@acatangiu the CI wants me to update the AH Kusama spec version: https://github.com/polkadot-fellows/runtimes/actions/runs/9713954965/job/26811939881?pr=365 Not sure why because I didn't change anything in AH. The Snowbridge crates AH depends on was also not bumped. Should the BH spec version be |
| spec_version: 1_002_006, | ||
| spec_version: 1_002_008, |

if we massage the dependency bumps a bit we might get away without having to bump the AH spec versions, right @claravanstaden ?
I wouldn't release new AH runtime versions that bring nothing new

actually no, I'm wrong.
Even if this PR does not change anything for AHs, there have been other things merged in the meantime relevant to AHs.
So all good with bumping this.

@acatangiu thanks! I see CI is complaining about the Kusama relay version too: https://github.com/polkadot-fellows/runtimes/actions/runs/9740656775/job/26878232348?pr=365
I bumped both the Polkadot and Kusama relay versions: b2a0b26
Is that OK?

yes, all good 👍 we have changelog entries for them too I see
|
@acatangiu I removed the P<>K and Snowbridge unstuck migrations, since they ran successfully. Is that OK? |
|
@acatangiu what is the process to update the benchmarks? I need to do that before we release. Can I run it manually? |
Actually, there is no process yet :), but there is some ongoing work on the bot or process #128 by @mordamax. You can do it by yourself, here is a tutorial: https://github.com/polkadot-fellows/runtimes/blob/main/docs/weight-generation.md and you need just some machine/VM aligned with reference hardware. I did the last couple of weights regeneration on my dedicated machine, so I can also do it for you here, just let me know which pallets do you need and I can create PR to this PR. |

@bkontur thank you for the tips! I would appreciate you helping out since I don't have the required hardware ready off-hand. I need new weights for these two pallets:
Thanks again! <3 |

Upgrades Snowbridge to have a much more cost effective Ethereum light client. In the current light client in production, all Ethereum execution headers are stored, whether they contain a transfer message or not. This PR upgrades Snowbridge to not store execution headers at all, but provide the execution header proof alongside a message. Ethereum beacon headers are still stored, to track finalized headers and do ancestry proofs.
