Chiado schedule

• Slot 15171584 ts 1741254220 UTC Thu 06/03/2025, 09:43:40

The (TENTATIVE) Mainnet schedule is:

• Slot 20905984 ts 1743523260 UTC Tue 01/04/2025, 16:01:00

It's one week before Ethereum mainnet, such that it's easier to have a single release for both mainnet forks.

Note that the config for Gnosis Pectra has some modified values

Name	Ethereum spec	Gnosis spec
MAX_PER_EPOCH_ACTIVATION_EXIT_CHURN_LIMIT	256000000000	64000000000
MAX_BLOBS_PER_BLOCK_ELECTRA	9	2
BLOB_SIDECAR_SUBNET_COUNT_ELECTRA	9	2
MAX_REQUEST_BLOB_SIDECARS_ELECTRA	1152	256

Thanks Lion for detailing the config diff, I am not sure we plan to cut another minor release before 06/03 but could cut a patch release or alternatively people run from unstable branch.

@philknows wdyt?

If we stick to our regular release schedule, we should cut v1.28.0-rc.0 by the end of next week for testing over that weekend, which would make v1.28.0 released as early as Tuesday 04/03/2025 assuming no issues. If this is too long of a wait and doesn't give operators enough upgrade time @dapplion, we can easily cut v1.27.1 with Chiado configs.

Personally, I would avoid putting Gnosis mainnet in just because Pectra Ethereum mainnet is still tentative too. But can be done at the same time if that's what you want.
