@pacoxu we can generate a CSV that can then be used in excel or google sheets. Also feel free to fork this gist to experiment!

I created one like this and updated status of some KEPs with @carlory.

  • We mainly update SIG-Node and SIG-Storage KEPs.

We have updated all keps that has no update after v1.26 now.

I divide it into 3 pages

  • not update after v1.22
  • updated between 1.23 and v1.29:
    • v1.23-v1.28
    • v1.29
  • updated after v1.30

After 1.33 there will be no alpha + enabled (WindowsHostNetwork was removed and we have a presubmit check now)

@BenTheElder we still have WindowsHostNetwork, defaulted to false and deprecated.

	WindowsHostNetwork: {
		{Version: version.MustParse("1.26"), Default: false, PreRelease: featuregate.Alpha},
		{Version: version.MustParse("1.33"), Default: false, PreRelease: featuregate.Deprecated},
	},

Er right, but not alpha+default enabled. Should've noticed that earlier scrolling this table :-)

Very neat use of the versioned FeatureGates info , something like this would be pretty cool on kubernetes.io

In the PR, the logic of this FG are totally removed: this is not like a traditional deprecation.

@pacoxu oof, lets take this to slack or the PR and follow up there

I'm also reaching out to the compat version folks about this table, @siyuanfoundation mentioned there's a tracking issue to implement something similar in the kubernetes docs using the feature gate yaml
