# Joint House #39: April 23th, 2024 Recording: [https://drive.google.com/file/d/12EnvdJA2iIvJAkjAObEAt8ofyrpPxhub/view?usp=sharing](https://drive.google.com/file/d/12EnvdJA2iIvJAkjAObEAt8ofyrpPxhub/view?usp=sharing) Slides: [April 23rd, joint house call slides](https://docs.google.com/presentation/d/13CccQIoN7Zc2YcE8tz9IgTO6EwukjYnrHwm8-BgTgjM/edit?usp=sharing) - Two proposals passed on [Voting Cycle #21](https://gov.optimism.io/t/voting-cycle-roundup-21/7967). - As season 5 is about to end, now is time to leave feedback: [S5 Feedback thread](https://gov.optimism.io/t/season-5-feedback-thread/7549) - We had Ben Jones talking about three different upgrades are coming in voting cycle #23A: - Governor upgrade: all upgrades that are governor contracts, will go through a token vote. It will be a quite small upgrade; bug fixes, UX improvements, etc. - Fault proofs upgrade: fault proofs will be soon out to mainnet. - Modification to the pause structure: will be splitted into two proposals. The other one is effectively a role change in the smart contracts system, right now the Optimism Foundation plays the guardian role for the OP Mainnet and this is effectively the ability to pause the system in the event of emergency fixes, being too much control for the foundation to have directly, the second upgrade along with fault proofs, will basically shift the fundamental ability to pause over to the Security Council. The Security Council will be able to unilaterally revoke the right from the Foundation to permanently pause the system in case it is misused. - More information will be out soon! - [Retro Funding 4: Onchain Builders](https://gov.optimism.io/t/retro-funding-4-onchain-builders-round-details/7988) was announced: We are holding a Speed-Networking event on Zoom this Friday 26th at 17:00 UTC - 13:00 ET - 19:00 CET, make sure to be there! --- _[View the full topic](https://gov.optimism.io/t/optimism-community-call-recaps-recordings-thread/6937)._
