## Description

**Oshirase Ichiran** (おしらせ一覧) displays a list of recent posts or pages anywhere
on your WordPress site using a single shortcode.

お知らせを一覧でシンプルに並べるプラグインです。`[shirase]` をページや投稿に貼り
付けるだけで新着情報を自動表示します。

This plugin is an homage to the original “What’s New Generator” by Hideki Tanaka,
rewritten for modern WordPress with security updates and new features.

#### Features

 * Display a news list anywhere with the `[shirase]` shortcode
 * Show a NEW! badge for recent posts (customizable time period)
 * Optionally mark the latest post with a NEW! badge automatically
 * Choose content type: Posts, Pages, or both
 * Sort by published date or last modified date
 * Filter by category slug (Posts only)
 * Optional “Prev / Next” pagination (on/off toggle)
 * Compatible shortcode `[showwhatsnew]` for migration from What’s New Generator
 * Live preview in the admin settings page

シンプルおしらせは、ショートコードひとつでサイトのどこにでもおしらせ一覧を表示できる
プラグインです。

#### 特徴

 * `[shirase]` を貼り付けるだけでおしらせ一覧を表示
 * NEW! マークの期間指定・最新記事への自動付与
 * 表示コンテンツを「投稿」「固定ページ」「投稿＋固定ページ」から選択
 * 表示順序：公開日順 / 更新日順
 * カテゴリのスラッグ指定で絞り込み（投稿のみ）
 * 「前へ / 次へ」ページネーション（ON/OFF）
 * What’s New Generator からの移行用互換ショートコード `[showwhatsnew]`
 * 管理画面でリアルタイムプレビュー

#### What’s New Generator との互換性

本プラグインは What’s New Generator とは独立したプラグインです。設定は引き継がれ
ません。

    ```
    [showwhatsnew] 互換モードを使う場合は、**必ず What's New Generator を先に無効化**してください。同時に有効にするとショートコードが衝突します。
    ```

## Installation

 1. Upload the `simple-oshirase` folder to `/wp-content/plugins/`
 2. Activate the plugin from the WordPress admin “Plugins” menu
 3. Go to “Settings”  “シンプルおしらせ 設定” to configure
 4. Add `[shirase]` to any page or post where you want to display the notice list

## FAQ

### Can I migrate settings from What’s New Generator?

No. Simple Oshirase uses its own option key (`simple_oshirase_options`). Please 
reconfigure after activation.

### Can I keep using `[showwhatsnew]`?

Yes. In the settings page, switch the shortcode to `[showwhatsnew]` (legacy mode).
Make sure to deactivate What’s New Generator first to avoid conflicts.

### Does it work in widgets?

Yes. Paste `[shirase]` into a Text widget and it will display correctly.

### What languages is the admin UI in?

The admin settings page is currently in Japanese only. English localization is planned
for a future release.
