It can be considered optional from a Polkadot parachain builders perspective. The main purpose of this release is to fine-tune some OpenGov parameters on the Kusama runtime and remove the requirement for implicit approval chilling upon slash. ## Runtimes built on release v0.9.35 - **Kusama v9350** - **Westend v9350** # ⚠ PRs Related to Kusama Runtime ### Remove implicit approval chilling upon slash. PR: [https://github.com/paritytech/substrate/pull/12420](https://github.com/paritytech/substrate/pull/12420) **Why is this change interesting for builders?** [Chilling](https://wiki.polkadot.network/docs/learn-staking#chilling) is the process, when you want to take temporarily pause in staking, either as a nominator or validator. You can go through [How to Chill](https://wiki.polkadot.network/docs/maintain-guides-how-to-chill) to know more about this process. At the moment, chilling process is very restrictive. If a slash is canceled, the chilling is not. This has been a major pain point so far. The purpose of this PR is to protect nominators. Once the slash will be canceled, nominators will be reactivated. You can find the discussion [here](https://forum.polkadot.network/t/kusama-era-4543-slashing/1410/2). This PR adds relaxation to chilling process and removes restrictions on it. **Does this change have a related companion PR?** polkadot companion: [#6424](https://github.com/paritytech/polkadot/pull/6424) **Is there any related issue?** [#6835](https://github.com/paritytech/substrate/issues/6835) * * * ### OpenGov: Tweak parameters further PR: [https://github.com/paritytech/polkadot/pull/6416](https://github.com/paritytech/polkadot/pull/6416) **How this impacts our polkadot builders?** This PR should not affect you if you are not using [Open Gov](https://medium.com/polkadot-network/gov2-polkadots-next-generation-of-decentralised-governance-4d9ef657d11b) based governance system. At the moment. [OpenGov](https://medium.com/polkadot-network/gov2-polkadots-next-generation-of-decentralised-governance-4d9ef657d11b) is present only on Kusama. This PR includes some tweaks in parameters, which are related to preparation, confirmation and enactment delay, by considering real world secenarios.
