[Bug] Unpublished blog posts are still displayed on the front-end

[paulaime]

Since last Grav update (v1.7.0-beta.5), on one of my Grav websites that's using the Mediator theme (customized by me), all the unpublished blog posts are still displayed on the front-end.

The header of a blog post is as follows:

---
title: 'Title of the blog post'
media_order: background.jpg
published: false
image: background.jpg
---

And the header of the parent file (default.md) is as follows:

---
title: 'Title of the website'
external_links:
    process: true
    title: false
    no_follow: true
    target: _blank
    mode: active
sitemap:
    changefreq: monthly
    priority: 1.03
content:
    items: '@self.children'
    order:
        by: date
        dir: desc
    limit: 4
    pagination: true
feed:
    description: 'Sample blog description'
    limit: 10
pagination: true

But the blog posts are shown on the website even if they're set on published: false.

I talked with Ricardo on Discord, and was told to add filter: published: true in the content for the moment for a quick fix, but I wanted to post this bug here because it might be an issue with Grav.

Does sound like a bug. Are you running Grav 1.6?

I'm running Grav 1.7.0-beta.5.
