帖子和页面感觉更快，这要归功于惰性加载图片。
Images give your story a lot of impact, but they can sometimes make your site seem slow.
In WordPress 5.5, images wait to load until they’re just about to scroll into view. The technical term is ‘lazy loading.’
On mobile, lazy loading can also keep browsers from loading files meant for other devices. That can save your readers money on data — and help preserve battery life.

WordPress sites work well with search engines.
Now, by default, WordPress 5.5 includes an XML sitemap that helps search engines discover your most important pages from the very minute you go live.
So more people will find your site sooner, giving you more time to engage, retain and convert them to subscribers, customers or whatever fits your definition of success.

插件和主题的自动更新
Now you can set plugins and themes to update automatically — or not! — in the WordPress admin. So you always know your site is running the latest code available.
You can also turn auto-updates on or off for each plugin or theme you have installed — all on the same screens you’ve always used.
通过上传ZIP文件更新
如果手动更新插件和主题是你的事情，现在也更容易-只需上传一个ZIP文件。
New block patterns make it simple and fun to create complex, beautiful layouts, using combinations of text and media that you can mix and match to fit your story.
You will also find block patterns in a wide variety of plugins and themes, with more added all the time. Pick any of them from a single place — just click and go!
Every release adds improvements to the accessible publishing experience, and that remains true for WordPress 5.5.
Now you can copy links in media screens and modal dialogs with a button, instead of trying to highlight a line of text.
You can also move meta boxes with the keyboard, and edit images in WordPress with your assistive device, as it can read you the instructions in the image editor.
