Changelog

All notable changes to the DVGE engine are documented here. Versioning strictly follows the Semantic Versioning standard.

[5.8.0] — 2026-04-30 ✦ Current Release

Master Stabilization and Legal Compliance (The Master Sync)

Deterministic Boot (Honest Boot Sequence): Definitive elimination of the black screen via an honest initialization sequence. The UI now reports real-time hardware scanning (GPU/CPU), esbuild pipeline synchronization, and module mounting.
External Link Optimization: Implemented a global Electron handler to force all external links to open in the system’s default browser, significantly improving security and UX.
UI/UX Refinement:
- Aesthetic unification of contact links (GitHub, Portfolio, Gmail).
- Elimination of redundancy in modals (removed duplicate close buttons).
- Integration of a direct Gmail compose deep link.
Roadmap v6 Synchronization: Laid the groundwork for modular architecture and batch rendering capabilities.

[5.7.0] — 2026-04-28

Technical Transparency & Pro Loader (The Visibility Update)

esbuild Pipeline Visualization: Integration of real-time compilation logs inside the UI. Developers can now see exactly when a plugin is transpiling, eliminating uncertainty during complex logic changes.
Dynamic Initialization Loader: Implementation of a sequential loading system that replaces the initial black screen with an informative progress bar detailing the state of internal modules.

[5.6.0] — 2026-04-26

Project Management & Autonomy (The Freedom Update)

Dependency Auto-Fetch (Chromium & FFmpeg): The engine now automatically detects and downloads its own rendering binaries into %APPDATA%\DVGE\bin, eliminating the need for a globally installed Chrome browser.
Comprehensive Project Management: New Gallery interface allowing users to securely rename and delete projects via atomic IPC calls.
Plugin Integrity Checks: The system now detects missing or corrupted plugins before opening the editor, displaying error badges and locking access to prevent unexpected crashes.
Frame 0 Stabilization: Critical fix in RenderWrapper ensuring properties are fully injected before the first frame is captured, eliminating transparent flickering.
Solo Developer Identity: Updated narrative on the landing page and documentation to reflect its independent nature and commitment to future certification.

[5.5.0] — 2026-04-23

GA Artifact Edition (Knowledge Bridge)

Native Knowledge Bridge: The engine caches a DVGE-Master-Rules.pdf file and exposes it as a drag zone inside the “DVGE Studio Master” plugin inspector. By dragging directly into an AI chat (Claude, Gemini, ChatGPT), the assistant receives the complete engine context — Sandbox rules, ctx API, Shadow DOM constraints, and the utility table — without needing to copy raw text.
Internal PDF Auto-Generator: A silent Electron window compiles engine rules to a temporary cached PDF file (%TEMP%/DVGE-Master-Rules.pdf), bypassing AI plain text length restrictions.
Studio Master Refactor: The “DVGE Studio Master” plugin now incorporates standardized support for the prompt schema field while maintaining high UI fidelity.

[5.4.0] — 2026-04-23

Production Stabilization and Alpha Channel (The Alpha Fix)

Transparency Transformer: Implementation of critical Chromium flags (--transparent-background-color=0) and evaluatePage injection to guarantee true transparency in ProRes 4444.
Data Probe System: New data injection system via an internal HTTP endpoint (/props.json) to prevent complex data truncation caused by Windows CLI limits.
Engine Compatibility: getElementById polyfill inside the plugin root container to support legacy and complex logic structures.
Chrome System Bypass: Forced usage of the system’s Chrome executable for enhanced reliability in Windows environments.
DaVinci Optimization: Adjusted pixel format to yuva444p10le with verified transparency metadata.

[5.3.0] — 2026-04-23

Infrastructure Audit and Stabilization (Kernel Hardening)

Definitive “Black Background” Resolution: Diagnosed and fixed the transparency issue in ProRes 4444, restoring the professional alpha channel for broadcast.
System Chrome Bypass: Migrated from Remotion’s chrome-headless-shell to the official Google Chrome binary, resolving silent capture failures.
Kernel Logging (Black Box): Physical logging system (render_debug.log) capturing internal server requests, 404 errors, and real-time console logs.
Rasterization Hardening: Forced CPU flags (--force-cpu-rasterization) to guarantee frame capture even during GPU driver failures on Windows.

[5.2.0] — 2026-04-23

”Iron Wall” Isolation (Bug Purge)

Manual Isolation Server: Independent HTTP server (serve()) for headless rendering, eliminating conflict with the Vite port 3000 that caused the “Black Background” bug.
Strict Naming Convention: Migrated composition IDs to kebab-case to comply with Remotion 4.x strict validations.
Deterministic Synchronous Engine: Refactored RenderWrapper to guarantee atomic DOM injection before frame capture.
Native Transparency: Restored true alpha channel for ProRes 4444 exports.

[5.1.0] — 2026-04-23 (GA)

Next-Generation Rendering Engine (Zero-Bundle Runtime)

Zero-Bundle Architecture: Eliminated @remotion/bundler from the runtime. The Remotion entry point is pre-compiled at build time, shrinking the installer from 12,466 files to a single app.asar.
Fast Installation: Installation time plummeted from minutes to seconds.
Explicit binariesDirectory: Native binaries (remotion.exe, ffmpeg.exe) are now safely resolved from app.asar.unpacked, eliminating ENOENT errors in production.
Safe CWD: The rendering process redirects its working directory to %TEMP%, avoiding EPERM permission errors.
Total Compatibility: Rendering via npm run dev and in production is mathematically identical. No plugin API changes.

[5.0.0] — 2026-04-22 (GA)

Smart Engine & Auto-Rescue

Intelligence Layer (Auto-Rescue): The engine detects and automatically wraps scripts that fail to follow the official registration standard (detecting global functions like update or renderDVGE).
Resilient Sandbox: Smart fakeWindow that silently intercepts and nullifies requestAnimationFrame, protecting the integrity of ProRes 4444 rendering.
API Simplification: Introduced ctx.utils.loop(frame, duration) for perfect cyclic animations.
AI-Native Workflow: Significantly higher “One-Shot” success rate when running AI-generated code.

[4.1.0] — 2026-04-21 (GA)

Plugin Catalog & Ecosystem

Integrated Catalog: New panel to discover and download plugins directly from the official GitHub repository.
Dynamic Management: Install, update, and delete plugins directly from the UI.
Professional Identity: Social links (GitHub, Portfolio) and direct Gmail contact in the “About” modal.

[4.0.0] — 2026-04-21 (GA)

QA Remediation & GA Architecture

Isolated Sandbox: Plugins run within a fakeWindow without access to Electron APIs.
Secure I/O: Asynchronous and atomic auto-save (.tmp), preventing project corruption.
Graceful Degradation: Crash isolation for plugin code without freezing the main application.
Reactive Error Boundary: Protected interface against malformed manifest.json files.
Deterministic API: Deprecated GSAP in favor of ctx.timeline. Added ctx.state, ctx.refs, utils.spring, utils.typewriter, utils.tickerOffset.

[3.3.0] — 2026-04-21

Editor Edition (Professional HTML-to-Video)

Code Fields: Multiline HTML/CSS editing directly in the sidebar with code type schema fields.
HTML Master Renderer Plugin: High-performance template for rendering pure HTML/CSS compositions.
Manual Save: Button in the sidebar to force a disk write for the project.

[3.2.1] — 2026-04-21

Critical Fix — Universal Plugin Engine

Bug Resolved: The engine previously always rendered the shape of the very first plugin loaded when switching projects; form fields also failed to update.

Dynamic Plugin Engine

Generative Form: The sidebar reads the active plugin’s manifest.json and dynamically generates the correct inputs (string, color, number, image).
Plugin Badge: The sidebar displays the name and version of the active plugin.
Hard Reset on Project Switch: The player is completely destroyed and recreated when switching projects to avoid CSS contamination.

[3.1.0] — 2026-04-21

Core & Developer Experience (DX)

Native Utilities Library (dvEngine.utils): Math functions (lerp, clamp) and easing functions (easeOutCubic, easeOutBounce, etc.) automatically injected into the context.
Silent Auto-Save: Automatic persistence based on 500ms debouncing.
Persistence Indicator: UI in the sidebar showing the save state in real-time.

[3.0.0] — 2026-04-21

Workspace Architecture

Project Manager Backend: Support for persistent projects in Documents/DVG_Projects/<id>.
V3 Lifecycle Injection: Mandatory migration to { awake, start, update } hooks for maximum 60fps performance.
Native Reactive Binding: UI variables now directly impact the update() cycle immediately.

[2.3.0] — 2026-04-21

Hot-Swap Architecture

Stable Bridge Pattern: Centralized event management outside the plugin script to prevent memory leaks.
Leak Detection: Automatic cleanup of Shadow DOM and callbacks before every reload.
