 App .NET MAUI Blazor Hybrid per Android, iOS, Mac Catalyst e Windows, pensata per consultare mappe catastali e lavorare sul campo con GPS.
 
+## Versione 0.4.8
+
+- Aggiornamento a .NET 10 e target Android API 36.
+- KML e KMZ generici conservano punti, linee e poligoni; il filtro particelle viene applicato soltanto ai file riconosciuti come catastali.
+- Android propone LME tra le app disponibili per aprire KML, KMZ, GeoJSON, progetti JSON e backup ZIP.
+- I selettori file Android mostrano correttamente progetti condivisi e backup con estensione composta.
+
+## Versione 0.4.7
+
+- La ricerca nel pannello Layer conserva correttamente posizione e selezione del cursore durante il filtraggio; digitando `pio` il testo non viene piu invertito in `oip`.
+- L'elenco revisioni viene aggiornato dopo salvataggi manuali e automatici, rinomina, importazione e selezione del progetto.
+- Il pannello Progetti mostra quante revisioni sono disponibili e spiega quando un progetto appena creato non possiede ancora versioni precedenti.
+
+## Versione 0.4.6
+
+- `Mostra cornice/layer del foglio` carica dal WFS ufficiale AdE il vero confine `CP:CadastralZoning` di ciascun foglio delle particelle.
+- Le particelle appartenenti a fogli diversi producono cornici distinte, senza piu creare un unico rettangolo cumulativo tra aree lontane.
+- Le cornici gia presenti nel progetto o trasferite in un altro gruppo vengono riconosciute e non vengono scaricate o duplicate.
+- Ogni foglio e salvato come oggetto autonomo e puo essere rinominato, bloccato, rimosso o spostato in un altro gruppo dal pannello Layer.
+- I vecchi riquadri cumulativi generati automaticamente vengono rimossi durante il caricamento e sostituiti dai fogli ufficiali.
+
 ## Versione 0.4.5
 
 - Corretto il layout del pannello Layer sui telefoni e sui foldable: checkbox, lucchetto, ordinamento e freccia di espansione non si sovrappongono e restano allineati.
