我去，IDEA 竟然免费了？！

Core Viewpoint - JetBrains has announced a unified distribution for IntelliJ IDEA, allowing users to access more features in the free version while maintaining a subscription model for advanced functionalities [1][3]. Group 1 - The new setup will replace the separate Community and Ultimate versions with a single installation program, where Ultimate features still require a subscription to unlock [1][3]. - Starting from version 2025.3, free users will gain access to many features previously exclusive to the Ultimate version, such as code highlighting for popular frameworks like Spring and Quarkus, and project creation wizards [3][4]. - The free version will now allow users to view database designs directly within IDEA, although data access and SQL execution will not be available [4]. Group 2 - Previously, if a subscription expired, users could not open projects in the Ultimate version, but now they will automatically revert to the free version, allowing project access and editing [4]. - JetBrains' strategy appears to balance the needs of free users while ensuring the sustainability of its business model, potentially attracting more developers to its ecosystem and converting them into paying customers [4][5]. - JetBrains has shown commitment to providing free versions of its products, including WebStorm, while also maintaining open-source versions [5].
