IntelliJ IDEA 2026.1 EAP 3 Brings File Deletion to Recycle Bin and 70+ New Features

JetBrains released IntelliJ IDEA 2026.1 EAP 3, a major update that finally addresses a long‑standing request: when a file is deleted in the IDE it is now moved to the system recycle bin instead of being permanently removed.

Historically, the IDE deleted files directly from the Project view, bypassing the recycle bin and leaving recovery to Local History or Git, which many developers found insufficient, especially for untracked files such as new scripts, SQL files, temporary code, or configuration files.

The new behavior aligns IntelliJ with tools like VS Code, Visual Studio, Finder, and Explorer, providing a familiar, visual, cross‑application, and intuitive way to recover accidentally deleted files without relying on version control.

Beyond the recycle‑bin change, the update includes a long list of enhancements:

1. Spring‑related improvements

Bean injection inlay display

Runtime bean hints in the debugger

Improved API versioning configuration

Automatic SQL dialect detection

2. Java updates

More javac parameter completions

Pattern‑matching diagnostic fixes

3. Kotlin updates

Support for new destructuring syntax navigation

4. Editor experience

MCP Server fixes related to LLM workflows

6. Platform architecture

Removal of ProjectExtension Frontend‑ification of the AI assistant plugin

LSP null‑safety fixes

Support for background write actions

7. Performance and stability

Gradle sync file leak fixes

VFS recursive loading issues resolved

Debugger CPU conflict fixes

Branch‑switch freeze mitigation

Git integration stability improvements

70+ additional known issue fixes

All these changes are positioned to support the future vision of “remote IDE + AI IDE + distributed IDE”.
