Breaking Changes

None in this release.

New Features

Slope Classification Panel Enhancements

• Added: Slope Report Dialog with three tabs — cumulative frequency chart, tabular summary, and regulatory definitions
• Added: Custom degree ranges editor with editable min/max values and labels, plus one-click reset to defaults
• Added: Geometry validation pipeline for reliable server-side analysis — automatically cleans invalid coordinates, removes duplicate vertices, ensures proper ring closure, and drops invalid polygon parts
• Added: Layer selection support for Map Image Layers with polygon sublayers
• Added: Preset box and circle shapes with interactive transform editing and size limit enforcement
• Added: Contextual tool hints displayed when drawing, selecting, or editing shapes
• Added: Proportional bar chart in results table for visual slope distribution comparison
• Improved: Standardised terminology from "analyze" to "analyse" for consistency

Bug Fixes

Bookmark Restore — Layer Compatibility

When a bookmark is loaded, the map may restore group layers in an optimised format. This previously caused failures across multiple editors because they did not recognise the optimised layer format.

• Fixed: Wildfire Editor now correctly handles both standard and optimised layer formats when selecting features from bookmark-restored layers
• Fixed: Spray Editor and Cart Route Editor now correctly handle optimised layer formats in the same way
• Fixed: All editors (FPP, Plan Burn, Sketch, Cart Route, Wildfire, Spray) now correctly identify features from the specific sublayer, preventing unrelated features from being returned
• Fixed: Layer type handling broadened across editors to support all layer formats encountered during bookmark restore

Panel Toggle Behaviour

• Fixed: Adjusted toggle logic so panels close fully before new panels open, preventing popup display conflicts
• Fixed: Improved popup handling on map clicks to correctly respect whether popups are enabled or disabled

Measure Panel

• Fixed: Area measurement calculation bug that produced incorrect results

Editor Stability

• Fixed: Editors now check whether the panel is still active after completing background operations, preventing actions from executing on a panel that has already been closed
• Fixed: Removed debug logging statements from Sketch Editor and Map Editor

System Improvements

Accessibility

• Added: Screen readers now announce new slope classification results automatically
• Added: Contextual hint messages for active tools (drawing, selecting, editing) across analysis panels

Performance & Stability

• Improved geometry processing with automatic removal of invalid polygon parts
• Stale drawing instance cleanup and timeout management for analysis panels
• Layer selector event listener cleanup on panel close to prevent memory leaks
