What's new in 2.1.0
New Features - All-New Official Runtime Compatibility Core: Introduces a unified, strongly-typed virtual modification framework and lifecycle management. It organizes compatibility adaptations—using layers such as modification points, Adapters, and Providers—to standardize modifications to official behavior while supporting debugging and observability for development. - Expanded Official Runtime Adaptation Capabilities: Adds support for the new Codex runtime layout, renamed avatar overlays, structured App Host messages, and more comprehensive official runtime reporting and state synchronization. - Enhanced Launcher Capabilities: Prioritizes the installed PWA when launching OpenCodex; supports backing up and restoring official runtime resources from the previous version, reducing recovery costs after official runtime updates. - Enhanced Smart Scheduling: Supports dynamic scheduling tiers and configurable history limits for categories; the UI displays the currently selected tier and category fallback status, and restores the scheduling summary after runtime updates. Default scheduling configurations have also been updated for the GPT6 release. Optimizations/Refactoring - Optimized initial web loading and session recovery, significantly improving load speeds. - Enabled immutable caching for patched static resources with content hashes, reducing redundant data transfer for large assets during remote access. - Upgraded plugin development capabilities; implemented the Plugin v2 SDK based on the new virtual modification framework (see documentation for details). Fixes - Fixed compatibility issues related to the new official runtime layout, Window Controls Overlay (WCO) lifecycle, macOS runner startup, and ASAR integrity verification. - Fixed issues regarding scheduling summaries following WebSocket/IPC state changes and cross-thread request blocking. - Fixed sorting issues in the "Recently Updated" project list. - Fixed token usage display issues. - Fixed mobile-specific issues: sidebar touch scrolling, drag gesture conflicts, iOS layout restoration, and sidebar interactions after creating new tasks. - Fixed issues with browser window focus events, smart scheduling menu transparency, tooltips disappearing during scrolling, official app menu icon paths, and Gateway logout injection after visiting the settings page. - Fixed issues with hidden tray hooks after Electron updates and race conditions in Guardian approval status. - Fixed other known issues.
Added the “Smart Scheduling” plugin: Auto is now available in the model list and, once selected, automatically chooses a model and reasoning effort for each task. Users can customize scheduling tiers, models, reasoning effort, and classification rules in the Codex/ChatGPT settings, allowing the scheduling strategy to adapt to different users and usage scenarios.
Added real-time synchronization of Codex/ChatGPT Desktop task lists and activity status in the Web interface.
Added the “Project Recent Sort” plugin: the “Recently Updated” mode now sorts projects by their latest activity while preserving project order in “Manual” mode.
Fixes
Added support for the latest Codex/ChatGPT Desktop chunked IPC and sidebar bootstrap protocols, restoring Web refresh and initial data loading.
Fixed App Host relay failures after WebSocket reconnection, as well as task list and activity updates stopping after IPC resets or reconnections.
Fixed failures when copying certain official runtime files from WindowsApps/MSIX installations by adding a chunked read/write fallback.
Fixed account entry detection across different interface languages and the application menu not being hidden in the updated renderer.
Fixed the mobile sidebar not collapsing after creating a new task, with compatibility for updated official icons and sidebar markers.
Fixed Token Usage information not following the visibility of other action buttons, and aligned its font size with the timestamp style. …
