Added

• Run in Separate Process option for optimization, enabled by default. Runs optimization in a process separate from Rhino, avoiding conflicts with Grasshopper's Python.
• Convert Result to Tunny Log component. Writes variables and objective function values to the Tunny log format, so results from other plugins can be analyzed with Tunny's tools.
• Support for Hidden and Faint wire displays in the Tunny Fishing component.
• Support for LAN Zoo licensing.
• Enhanced samplers from the Optuna update:
  • GP acquisition functions now allow PI, UCB, and Thompson Sampling in addition to EI.
  • CMA-ES sampler split into Restart CMA-ES and CMA-ES with Refinement.
• Tunny Dashboard, a new results analysis feature, is now available.

Changed

• NSGA-III's dividing parameter default is now calculated automatically. The previous fixed default often produced too few divisions.
• Rhino command TunnyRunDashboard renamed to TunnyRunOptunaDashboard, to distinguish it from the new Tunny Dashboard.
• Visualize tab's "Browser" ribbon group renamed to "Dashboard".
• Improved UI responsiveness during optimization by making progress updates asynchronous.
• Fixed the version check process so it no longer hangs indefinitely on a slow or unresponsive network.
• The Python 3 component warning now suggests enabling Run in Separate Process to avoid conflicts, and no longer appears if the option is already enabled.

Fixed

• Improved Python environment reinstallation behavior on Windows, including notifying the user when a Rhino restart is required.
• Tunny now shuts down safely if Python environment initialization fails, and recommends reinstalling from the application menu.
• Rhino restart is now requested instead of leaving Tunny in a partially initialized state, addressing Python's restriction against restarting its interpreter within the same Rhino session.
• Installing Python packages after Python has already been used in the same Rhino session no longer corrupts the environment; installation is deferred to the next startup instead.
• An interrupted or failed installation is no longer treated as complete, and is retried automatically at the next startup.
• Failures during Python package installation are now correctly detected and reported, instead of being misreported as success.
• Reinstallation is now scheduled automatically for the next startup if the Python runtime cannot be initialized.
• Errors during plot (graph) generation no longer crash Rhino; an error message is shown instead.
• Errors from the worker process used by Run in Separate Process are now logged correctly instead of being overwritten by secondary errors.
• Corrupted configuration files are now backed up before being deleted, with a notification to the user, instead of being silently removed.
• Fixed CMA-ES and Restart CMA-ES no longer working due to an upstream Optuna API change.
• Fixed CMA-ES / Restart CMA-ES using a hardcoded default Population Size instead of Optuna's automatic calculation.
• Fixed garbled Japanese characters in the Live Chart.
• Fixed a Rhino crash when restoring a non-existent Trial ID to Grasshopper.
• Fixed a crash on first startup on Rhino 7 (.NET 4.8) when agreeing to the Terms of Use.
