Changes in version 1.2.0                        

New features

  - New favicon_png (and favicon_png_sizes) fields for social_meta(),
    write_manifest(), and init_meta(). Add a PNG fallback alongside an
    SVG favicon: Chromium-based browsers (Chrome, Edge, Comet, etc.)
    don't render SVG favicons in the address bar and fall back to a
    generic globe icon without one, even though the browser tab shows
    the SVG correctly. favicon_png_sizes defaults to "32x32".

  - Added openai_image_generator(), a ready-made generator for
    generate_assets() that calls OpenAI's image API (gpt-image-1 by
    default) and returns the generated image bytes. It is shinyseo's
    only built-in generator: OpenAI's image API is a clean fit for this
    job (one endpoint, one request shape, raster bytes back), and the
    httr package it needs is an optional Suggests dependency loaded only
    when the constructor is called.
    
    Other LLM vendors are welcome as community-contributed generators --
    see the new "Contributing a generator" section in LLM.md for the
    shape a contribution should take. Notably, Claude/Anthropic has no
    image-generation API (it can see images but not generate them), so
    no "Claude generator" is shipped or planned as a parallel to the
    OpenAI one.

                        Changes in version 1.1.0                        

New feature

  - Added generate_assets(), which fills in a missing favicon,
    apple_touch_icon, or image by calling a caller-supplied generator
    function. shinyseo does not integrate with any particular LLM or
    image-generation service itself -- generator is the caller's own
    function, written against whatever API they already have access to
    (OpenAI, Adobe Firefly, a local model, and so on). This keeps the
    package free of any vendor dependency, API key, or running cost of
    its own.

                        Changes in version 1.0.2                        

Bug fix

  - read_meta() (used internally by social_meta(), write_manifest(), and
    init_meta()) now decodes the YAML file as raw UTF-8 bytes instead of
    going through yaml::read_yaml()'s readLines()-based reader. Under a
    non-UTF-8 locale (LC_CTYPE=C, common on minimal servers/CI runners),
    the old reader silently stopped at the first non-ASCII character
    (e.g. Norwegian "æøå"), dropping every field after it with no
    warning or error.

                        Changes in version 1.0.1                        

Improvements

  - init_meta() now reads an existing meta file (if any) and shows its
    current values as defaults for each prompt, so pressing Enter keeps
    what's already there instead of clearing it.

                        Changes in version 1.0.0                        

First stable release. The API (social_meta(), update_meta(),
write_manifest(), init_meta(), and the meta field names) is now
considered stable.

                        Changes in version 0.2.0                        

New features

  - init_meta(path) — interactively answer a few questions at the
    console and write the result to a meta.yml file, so new users can
    get started without reading the field reference first.

  - update_meta(session, title, description, url, image) — update
    metadata reactively from the server without a page reload. Useful
    for multi-tab and multi-route apps. social_meta() now injects the
    JavaScript handler automatically; no extra setup required.

  - write_manifest(meta, path, display, start_url, background_color) —
    generate a www/manifest.json web app manifest from the same metadata
    object used by social_meta(). Call once in global.R.

  - Favicon and PWA fields in social_meta():
    
      - favicon + favicon_type → <link rel="icon"> with automatic MIME
        type detection from file extension
      - apple_touch_icon → <link rel="apple-touch-icon">
      - manifest → <link rel="manifest">
      - theme_color → <meta name="theme-color">
      - short_name → used by write_manifest() for the manifest
        short_name
      - apple_mobile_web_app_capable → <meta
        name="apple-mobile-web-app-capable"> and <meta
        name="mobile-web-app-capable">, so the app runs standalone when
        added to a phone's home screen
      - apple_mobile_web_app_title → <meta
        name="apple-mobile-web-app-title">
      - apple_mobile_web_app_status_bar_style → <meta
        name="apple-mobile-web-app-status-bar-style">

  - Custom meta tags via the custom field — a list of lists where each
    inner list's keys map directly to HTML attributes on a <meta> tag.
    Supports both name= and property= style tags.
