RC からのコメント
From wikitech-l mailing list:


 * 46934
 * There is just one issue that I would like to mention: in my database (MySQL) pre-upgrade jobs have job_random set to 0 and do not seem to be picked up - not even when I use the option --type=replaceText.  I can repeat the replace text operations, so this is not big problem for me.  However, if this is the normal behaviour for an upgrade, maybe it should be  mentioned in the notes somewhere.

メール通知をより明確に
Bug 14901 – Email notification mistakes log action for new page creation, third most reported open MediaWiki bug, has been fixed. Consequently, notifications now state clearly what action was performed on the watched pages in case they are created, deleted, restored, moved or changed.

There are still some known issues. If you customised MediaWiki:Enotif body on your wiki, you have to delete or update it; see also full documentation.

スキン

 * The CologneBlue skin has been refactored to make it relevant again, more compatible with existing scripts, and more similar in structure to Vector and Monobook, reusing a lot of existing code.

The only major difference for end-users should be a slight reordering of the sidebar menu (the "Context" submenu was removed and its contents merged into other ones). If you were, however, depending on the exact HTML it used to produce, you'll need to review your tools.

ContentHandler
As part of the Wikidata initiative, 1.21 adopts an extensible framework so that pages can contain something other than wikitext.

Right now, built-in content types are limited to


 * wikitext - wikitext, as usual
 * javascript - user-provided JavaScript code
 * css - user-provided CSS code
 * text - plain text

Extension developers can create additional content types. Extension:EventLogging uses ContentHandler to implement a namespace for JSON schemas, and may be used as a reference.


 * The new ContentHandler might affect diff rendering, handing of CSS and JavaScript pages, import/export (including PDF export), and API stuff, especially when rendering and editing. Also look out for issues in template rendering, images and media handling, localisation, and mobile device access.  (merged on Oct 9)

高解像度の画像への対応

 * High-resolution image support. This is a work-in-progress that tries to give higher-res images to high-density screens that can support it, like new Retina displays.  More info is at .  Administrators may need to watch out for higher load on their image scaling software.

Ajax を使用した巡回
The features users have waited for longest: One-click AJAX 巡回. With this new feature, users can mark revisions or pages as having been "patrolled" with a single click while staying on the current page. (bug 7851)

国際化

 * The general logging framework was made completely localisable at last, by fixing bug 24156 (deferred since MediaWiki 1.18). The logging for each action (whether in core or extensions) might still need to be updated to use the new system, though.
 * MediaWiki:Contributions now reflects the gender of the user.

新しいアカウント

 * It's now easier to create accounts for other users by sending a temporary password via e-mail: Special:CreateAccount now shows a checkbox for logged-in users to use this feature, rather than a button.
 * Account API: bots and other scripts can now use the API to create user accounts, rather than attempting to pseudo-submit the HTML form.

アカウント作成時の「ようこそ」
The title of the page you see on account creation is now "Welcome, Username". To make this, the MediaWiki:welcomecreation message was split into two messages:


 * MediaWiki:Welcomeuser:


 * MediaWiki:Welcomecreation-msg:

If your wiki has customized the MediaWiki:welcomecreation message and wants to preserve the customization, an admin needs to
 * 1) move it to MediaWiki:welcomecreation-msg (without leaving a redirect),
 * 2) remove the "== Welcome, $1==" heading line from welcomecreation-msg,
 * 3) (preferably) log out and create an account to see if it works.

JavaScript のメッセージでウィキテキストへの対応を強化
Tired of all your MediaWiki i18n messages showing on the JavaScript side as wikitext? Parse them with jqueryMsg, now with wikilinks and int: transclusion support! For more details, see Manual:Messages API.

ナビゲーションメニューでの意味的見出しの使用
The previous scheme of using (varying per skin) &lt;h4>, &lt;h5> and/or &lt;h6> tags (with nothing apart from the main &lt;h1> above them in the hierarchy) was change to consistently using a &lt;h2> above the entire navigation and &lt;h3>s as portlet headings in all skins.

The &lt;h2> is hidden for normal browsers, but accessible for screen-readers or text browsers.

While this change is minor, it might require similarly minor updates in any customized CSS or JS (or in screen scrapers).

Extended collation support
UCA-based category collations for 68 languages based in Latin, Greek and Cyrillic alphabets are now supported. You can use them by setting, where   is the appropriate language code.
