# Unreleased changes Changes merged into `development` that have not yet been released to `main`. --- ## `mdcms build` patches `` with sitename `mdcms build` now rewrites the `<title>` tag in `index.html` with the value of `sitename` from `config.yml`. Previously the tag was hardcoded (`MD-CMS`) in older templates, or blank in the starter template, so link previews in WhatsApp, Slack, and other crawlers that read static HTML showed the wrong name. --- ## Untranslated posts now visible in all categories **Status:** On `development`, pending release. ### What was broken When the category system is enabled, a post file without a category suffix (e.g. `posts/my-post.md`) was silently assigned to the default category only. Switching to any other category caused those posts to disappear from the nav and from `posts-*` tag listings — even though no translated version existed. If you wrote posts without a language suffix, they simply vanished the moment a visitor switched category. Pages without a category suffix are unaffected: they continue to be assigned to the default category, which is the correct behaviour for pages. ### What it does now Posts without a category suffix are treated as uncategorised — meaning they appear in every category. A post called `my-post.md` now shows up regardless of which category is active. A post called `my-post.en.md` still appears only in the `en` category as before. Mixed situations work as expected: if you have both `my-post.md` and `my-post.nb.md`, the Norwegian variant is shown when the `nb` category is active, and the bare `my-post.md` is shown for every other category. ### What changes in the build output After rebuilding a site with `mdcms build`, affected post entries in `nav.yml` gain an `uncategorized: true` field: ```yaml - file: posts/my-post.md title: My Post sort: 100 uncategorized: true ``` In `search.json`, these entries carry `"category": null` instead of the default category code. This is what tells the renderer to include them universally. A rebuild is required for existing sites to pick up the change. --- ## Fix: `config.yml` YAML parse errors now abort the build with a clear message A malformed `config.yml` (e.g. a stray tab character, which YAML forbids as a token starter) previously caused `read_config` to silently return an empty dict. The build would proceed with no config — categories disabled, no default category code — producing a broken `nav.yml` with wrong filenames and missing `variants` fields, so category-variant pages would not appear in the sidebar. `read_config` now raises `ClickException` on both `OSError` and `yaml.YAMLError`, aborting the build with a descriptive error message instead of continuing silently with an empty config.
