LegendsViewer-Next v1.3.0 Release Notes

I'm excited to release Version 1.3.0 of LegendsViewer-Next! This release brings major feature additions, including an overhaul of the interactive map, generic filtering across all major world objects, World Records & Hall of Fame, geography & world objects overhaul, backend performance optimizations, parser refinements, and bug fixes.

🌟 Highlights & Major Features

🗺️ Interactive Map & Location System

• Multi-Site Tile Support: Support displaying and selecting multiple sites located on the exact same map tile/coordinates. (THX @tomas-masin)
• Interactive Map Previews for Wars & Battles: Added interactive map previews and direct map focus buttons for Wars and Battles, making it easy to visualize war theatres and battle locations (#22).
• Enhanced Location Markers: Object location markers now feature full-canvas crosshairs, high-contrast target rings, pulse animations, and optimized z-index layering above map graphics (#59, #67).
• Graceful Handling of Unpositioned Objects: Improved handling for entities and world objects without explicit map coordinates (#59).

🔍 Generic Filtering Across All World Objects

• Comprehensive Multi-Criteria Filtering: Added generic filtering drawers and popups for:
  • Entities: Filter by civilization status, active sites, deity worship, entity type, current site count, and war count.
  • Sites: Filter by occupied status, structure presence, site type, structure count, and battle count.
  • World Regions: Filter by biome, alignment/evilness, site presence, force presence, tile size, and site/battle counts.
  • Artifacts: Generic filtering by item type, material, and location/possession status.
  • Wars: Generic filtering by participant entities, start/end dates, and battle count.
  • Structures: Generic filtering by structure type, site location, and relationship lists.
  • Written Content: Generic filtering by form, author, and subject.
  • Battles: Generic filtering by war parent, combatant entities/sides, and casualty counts.
  • Global Event Types: Generic event type filter modal across historical figure and world event timelines (#33).
• Filter UX Guarding: Preserved active dropdown selection states across reactive filter updates.

🏆 World Records & Hall of Fame

• New Records View: Introduced a dedicated World Records page featuring leaderboards across 6 categories (Warfare, Sovereigns, Lore, Intrigue, Longevity, Geography).
• Cached Calculations: Integrated fast backend record calculations with in-memory caching and automatic cache invalidation upon loading new worlds.

⛰️ Geography & World Objects Overhaul (Constructions, Rivers, Mountain Peaks, Regions)

• World Constructions (Roads, Tunnels, Bridges):
  • Overhauled spatial linking: connects start/end sites, master routes, surface/underground regions, crossed rivers, and sub-sections.
  • Smart region resolution based on construction type (Roads link surface regions, Tunnels link underground regions, Bridges inherit master route type).
  • Enhanced Construction.vue layout with direct region/river link cards and length (squareTiles) column in overview tables.
• Rivers:
  • Calculated river length (Length) and bidirectional spatial linking to Regions, Sites, and World Constructions.
  • Enhanced River.vue view and introduced filtering by length, region count, site count, and construction count.
• Mountain Peaks:
  • Added global height ranking (WorldRank) and regional height ranking (RegionalRank) across all peaks in the world and parent regions.
  • Added volcano detection (IsVolcano) and peak height filtering.
  • Enhanced MountainPeak.vue and MountainPeaks.vue with rank badges and elevation metrics.
• Underground & Surface Regions:
  • Integrated spatial cross-linking between surface regions, underground regions, sites, rivers, constructions, and breach events (Breaches).
  • Enhanced detail views (Region.vue, UndergroundRegion.vue) with structured relationship cards and link lists.

📜 Timelines & Detail Pages

• Monarch Line & Position Timelines: Added chronological position timelines and monarch lists for Entities (#20).
• Structure Details Card: Added metadata cards and relationship lists for structure detail pages.

🚀 Backend Performance & Parser Improvements

• Background XML Parsing: Offloaded XML parsing to background Task.Run threads to prevent thread pool starvation during heavy file loading (#34).
• Parser Support:
  • Added support for preservebody circumstance in ArtifactCreated events.
  • Refined vampire filter logic and deity major curse creature type detection (#68).
  • Cleaned up raw HFEXP slayer race tags in HfDied formatting.
  • Fixed structure property merging bug when loading legends_plus files.

🐛 Bug Fixes & Refinements

• Battle Event ID Collision Fix: Resolved synthetic battle event ID allocation colliding with real event IDs when unsupported events are skipped, preventing late battles from linking to unrelated historical events. (THX @Crocatowa, #47)
• Navigation & UI Improvements:
  • Renamed main navigation item from "World" to "Overview".
  • Centered category tabs and persisted active tab state in URL query parameters.
  • Updated documentation and backend run commands in README.md (#50).
