AI-Powered Development
With the new AI code completion model powered by JetBrains’ proprietary Mellum LLM, developers can experience faster and smarter code suggestions. Inline AI prompts and syntax-highlighted code suggestions make coding smoother, while the ability to incrementally accept multiline suggestions enhances control.
“Unlike typical large language models, Mellum is built specifically for coding. We are focused on creating a smaller, optimized model that significantly reduces latency, offering developers suggestions almost instantly. This makes Mellum more efficient than many of the third-party models currently available on the market,” JetBrain said in their blog introducing Mellum.
Enhanced Debugging and Testing
The release introduces xdebug_notify() support for structured debugging outputs and full integration with Pest 3.0. New features include mutation and parallel testing for Laravel developers, streamlining test workflows directly in the IDE.
Streamlined Version Control and UI Updates
PhpStorm now supports automatic resolution of import statement merge conflicts and introduces a branch name display on the Welcome screen for better project organization. UI enhancements include text highlighting and improved framework component navigation for Vue, Svelte, and Astro.
