The version string was added to the generator tag in v0.125.0 to address #11692, and was removed in v0.125.3 to address #12300 (comment). We should have closed #11692 as "won't fix".

I'll look into the zero pubdate problem.

The Date and Lastmod roll-up to section, taxonomy, and term pages. The PublishDate does not "roll-up".

I think the PublishDate should roll-up to the latest date before now(). If we rolled-up dates after now(), that would cause the section, taxonomy, or term page to not be published even if there's other descendant content.

Applicable to:

• Automatic section, taxonomy, and term pages
• Section, taxonomy, and term pages without Date and PublishDate

This isn't something new (i.e., same behavior in v0.122.0).

The test case below does not test for what should happen with publish dates greater than now() as described above.

func TestFoo(t *testing.T) {
	t.Parallel()

	files := `
-- hugo.toml --
disableKinds = ['home','rss','sitemap']
[taxonomies]
tag = 'tags'
-- layouts/_default/list.html --
Date: {{ .Date.Format "2006-01-02" }}
PublishDate: {{ .PublishDate.Format "2006-01-02" }}
Lastmod: {{ .Lastmod.Format "2006-01-02" }}
-- layouts/_default/single.html --
{{ .Title }}
-- content/s1/p1.md --
---
title: p1

`

	// Test without publishDate in front matter.
	b := hugolib.Test(t, files)

	b.AssertFileContent("public/s1/index.html", `
		Date: 2024-04-03
		PublishDate: 2024-04-03
		Lastmod: 2024-04-04
	`)

	b.AssertFileContent("public/tags/index.html", `
		Date: 2024-04-03
		PublishDate: 2024-04-03
		Lastmod: 2024-04-04
	`)

	b.AssertFileContent("public/tags/t1/index.html", `
		Date: 2024-04-03
		PublishDate: 2024-04-03
		Lastmod: 2024-04-04
	`)

	// Test with publishDate in front matter.
	files = strings.ReplaceAll(files, "lastmod", "publishDate")

	b = hugolib.Test(t, files)

	b.AssertFileContent("public/s1/index.html", `
		Date: 2024-04-03
		PublishDate: 2024-04-03
		Lastmod: 2024-04-03
	`)

	b.AssertFileContent("public/tags/index.html", `
		Date: 2024-04-03
		PublishDate: 2024-04-03
		Lastmod: 2024-04-03
	`)

	b.AssertFileContent("public/tags/t1/index.html", `
		Date: 2024-04-03
		PublishDate: 2024-04-03
		Lastmod: 2024-04-03
	`)
}

I think the PublishDate should roll-up to the latest date before now().

Yea, that sounds reasonable.

Is there a workaround that I could apply to get back the old behavior?

Or is there a chance to revert to the old behavior until a working fix is found?

Override the embedded RSS template, and change this line:

To:

<pubDate>{{ (or .PublishDate .Date).Format "Mon, 02 Jan 2006 15:04:05 -0700" | safeHTML }}</pubDate> 

If the page has a publication date, use that, else use the date.

Override the embedded RSS template [...]

Thanks, that worked.

For other readers: download the default rss.xml template to layouts/_default/rss.xml and change the pubDate line as shown above.
