WordPress 4.7 Beta 2 发布

WordPress 4.7 Beta 2 发布了，自 WordPress 4.7 Beta 1 以来值得关注的更新：

Twenty Seventeen: The theme wasn’t being installed on upgrades – sorry about that! Now you should see it if you’re upgrading an existing site. There are also plenty of fixes, especially for the header and small screen views.
Edit shortcuts: These are always visible while editing (hide them on bigger screens by collapsing the controls) and should now work properly in Firefox. (#27403and #38532)
REST API endpoints: There have been a number of changes over the past week; your attention is requested on the following:
- The DELETE response format has changed and may need to be accounted for. (#38494)
- Enabled querying by multiple post statuses. (#38420)
- Return an error when JSON decoding fails. (#38547)
More developer notes
Various bug fixes: We’ve made almost 150 changes in the last week.
