IntelliJ IDEA 2023.1 Is Out!

这个牛逼的开发工具，又开始整活了。谨慎升级，有部分插件还没适配！

IntelliJ IDEA 2023.1 is now available, and it comes with a host of improvements and valuable new features!

You can download the new version from our website, update directly from the IDE or via the free Toolbox App, or use snaps for Ubuntu.

IntelliJ IDEA 2023.1 includes refinements for the new UI, which has been overhauled based on the valuable feedback we’ve received from users. We’ve also implemented performance enhancements resulting in faster Maven import and IDE features becoming available earlier when opening projects. The new version provides a streamlined commit process thanks to background commit checks. IntelliJ IDEA Ultimate now supports navigation for Spring Security matchers and request mappings. 

This blog post highlights these significant updates and other notable improvements that have been implemented in IntelliJ IDEA 2023.1.
