This release adds a shared client runtime and modernises routing, markers, and events. Everything from 1.1 keeps working — the new capabilities sit alongside the existing actions and blocks.

New

• Structured routing output — Map_ShowRoute returns a Route (summary, bounds, waypoints, sections, and turn-by-turn maneuvers with coordinates) ready to bind natively — no more HTML injected into a panel.
• Versatile markers — Map_AddMarker with a custom icon (SVG markup or image URL), optional recenter, and tap-to-open info bubble; plus Map_RemoveMarker and Map_ClearMarkers.
• Info bubble — Map_ShowInfoBubble / Map_HideInfoBubble (a single bubble that repositions, never stacks).
• Map events — center-changed and map-tap (tap returns geo coordinates).
• Map lifecycle actions — get/set center, set zoom, and resize (fixes maps that start in a hidden tab/modal).
• Waypoint labels carried through into the route output (Routing v8 doesn't return them natively).
• Geocoding — forward (GeocodeAddress, address → coordinates) and reverse (ReverseGeocode, coordinates → address) server actions.
• Static map — a HERE map image (Map Image API v3) for a given center, zoom, and size.

Changed

• Routing upgraded to HERE Routing v8 (flexible-polyline, sections & actions).
• SDK loads on demand from HERE's CDN (v3.2) the first time a map is shown, instead of eagerly at module load.
• Markers: AddMarkerToGeolocation superseded by Map_AddMarker.

Fixed / hardened

• Maps in hidden tabs/modals now render at the correct size once shown (ResizeObserver).
• No map/marker leaks when a map is destroyed (explicit teardown).
• Re-routing no longer stacks previous polylines/markers.
• Markers stay reliable after a full clear via the legacy RemoveObjects (the marker layer re-attaches automatically).

Deprecations (still work; use the replacement going forward)

• AddMarkerToGeolocation → Map_AddMarker (custom icon, optional recenter, tap bubble).
• RemoveObjects → Map_ClearMarkers + Map_ClearRoute (granular; RemoveObjects wipes all map objects).
• Previous all-in-one map block → HERE_Map block.
• Previous directions block → HERE_Map + Map_ShowRoute.
• (AddRadiusToGeolocation is not deprecated — no replacement yet.)

Mixing note: RemoveObjects removes objects the new marker/route actions manage. Prefer Map_ClearMarkers / Map_ClearRoute when using the new actions.

Requirements & notes

• Requires a HERE API key (free tier available at platform.here.com). Restrict the in-browser map key by domain; use a separate, unrestricted server-side key for geocoding and the static map (a Trusted-domains-restricted key 401s on server-side REST calls).
• Maps require connectivity — the HERE SDK and map tiles load online.
