Metis 0.2.1

Metis 0.2.1 is a Windows maintenance release that fixes dataset importing and dataset deletion. macOS remains on 0.0.2; the full 0.0.2 feature history is below.

v0.2.1

v0.2.1 latest June 2026

Metis 0.2.1 is a Windows-only maintenance release focused on dataset importing and dataset deletion. The latest macOS release remains 0.0.2.

Fixes

  • Fixed dataset importing: imports now target the active workspace and no longer wrongly report that the workspace dataset limit was reached.
  • Fixed dataset deletion: a single selected dataset can now be deleted directly in the Dataset Manager, not only through the right-click menu or multi-select.
  • Fixed a model canvas that could show a linked dataset with an empty indicator list.

v0.0.2

v0.0.2 June 2026

Metis 0.0.2 makes the app easier to install, smoother to use, and better prepared for complex research models. It also adds macOS downloads.

Downloads

  • Separate Windows and macOS downloads.
  • Bundle and Lite editions available for both platforms.
  • macOS builds available for Apple Silicon (ARM64) and Intel (x64).
  • Version 0.0.2 is the current public release.
  • Version 0.0.1 Windows installers remain available as previous releases.

Better Support for Complex Models

  • You can now build higher-order constructs (HOCs), which are useful when one larger idea is made from smaller related ideas.
  • metis keeps HOC links separate from the arrows used for the main model relationships.
  • When a connection could mean more than one thing, metis asks you to choose the relationship type.
  • Related lower-order constructs can be highlighted from the properties panel, making larger models easier to follow.
  • Results and Tark reports now include the extra tables needed for higher-order constructs.

Look and Feel

  • Choose an accent color for the app and for exported path diagrams.
  • Default accent colors now adapt better to the selected theme.
  • Theme, appearance, and text-size settings are easier to adjust.
  • Storage-location settings are clearer, so you can choose where workspaces and exports are saved.
  • You can decide whether metis should ask about HOC connection types each time.

Faster Starts for Analysis

  • Bootstrap now starts with 500 repeated samples by default, which helps most first runs finish sooner.
  • Bootstrap runs use computer resources more carefully.
  • metis reuses prepared model information where it can, so related analysis steps do less repeated work.
  • Analysis logs now include timing and Bootstrap setting details for easier troubleshooting.

Installation

  • New Windows and macOS installers are available.
  • Bundle builds are checked more carefully to make sure the included R support is ready.
  • Bundle and Lite release settings were updated for a cleaner install experience.
  • The release process was simplified so future builds are easier to maintain.

Everyday Use

  • Model arrows are easier to read, including indicator links, main model paths, and HOC relationships.
  • Dataset loading and app startup are smoother.
  • Some difficult calculation errors now produce clearer messages instead of stopping without enough context.

Reliability

  • More checks now run before a release is published.
  • Windows and macOS builds have safer installer checks for a more dependable install.
