bakers](https://forum.tezosagora.org/t/aggregated-attestations-a-heads-up-for-bakers/6770) for further detail.
- Native Multisig Accounts: v23 enables creating and operating with native multisig accounts. See [Heads up! Native multisig accounts in protocol proposal](https://forum.tezosagora.org/t/heads-up-native-multisig-accounts-in-protocol-proposal-s/6805) to learn more on their usecases.
A full changelog and update instructions are available in the [version 23 release page](https://octez.tezos.com/docs/releases/version-23.html).
The Git tag is `octez-v23.0` and the corresponding commit hash is `dc9bed35`.
