Sometimes, it is hard to see important changes in a wikitext diff. This screenshot of a wikitext diff (click to enlarge) shows that the paragraphs have been rearranged, but it does not highlight the removal of a word or the addition of a new sentence.
If you enable the Beta Feature for "ビジュアルディファレンス", you will have a new option. It will give you a new box at the top of every diff page. This box will let you choose either diff system on any edit.
Click the toggle button to switch between visual and wikitext diffs.
In the visual diff, additions, removals, new links, and formatting changes will be highlighted. Other changes, such as changing the size of an image, are described in notes on the side.
This screenshot shows the same edit as the wikitext diff. The visual diff highlights the removal of one word and the addition of a new sentence.
You can read and help translate the user guide, which has more information about how to use the visual editor.
The 2017 wikitext editor is available as a Beta Feature on desktop devices. It has the same toolbar as the visual editor and can use the citoid service and other modern tools. The team have been comparing the performance of different editing environments. They have studied how long it takes to open the page and start typing. The study uses data for more than one million edits during December and January. Some changes have been made to improve the speed of the 2017 wikitext editor and the visual editor. Recently, the 2017 wikitext editor opened fastest for most edits, and the 2010 WikiEditor was fastest for some edits. More information will be posted at mw:Contributors/Projects/Editing performance.
The visual diff tool was developed for the visual editor. It is now available to all users of the visual editor and the 2017 wikitext editor. When you review your changes, you can toggle between wikitext and visual diffs. You can also enable the new Beta Feature for "Visual diffs". The Beta Feature lets you use the visual diff tool to view other people's edits on page histories and Special:RecentChanges.

I explain your message and "Discover Russia. Alumni and Professors" in Japanese. 日本語で上記メッセージと執筆コンテストについて説明します。「Discover Russia. Alumni and Professors」はWikimedia Russiaが主催する執筆コンテストで、2018年4月9日から23日までコンテストのバナーを表示する予定だそうです。コンテストの対象となるのはロシアの大学もしくはその他の教育機関の教授や講師、卒業生の記事です。ノミネートされるのは基本的には国連の公用語の6言語で立項された記事ですが、「日本におけるロシア年」（外務省ホームページ参照）で日露交流強化期間であることから日本語版の記事も特別賞のみ対象となっています。 Association of Honorary Citizens, Mentors and Talented Youthがコンテストの賞金を出費することになっており、日本語版で10記事以上を立項した上位2名には特別賞で賞金として1万ルーブルが出るそうです。--SilverSpeech（会話） 2018年3月28日 (水) 01:06 (UTC)
