# Changelog

All notable changes to this project will be documented in this file.

## [6.0.0] - 2026-09-06

- feat: migrate to zola v0.23 / Tera v2, the minimum zola version required is now `v0.23.4`, shortcodes are rewritten as Tera components
- feat: tag links are now generated via zola's taxonomy API instead of hardcoded `/tags/` paths, so the `taxonomy_root` config option (e.g. `taxonomy_root = "blog"` for `/blog/tags/xxx` URLs) is respected
- feat: support multiple blog-like list sections — post pages now read config from their own parent section instead of the `blog_section_path` one, and each list section can have its own feed (`generate_feeds = true` in its `_index.md`); `blog_section_path` now only designates the main section used by the home page's recent posts and the tags pages
- refactor: `blog.html` template is renamed to `posts.html`, change `template = "blog.html"` to `template = "posts.html"` in your blog section's `_index.md`
- feat: display options (`toc` / `code_copy` / `comment` / `math` / `mermaid` / `reaction` / `outdated_alert` / `date_format`, etc.) now follow a unified fallback chain: post front-matter → section `_index.md` → `[extra]` of `zola.toml`, the closest one wins — notably `math` / `mermaid` can now be enabled for a whole section, and site-wide defaults can be set in `zola.toml`
- refactor: several options are renamed for clarity: `force_theme` (`false | "light" | "dark"`) → `color_scheme` (`"auto" | "light" | "dark"`), `copy` → `code_copy`, `outdate_alert*` → `outdated_alert*`, and `id` of the home section → `handle`
- refactor: the `sections` config option is renamed to `nav`, and its `is_external` field is removed — a `path` starting with `/` is an internal link, anything else (e.g. an `https://` URL) is treated as an external link automatically; external nav links now show a `ne-resize` cursor
- refactor: `name` / `handle` / `bio` / `avatar` / `links` of the home page are moved from the home section's `_index.md` to `[extra]` of `zola.toml`
- refactor: the example config file is renamed from `config.example.toml` to `zola.toml.example`, following zola v0.23's new default config file name `zola.toml` (the old `config.toml` name still works)
- refactor: the callout components (`note` / `tip` / `important` / `warning` / `caution`) are removed in favor of zola's native [GitHub alert syntax](https://github.com/orgs/community/discussions/16925) (`> [!NOTE]`), styled with icon and title by the theme; the title texts can be customized via css variables (`--callout-note-title`, etc.)
- feat: collections are redesigned — item appearance (`layout = "card" | "row" | "tile" | "gallery"`) and arrangement (`flow = "stack" | "inline" | "grid"`, the grid adapts its column count to the available width) are now declared at the collection level, and all layouts share one unified set of item fields (`title` / `subtitle` / `content` / `icon` / `image` / `link` / `badge` / `tags` / `featured`) with graceful degradation; item `link`s are auto-detected as internal or external, and `image` supports section-colocated files; `card` items can additionally show a picture on the left via `image` (the small `icon` before the title is a separate field)
- chore: upgrade Mermaid to 11.17.2 and KaTeX to 0.18.6, refreshing KaTeX resource integrity hashes

### Migrate from zola v0.22

Zola v0.23 removed shortcodes and Tera macros in favor of [Tera components](https://www.getzola.org/documentation/content/overview/#templating-your-content), and your markdown content is now itself a Tera template. Once you update zola and this theme, you need to update your content accordingly:

- Shortcode calls in your markdown must be rewritten in component syntax. Arguments other than strings are wrapped in `{...}`:
  - `{{ figure(src="...", width="600") }}` → `{{ <figure src="..." width="600" /> }}`
  - `{% quote(cite="...") %} ... {% end %}` → `{% <quote cite="..."> %} ... {% </quote> %}`
  - `{{ youtube(id="...", autoplay=true) }}` → `{{ <youtube id="..." autoplay={true} /> }}`
  - `{{ collection(file="projects.toml") }}` → `{{ <collection file="projects.toml" section /> }}` (note the extra `section`)
- The callout shortcodes are removed, rewrite them with the GitHub alert syntax (custom titles are not supported, the title is always the type name):

  ```md
  {% note(title="Note") %}
  note text
  {% end %}
  ```

  becomes:

  ```md
  > [!NOTE]
  > note text
  ```

- For `figure` with a colocated image, pass the page context: `{{ <figure src="img.png" page /> }}` (or `section` instead of `page` when used in a section's `_index.md`)
- `width` / `height` of `figure` must be strings: `width="600"`, not `width=600`
- Literal `{{` or `{%` in your content (e.g. code blocks showing template syntax, GitHub Actions `${{ ... }}`) must be wrapped with `{% raw %}` ... `{% endraw %}`, otherwise zola will try to interpret them as Tera syntax. For files full of such content, you can instead list them in the `skip_content_templating` config option (glob patterns) to opt them out of templating entirely (components won't work in those files)
- Component calls must be at the top level of your markdown content — nesting them inside a list item is no longer supported (the component's HTML output breaks the list's indentation rules and produces broken HTML). If you had e.g. a callout inside a list item, move it out of the list
- The `date` filter is now backed by [jiff](https://docs.rs/jiff/latest/jiff/fmt/strtime/index.html) instead of chrono. Common `date_format` values like `"%b %-d, %Y"` still work, but chrono-specific specifiers (e.g. `%+`) are no longer supported and will fail the build — check your `date_format` options against the jiff docs
- Syntax highlighting CSS files (`giallo-light.css` / `giallo-dark.css`) are now generated directly into the output directory instead of `static/`, so you can remove them from your `static/` folder and `.gitignore`
- If you have custom templates that override serene's, they must be migrated to Tera v2 as well, see the [Tera migration guide](https://github.com/Keats/tera/blob/master/MIGRATION.md)
- The `blog.html` template is renamed to `posts.html`: change `template = "blog.html"` to `template = "posts.html"` in your blog section's `_index.md`
- Zola's default config file name is now `zola.toml` — you can rename your `config.toml` to `zola.toml` (optional, the old name still works)
- Several options are renamed, update them in your `zola.toml` / section `_index.md` / post front-matter:
  - `force_theme = false | "light" | "dark"` → `color_scheme = "auto" | "light" | "dark"` (`false` becomes `"auto"`)
  - `copy` → `code_copy`
  - `outdate_alert` / `outdate_alert_days` / `outdate_alert_text_before` / `outdate_alert_text_after` → `outdated_alert` / `outdated_alert_days` / `outdated_alert_text_before` / `outdated_alert_text_after`
  - `id` in the home section's `_index.md` → `handle`
  - `sections` in `zola.toml` → `nav`, and remove the `is_external` field from its entries (external links are now detected automatically from the `path`)
  - `name` / `handle` / `bio` / `avatar` / `links` move from the home section's `_index.md` to `[extra]` of `zola.toml`
- Collection toml files use a new schema, update them as follows:
  - each `[[collection]]` becomes `[[item]]`, and the per-item `type` moves to a single collection-level `layout` at the top of the file: `card` → `layout = "card"`, `card_simple` → `layout = "row"` plus `flow = "stack"` (rename its `content` to `subtitle`), `entry` → `layout = "row"`, `box` → `layout = "tile"`, `art` → `layout = "gallery"`, `art_simple` → `layout = "gallery"` plus `flow = "grid"`
  - rename item fields: `img` → `image` (`icon` keeps its name), and both `date` and `footer` → `badge` (a short mark rendered as-is: a year, a date range, a rating, a status...)
  - remove `type = "br"` items — arrangement is now controlled by the collection-level `flow` (`"stack"` / `"inline"` / `"grid"`) option

### Migrate from zola v0.21

Since this version, the minimum zola version required has changed to `v0.22.1`.

Replace the old `[markdown]` section in your `config.toml`:

```toml
# Old (remove these)
[markdown]
highlight_code = true
highlight_theme = "css"
extra_syntaxes_and_themes = ["themes/serene/highlight_themes"]
highlight_themes_css = [
  { theme = "serene-light", filename = "hl-light.css" },
  { theme = "serene-dark", filename = "hl-dark.css" },
]
```

With the new format:

```toml
# New
[markdown]
github_alerts = true  # optional, enables GitHub-style callout syntax

[markdown.highlighting]
style = "class"
light_theme = "github-light"  # or any zola built-in theme
dark_theme = "github-dark"    # or any zola built-in theme
```

You should also delete the generated `hl-light.css` and `hl-dark.css` files from your `static/` directory if you have them.
The new generated css files for code highlighting will be `giallo-light.css` and `giallo-dark.css`. (giallo is zola's new syntax highlighter)
