Developer Sucker Punch has released their last update for Ghost of Tsushima as the studio presumably moves on with development of their next project.

Ghost of Tsushima Patch 2.18 marks the final update released for their open-world action-RPG. This update comes after about two years of patches, content, and support for the game. Word about this shift away from Ghost of Tsushima support came at the end of the patch 2.18 changelog.

Sucker Punch said the following:

While we aren’t actively working on any additional patches at the moment, we will continue to monitor feedback on the community-run Gotlegends subreddit and messages sent to @SuckerPunchProd on Twitter for any high priority bugs or issues that emerge. We want to say a huge THANK YOU to the entire community for the incredible amount of support and feedback we’ve gotten since launch. When Legends launched in October 2020, we never expected to have such an active community more than a year and a half later, and we could not be more thankful to everyone who has been with us on this journey!
Ghost of Tsushima was released for the PlayStation 4 in July 2020. A Director's Cut release then came out for the PlayStation 4 and PlayStation 5 on August 20, 2021. Sucker Punch even added in some multiplayer component to the game with the release of the Legends content in late 2020. A film based on the game is currently being worked on by Sony Pictures.

The rest of the 2.18 patch notes can be found below.

Patch 2.18

Patch 2.18 (2.018.000 on PS5) for Ghost of Tsushima Director’s Cut and the Legends standalone focuses on Legends items changes, bug fixes, and improvements as well as small single-player changes.

Patch 2.18 contains the following updates:

Legends
  • Fixed a bug where a teammate’s health could momentarily dip below zero, counting as a “death” in Custom Mode and Raid Trials that occasionally prevented the Hidden Heart cosmetic from unlocking

  • Shared Wounds no longer breaks Assassin out of the Vanish skill
