Aug 1, 2025In August 2025, delivered three key changes across eclipse-theia/theia that strengthened UI reliability, security, and UX for plugin developers and end users. Fixed plugin menu icon rendering and tooltip display, hardened status bar tooltips with SafeCommand for RPC boundaries, and corrected webview link forwarding under Shadow DOM to ensure correct behavior in complex webviews (e.g., GitLens). These changes reduce visual inconsistencies, mitigate security risks in command links, and improve navigation across embedded content.

Mar 1, 2025March 2025 — Eclipse Theia/Theia monthly summary. Delivered enhancements to AI-assisted workflows and improved robustness of LLM integration in the eclipse-theia/theia repo. Key features include enhanced LLM chat and prompt editing UX with autocompletion improvements, variable completion for prompt templates, and thinking support via a centralized LanguageModelService with per-provider/model/agent request settings. Also implemented explicit ToolRequest parameter handling to enforce mandatory parameters (defaulting to an empty object when missing) to improve LLM output quality across packages. Major bug fix includes preventing autocompletion from triggering inside words, increasing input accuracy and UX reliability. These changes are traceable to commits 14908a29b2d997c678d452874701fd537c20cced, 05abadcd9a783cc86c95ff947fc27d62359e171f, 4877a0b03e4940c27206ed17c7221b7855e74d7e, and e266b01d82b55a56f2ab327117fc19523f2022e5.
