Major new capabilities
What's New in V3
AI Chat with Multi-Agent System
10+ AI providers (Anthropic, OpenAI, Google, Ollama, LM Studio, Mistral, Azure OpenAI, Vertex AI, AWS Bedrock, GitHub Copilot). Multi-session sidebar, parallel sub-agents with worktree isolation, hybrid memory (vector + keyword), plan-mode approvals, hooks, custom skills, and @-mention file attachments.
Voice-to-Chat Dictation
Speak instead of type. Local Whisper inference (GPU or CPU) or OpenAI Whisper API, global push-to-talk hotkey works even when the app is unfocused, 10 languages plus auto-detect.
OPC UA Client
Full address-space browser with live subscriptions, event monitoring with severity filters, historical trend charts, method calls, and read/write for simple values, structs, and UDTs. Security modes None / Sign / SignAndEncrypt.
Signal Trace & Dashboards
Oscilloscope-style live charts with multi-signal support, edge triggers with pre/post-trigger buffers, crosshair measurement, and per-signal Y-scale and display formats. Embed the same plots into interactive dashboards.
Tabbed Code Editor
Multiple blocks and files open simultaneously with split view. Inline AI chat (Ctrl+I) with accept/reject diff preview, 60+ language syntax highlighting, SCL snippets, minimap, and automatic dark/light theme sync.
Full Git Client
Visual commit history with branch graph, interactive rebase with drag-and-drop, GitFlow, hunk-level staging, bisect, blame, file history, GPG signing, LFS with image diff, submodules, worktrees, and configurable external diff/merge tools.
SCL Unit Testing
AI writes your test suites — inline chat (Ctrl+I) in the suite editor, AI-badge on generated tests. Run on PLCSIM Advanced with live progress, variable timeline charts, click-to-navigate from failures into the editor, hardened F-CPU safety guard.
Password Vault
AES-256-GCM encrypted vault with PBKDF2 key derivation for TIA Portal know-how protection passwords. Bulk protect/unprotect with crash-recovery journal, hierarchical folder/block password resolution, full EN/DE/FR/IT localization.
