Version 1.0.6

March 26, 2026

Chat deduplication stability and conversational notebook execution hardening

MLJAR Studio 1.0.6 is a stabilization release focused on chat reliability in the Electron app, with stronger websocket/message deduplication and safer conversational notebook execution behavior.

  • Improved websocket/message deduplication to prevent duplicated user prompts and streamed assistant responses
  • Improved Electron chat reliability where sidebar messages could previously appear multiple times
  • Tightened conversational notebook execution plumbing to reduce malformed auto-fix loops from parser/sanitization edge cases
  • Reduced chat-flow instability and made day-to-day behavior more predictable and production-safe

Version 1.0.5

March 25, 2026

Provider-aware AI access fixes, chat stability hardening, and AutoLab example update

MLJAR Studio 1.0.5 focuses on AI access correctness and runtime stability. This release fixes provider-aware entitlement handling for Ollama/OpenAI paths, removes legacy launcher fallbacks, hardens chat send and frontend initialization behavior, and updates the AutoLab House Prices example dataset URL.

  • Fixed provider-aware AI access gating for non-MLJAR providers to avoid incorrect "AI subscription required" behavior
  • Fixed launcher command routing by removing legacy fallback commands that could trigger wrong entitlement paths
  • Improved chat send stability with duplicate-send protection at input and transport levels
  • Added frontend core singleton guard to prevent duplicate initialization and repeated websocket clients/prompts
  • Updated AutoLab House Prices example dataset URL to `data_train.csv`
  • Improved Studio AI guard messaging and local-provider entitlement logic (`ai_local_provider_access`)

Version 1.0.4

March 24, 2026

Structured AutoML reports and NumPy 2 compatibility

MLJAR Studio 1.0.4 upgrades AI Data Scientist reporting with structured, LLM-friendly AutoML output and updates dependency compatibility so mljar-supervised works with modern NumPy versions.

  • Added structured AutoML reports optimized for LLM-friendly output
  • Improved AI Data Scientist report format for more consistent machine-readable sections
  • Removed the `numpy==1.26.4` dependency pin; mljar-supervised now works with NumPy > 2.0

Version 1.0.3

March 23, 2026

Stronger runtime stability, AutoLab data setup, and smarter run summaries

MLJAR Studio 1.0.3 focuses on reliability and flow quality across conversational notebooks and AutoLab experiments. This release adds stronger timeout/cleanup guards, improves experiment data and results-directory UX, introduces LLM-based run summaries, and fixes multiple state, session, and startup edge cases.

  • Added Ollama Cloud support for remote model connectivity
  • Added watchdog and timeout guards to prevent hanging "Thinking" and "Checking packages" states
  • Improved AutoLab Step 2 data setup with desktop-friendly multi-file selection and persisted `data_files`
  • Upgraded run summary generation to LLM-based synthesis and standardized report delivery via `run_summary`
  • Fixed notebook rename conflicts and prevented cross-notebook variable leakage in conversational workflows
