Changelog

0.1.0.4 (Aug. 2, 2026)

Added

• Urban morphology indicators from the Massing Generator: plan area density (lambda_p), open-space and park ratios, direction-dependent gross frontal area density (lambda_f), and building-height mean, standard deviation, minimum, median, 90th percentile, and maximum.
• Optional AnalysisDirection input for directional frontal-area calculations. The vector is normalized in the XY plane and falls back to world X when it is zero or vertical.
• Schema-versioned CaseManifest JSON output containing a deterministic SHA-256 case ID, random seed, installed plugin version, model units, network family and subtype, effective generator inputs, geometry counts, development metrics, and morphology metrics.
• Published JSON Schema for the case manifest at docs/case-manifest.schema.json.
• CITATION.cff metadata for GitHub and Zenodo software citations.
• Dataset-export example in Mycelium-Templates, with morphology metrics and JSON manifest outputs wired to panels for inspection and file streaming.

Changed

• Mycelium Templates now fetches version-matched examples from MyceliumGH-Dev/Mycelium-Templates after the repository transfer.

0.1.0.3 (Aug. 1, 2026)

Added

• Radial–Concentric Grid subtypes in the Massing Generator: full circular Civic Core, straight-sided Polygonal Radial, and a one-sided Fan Plan with a less-permeable rear sector.
• Diagonal Grid subtypes: Single Axis, intersecting Cross Axes, and an Orthogonal Overlay that cuts a wider diagonal boulevard through a regular grid.
• Irregular Grid subtypes: the backwards-compatible Recursive Orthogonal, seeded Deformed Grid, and offset-row Staggered Grid with T-junctions.
• Orthogonal Grid subtypes in the nested right-click menu: Regular Grid, elongated Rectangular Grid, chamfered Cerdà Grid, and Hierarchical Superblock with wider primary streets around 3×3 groups of local blocks.
• Right-click street-network selector on the Massing Generator. The selection is saved with the Grasshopper definition.
• Every published version now gets a git tag and a GitHub Release, cut by CI after Yak accepts the push, with the changelog section as its notes and both .yak distributions attached.
• Re-release guard in the packaging workflow — a publish fails if the version's tag already exists on a different commit.

Changed

• Radial–Concentric Grid now terminates its spokes at a finite central civic block and surrounding ring street, avoiding needle-shaped parcels at the center.
• GitHub Actions pinned to full commit SHAs instead of floating @v4 tags.

Fixed

• Updating Mycelium Templates now clears downloaded template files before synchronizing, so changed .gh/.ghx content is fetched automatically.

0.1.0.2 (Jul. 30, 2026)

Changed

• Redrawn component icon set: all eleven 24×24 PNGs replaced with an isometric set built from a shared engine. File names and ComponentIcons.Get keys are unchanged.
• Plugin logo redrawn from the new assembly mark.

Added

• design/icons/ — the vector source the PNGs come from: per-glyph SVGs, a <symbol> sprite sheet, the myc-vec.js generator, and manifest.csv.
• Mycelium Icon Spec.dc.html — contact sheet for reviewing the set.

0.1.0.1 (Jul. 9, 2026)

Changed

• Yak package name capitalized mycelium → Mycelium.
• Template component now syncs from a branch matching the running assembly version (was hardcoded to main); quick_start.ghx moved out of the plugin into Mycelium-Templates.

Removed

• GitHub Release / Pre-Release workflows. Yak remains the only distribution channel.

0.1.0.0 (Jul. 8, 2026)

First release under the Mycelium name (previously MetaForm). Existing Grasshopper files keep working — all component GUIDs are unchanged.

Added

• Yak packaging and GitHub Actions CI.
• New logo and a complete 24×24 icon set; the Terrain Generator finally has an icon.
• Trees can now actually be generated inside courtyards (the Tree Config GenerateInCourtyards flag was previously parsed but ignored).
• CHANGELOG.md, .editorconfig, and a comprehensive .gitignore.

Changed

• Plugin renamed MetaForm → Mycelium; Grasshopper tab is now Mycelium with panels Massing, Building Types, Vegetation, Site, and Utilities.
• Retargeted from .NET Framework 4.8 / Rhino 7 to .NET 7 / Rhino 8.
• Repository restructured: plugin source under src/Mycelium/.
• Component config wire format now serializes culture-invariantly, fixing broken configs on systems with comma decimal separators.

Fixed

• Assembly info GUID no longer collides with the Massing Generator component GUID.
• Config component base class no longer returns a fresh random ComponentGuid on every call.
• Template component folder labels now use platform path separators (was Windows-only).
