In this article, I’ll provide an overview of what’s new in this latest release and what you’ll need to keep in mind when you update your WordPress site.
在本文中，我将概述此最新版本中的新增功能以及更新WordPress网站时需要记住的内容。
Don’t forget to perform a full website backup (database and files) before upgrading WordPress 4.5. You might choose to run this directly from your hosting (e.g cPanel or Plesk backup), but there are also some popular backup plugins such as Updraft Plus, BackupBuddy and Backup to Dropbox.
升级WordPress 4.5之前，请不要忘记执行完整的网站备份(数据库和文件)。 您可能选择直接从您的托管服务器运行此程序(例如cPanel或Plesk备份)，但是也有一些流行的备份插件，例如Updraft Plus ， BackupBuddy和Backup to Dropbox 。

When upgrading your site, you may find issues (typically with third party plugins and themes). If this does occur, you can then roll your site back to the latest backup. It’s also worth checking if the theme or plugin providers have published anything about WordPress 4.5 support.
升级网站时，您可能会发现问题(通常是第三方插件和主题)。 如果发生这种情况，则可以将站点回滚到最新备份。 还值得检查主题或插件提供商是否发布了有关WordPress 4.5支持的任何内容。
Where possible, it’s best to apply updates to a test or staging environment so that you can test the changes before applying them to your live site. If that’s not possible, try to choose a time that will be least disruptive to your visitors.
在可能的情况下，最好将更新应用于测试或临时环境，以便您可以在将更改应用到实际站点之前对其进行测试。 如果那不可能，请尝试选择对您的访客影响最小的时间。
If you experience any issues with the upgrade and need help, try basic troubleshooting steps such as disabling your plugins and selecting a default theme to isolate where the problem is. Charles Costa has shared some tips around common WordPress issues and how to fix them. Don’t forget you can also visit the official WordPress support forum, just make sure you read the welcome post.
